SETTING THE 70V TAP
1.		 Using a #2 Phillips head screwdriver remove the two		 screws securing the terminal cover plate.
2. When using speaker wire without conduit, run the		 wire through the hole on the terminal cover plate.
		 Wire needs to be clamped as required by national
		 or local codes. Connect the wires to the terminal		 block being certain to connect the positive wire to		 terminal marked + and the negative wire to the		 terminal marked – .
When using conduit attach the conduit connector to
the terminal cover plate then connect the wires to theterminal block being certain to connect the positive
wire to terminal marked + and the negative wire to theterminal marked – .
3. Using a flat head screwdriver set the transformer
		 tap to the correct tap setting for your installation.
		 We strongly recommend testing the system with		 music to determine the correct output level.
4. Run the speaker wire from the first IS8T speaker in		 the chain to the amplifier terminals. Connect to		 either the right or left channel (+ and -) of the amp.
		 (Sonance DSP 2-750 MKII shown in illustration).
NOTE: Amplifier bridging is NOT supported when in
70V configuration.
WARNING: Do not mount and finish over the speaker
until you have selected the necessary tap setting toachieve the desired volume level. After selecting agiven tap, play the speaker with an actual audio signal
to verify the speaker provides adequate volume. If
necessary, re-select a lower or higher tap setting.

PRODUCT PREPARATION

and in extreme cases, the high frequencies can beattenuated. Amplifier power is also wasted in the wire,
reducing the maximum output level of the system.
Please refer to the chart below when deciding on theappropriate wire gauge for your installation.

Amplifier Selection
Sonance DSP Amplifiers are recommended for use with
the IS8T speaker. When using the IS8T in 70V/100V, we
recommend the Sonance DSP-2-750 MKII. These amps
have preloaded curves to optimize the performance ofInvisible Series speakers and woofers. Preconfigured
curves for various finish types and thicknesses allow for
effortless calibration without the need for additional
measurement equipment. Sonance DSP Amplifiers are
rated down to 4 Ohms and are stable to 2 Ohms. Neverrun more than two Invisible Speakers in parallel on one
amplifier channel.

SPEAKER LOCATION
Invisible Series IS8T speakers have a 170 degree
hemispherical dispersion pattern. This allows for a wide
range of applications and installation locations. It is
recommended that speakers be wall-mounted 7 feet
(2.13 meters) or more above finished floor (AFF) or inceiling to avoid being punctured or damaged. Ensurethat the speaker will not be covered by cabinetry,draperies, art, crown molding or anything that could
cover or puncture the speaker. Face the Wave Flex Drive
Unit away from the ceiling when installing in walls andaway from the walls when installing in ceilings. Ensurethat the back of the speaker has clearance and will not
be adjacent to other building systems such as electrical,
HVAC, pipes, fire sprinklers or others that could violate
local building codes or adversely effect sound quality.

NOTE: Pay attention to Sonance IS speaker rated RMS
power handling. Select an amplifier with max RMS
watts per channel at 4 ohms that closely matches oris less than the IS speaker’s rated power handling (seepage 16). Damage to the speaker or installed finish
may occur if the speaker is overdriven.
Wire Gauge - 70V/100V Systems
The most common wire used on commercial 70
volt systems is 18 gauge, 2 conductor, stranded,and jacketed without a shield. The wire starts at theamplifier location and is paralleled at each speakerlocation.
Wire length using 18 gauge is appropriate up to 700
feet with a 100 watt load. If you double the load (sumof your tap settings), you will reduce the footage byhalf, to 350 feet. Conversely, if you halve the load, you
may double the acceptable wire length, i.e., a 50 wattload is safe over 1400 feet of 18 gauge. Stepping up
to 16 gauge wire extends the allowable run length byapproximately 35%. For example, a 100 watt load cango 700 feet on 18 gauge; the same load may be placedon 1100 feet of 16 gauge.

INSTALLATION ACCESSORIESThe use of space savers and preconstruction zip
rings will assist in better coordination of trades and isrecommended for best results. Space savers are a great
way to reserve the precise dimensions and locationof your Sonance Invisible Series speakers during theconstruction phase and will protect your speaker wirefrom getting lost within the wall or ceiling cavities.
The space saver allows you to delay the installationof the actual invisible speaker to just prior to thefinishing stage. This reduces the risk of damage ortheft of speakers on the job site. If your project calls
for large quantities of invisible speakers, you may use
our preconstruction zip ring brackets as an easy guidefor getting the perfect drywall cutout using a drywall
zip tool. These can be installed in conjunction with thespace savers or on their own and are to be used when
drywall will be laid up directly over speaker locations.
Zip rings are made-to-order, so please contact yourSonance representative for bulk pricing and availability.

4-packFINISH MATERIALS
Prior to speaker installation, verify that the topping
compound and final finish are flexible materials (slowsetting drywall mud/topping compound, wallpaper,
acrylic-based Venetian plaster, thin wood veneer) andwill not exceed 3mm (1/8”).

Wire Gauge - Low Impedance Systems
When using the product in a low impedance system,
the total wire resistance should be less than 10% of the
speaker impedance. The speakers have a nominal 4
Ohm impedance, so your total wire resistance should
be no more than 0.4 Ohms. Simply, the extra resistancefrom the wire will have a very negative affect on thesound quality of the speaker. The sound can be lessdynamic, definition of bass frequencies can be reduced,
5

NOTE: Our recommended target for optimal
performance is between 1.0 and 1.5mm (about 1/16”)of topping compound. Sound quality and installation
durability will be adversely effected if too muchtopping compound is applied. For wood veneer
finishes, use only 20mil (0.5mm) veneer with paper
backing.

up being our recommended target of 1.0-1.5mm (orabout 1/16”). Also emphasize the maximum of 3mm(or 1/8”) finish thickness. Review our guidelines forrecommended materials on page 5 and 14 with thefinish manager.

NOTE: Do not use hard-setting or stiff materials overthe surface of invisible speakers, such as fast-setting
drywall mud (“hot mud”), genuine Venetian plaster,stucco, metal panels, tile, etc.

• Use the Sonance DISC system and DG-1 depth
gauge (SKU 93491) to validate the finish thickness.
It is helpful to lend the gauge to the finish manager
so that it can be used during the actual process.

PRODUCT MANAGEMENT• Once the finish material has completely dried,
perform another room-by-room listening check ofeach speaker. If the speakers do not sound similar
to the performance you heard prior to finishing, it islikely that the finish thickness exceeds the maximumof 3mm (1/8”). Now is the time to correct this byremoving material.

Follow the installation instructions in this manual
precisely to ensure outstanding speaker performanceand true invisibility. To accomplish this flawlessly
every time requires project management and close
coordination with the drywall and finish trades alongwith the General Contractor and sometimes even theclient. Here are some best practices that will prevent
unmet expectations and expensive rework:• Remember: once the flooring is installed and thefurniture is in place, it is too late to remove excess
finish material from the Sonance IS speakers
without significant cost, cleanup, and/or complexity.

• After IS speakers are connected and screwed in but
before any drywall mudding, taping, or finishinghas started, schedule a walk-through with the client(or client’s representative), the General Contractor,
and the finish manager. Listen to every speaker
for a couple minutes. This is the best opportunity
to discover any anomalies or issues with invisible
speaker performance.

Effective project management, sign-offs, and proactive
communication with the trades will prevent unexpected
results and provide consistent, beautiful installs that
wow the client and end-users.

ADDITIONAL INFORMATION• All in attendance should sign off on audio
performance, speaker-by-speaker and room-byroom. Prepare a checklist like the example below
and ask all parties to sign and date, acknowledging
that the Sonance IS speakers perform to everyone’s
expectations.
• Review all installation steps and processes with thefinish manager, emphasizing to cover the speakers
with only enough flexible material to make thespeakers disappear and no more. This typically ends

RETROFIT INSTALLATION
1.

6.

Remove the included cutout template that is taped
to the front of each speaker.

Remove drywall from opening. This should expose
only 3/4” (19mm) of each stud/joist or half of thestud/joist surface. Remove any exposed drywall
nails or screws.

Half (3/4” or 19mm)
of each stud/joist
should be exposed.

2.

Locate the studs in your install location and markthe centers of the studs/joists. Position and affix thetemplate so that it is perfectly centered on both left
and right studs.

7.

Test-fit the speaker into the opening, verifying thatthe center diaphragm area is even with the drywall
edges. If necessary, trim the edges of the drywall toproperly accommodate the speaker.

3.

Mark around the template and remove.
NOTE: We highly recommend you keep the
cutout template. It is an important tool that will
help identify the measurement locations for the
Sonance DISC system during the finish validation
phase.

8.

Run speaker wire from the amplifier and audio
component location to the cut out holes for yourspeakers. See wiring chart on page 5.

9.

We recommend that you reinforce the top andbottom joint locations with a face-block-oriented
2x4 or 3/4” (19mm) plywood. See the construction
diagrams on page 7 and STEP 2 on page 9.
Ensure there is a flush, level surface around thefull perimeter of the speaker location before
proceeding.

4.

Before proceeding, perform an obstruction survey
to be certain that there are no studs, conduit, pipes,
HVAC ducts, pocket doors, etc. in the wall cavity
that will interfere with the speaker.

5.

Cut the drywall using a drywall saw along the
top and bottom and a utility knife along thestud centerlines. An oscillating power saw isrecommended for faster, cleaner results.

10. Proceed to STEP 9 on page 10.

Use utility knife
to cut along studcenterlines.
Use drywall saw to
cut along top andbottom lines up
to inside edges ofstuds.

Use utility knife tocomplete horizontal
cuts.

NEW CONSTRUCTION INSTALLATION
1.

Run speaker wire from the amplifier and audio
component location to desired speaker locations.
See page 5 for wire gauge chart.

2.

We recommend that you reinforce the top andbottom joint locations with a face-block-oriented
2x4 or 3/4” (19mm) plywood. See the construction
diagram on page 7 and the chart below for opening
height dimensions. Product dimensional drawings
are available on www.sonance.com. Ensure there isa flush, level surface around the full perimeter of the
speaker location before proceeding.

4.

Use the wire management built into the spacesaver/zip ring to keep your cables in place. With theaid of a level, screw the space saver/zip ring to thestuds, making sure it’s centered horizontally.

5.

Complete drywall installation to the rest of the room
including the surface around the speakers.
NOTE: Sonance recommends using the included
stainless steel screws around the speaker locations.
This is to avoid interfering with the Sonance
DISC system depth gauge operation after install.
Though this is not required, it will improve theaccuracy of finish thickness measurements later on.

7.

8.

Remove the space saver, if applicable. Hold onto
the speaker wire attached to the back and pull it
through the opening, being careful not to damage
the surrounding drywall. The space saver can be
kept for future installations or recycled.

9.

Connect the speaker wire from your wall or ceilingto the terminals on the speaker.

10. Place the speaker into the opening. In a ceilinginstallation, do not hold the speaker in the center ofthe diaphragm. Hold at the edge of the frame andget assistance from a helper. Secure the speakerusing one of the included stainless steel screws
in each corner (use at least 4 screws total for thisstep).

OPTIONAL: If the zip ring was also used, cut the
drywall at the speaker location using a zip tool andthe zip ring as a guide. Be sure to cut along theoutside edge of the zip ring. It will stay in placepermanently.

NOTE: The best practice is to use stainless screws
to secure the drywall surrounding the speaker aswell. Unlike standard drywall screws, these are
non-magnetic which will improve the accuracy of
the Sonance DISC system later on in the finishingstage.

Install shims to your framing as needed. Half inch
(12.5mm) drywall does not require shims in mostcases. If you are using a thicker substrate such as
5/8” (15mm) drywall, we include a thick 1/8” (3mm)shim to bring the speaker flush to the installation
surface. We also include a full set of thin 1/16”(1.6mm) shims to make installation in a variety of
substrates easier.
NOTE: When using shims, make sure all 4 speakeredges (top, bottom, and sides) are supported for aflush install surface around the entire perimeter ofthe speaker.

10

11.

Ensure the center of the speaker diaphragm (notthe recessed edges) is flush with the surrounding
drywall. Adjust shims if necessary.

PRE-FINISHING TESTINGGUIDELINES
Once a finish is applied to an invisible speaker, it will
be too late to go back and fix any audio connection
or installation problems.
Installation Fit Test
Lightly place a straight edge across the face of the
speaker to verify that the diaphragm of the speakeris co-planar with the surrounding drywall and has
been installed correctly. Adjust shims if necessary. It
is normal for the beveled edge of the speaker to berecessed from adjacent drywall.
Audio Test
Connect a high-quality audio source and Sonanceamplifier to the installed invisible speaker for best
results. Adjust the output for a moderate volumelevel consistent with how the speakers will be
used in the space. Play music to check for overall
fidelity and listen for any buzzes or rattles. We
also recommend a slow tone sweep from 20Hz to
5kHz to help pinpoint any buzzing that could becaused from loose studs/screws/drywall, cablevibration, or rattling of outlets, lighting components,
construction fixtures, etc.

12. IMPORTANT: Test the speaker with an audio source
at moderate listening levels to ensure it functions
properly before completing the installation. Follow
the guidelines on this page carefully.

Fix any installation or audio issues before moving
on to the next steps.

13. Secure the speaker to the surface with theremaining stainless steel screws along all four sides.
Do not over-tighten.

We highly recommend active project management
practices as described on page 6. Only after
passing these testing guidelines should you
proceed to the finishing stage.

FINISHING INSTRUCTIONS

3.

Allow hot mud to set slightly before applying mesh
tape.

4.

Place mesh tape over the drywall seams. Overlap
tape slightly.

5.

Do not tape over the raised portion of the speaker.

NOTE: Drywall finishes can range in various levels ofsmoothness. For invisible speaker installations, werecommend at least a level four finish where drywall
seams are all feathered out and sanded. For best
results, we recommend a level five finish where
the entire wall plane is skim-coated and sanded forsmooth consistency.
1.

2.

Fill the gap between speaker and drywall with 20
minute fast-setting joint compound (“hot mud”).

Feather all edges.

12

6.

Allow hot mud to fully cure and harden.

8.

Feather all surfaces around the joints and up to theraised portion of the speaker diaphragm.

7.

Once hot mud has fully cured, cover joints withslow-setting compound.

9.

Allow first coat to fully cure. This can take 12–24
hours.

NOTE: DO NOT use fast-setting drywall compound(“hot mud”) to cover the speaker; it is not flexible
enough to provide a durable finish for invisible
speakers. Instead we recommend a lightweight allpurpose joint compound to cover joints and feather up
to the surface of the speaker. Lightweight, easy-sandtopping compound should be used for covering the
speaker.

IMPORTANT: If a perfectly flat finish is achieved at
this point, you may opt to proceed to the priming andpainting phase. This is what we refer to as a “Finish Up
To” installation. In this case, we recommend multiple
layers of paint to achieve a shadow-less, even blendingof color.
We highly recommend a “Finish Over” process wherean additional skim coat is applied over the entire
speaker and blended into the surrounding wall plane.
A Finish Over process typically takes less time tocomplete versus Finish Up To because fewer layersof paint are needed. And with the skim coat over theentire surface of the speaker and wall, it’s much easierto achieve perfect invisibility.

FINISH THICKNESS GUIDELINES

Compound buildup on the active surface of the
speaker should not exceed 3mm (1/8”).

Sound quality and installation durability will be
adversely effected if finish materials are applied too
thick.
TOTAL FINISH THICKNESS FOR OPTIMALPERFORMANCE: 1.0mm to 1.5mm (3/64” to 1/16”)
MAXIMUM TOTAL FINISH THICKNESS: 3mm (1/8”)
Validate finish thickness using the Sonance DG-1
depth gauge (SKU 93491).
Do not use hard-setting or stiff materials over thesurface of invisible speakers, such as fast-setting
drywall mud (“hot mud”), genuine Venetian plaster,stucco, metal panels, tile, etc. Use only flexible
materials to finish invisible speakers.

12. Detail the compound to minimize tool marks.

When using flexible sheet materials such as
wallpaper or veneer, ensure that the total thicknessof any drywall compound, adhesives, and thefinishing substrate itself does not exceed 3mm(1/8”). For wood veneer finishes, use only 20mil(0.5mm) veneer with paper backing.
10. Apply a second coat of topping compound covering
the entire surface of the speaker and all adjoining
surfaces.

13. Allow each layer to fully cure. This can take 12–24
hours.
14. Build more coats as necessary to achieve desired
finish. Each successive coat should be thinner thanthe last. The final coat should be a very light skimcoat application.

1415. After final coat is applied and has dried, use amanual pole sander or block sander on entire wall
(do not use a power sander as this could damage
the surface of the speaker). Be careful not to sanddown into the surface of the speaker. This could
damage the paper which makes perfect blending
very difficult to achieve. Wall surface should show
no signs of a speaker.

16. Validate the finish thickness using the Sonance DISC
system and DG-1 depth gauge (SKU 93491).

17. The final step is to once again perform an audio
test. Listen to each speaker and verify that audio
quality and performance have not significantly
changed since your initial listening test just prior to
the finishing stage. Now is the best time to fix any
audible anomalies or surface imperfections.
After listening validation, your Sonance Invisible
speaker installation is now complete. From thispoint, follow your normal method for final finishingwith flexible materials such as paint, wallpaper,
veneer, and so on.

FREQUENTLY ASKED QUESTIONS

How can I tell how much finish material is covering the
speaker?
Use the Sonance DG-1 depth gauge (SKU 93491) tomeasure actual finish thickness covering Sonanceinvisible speakers.

Can Invisible Series speakers be installed in the ceilingor just in walls?
Sonance IS speakers can be installed in both walls andceilings.

What is the DISC system?
The Sonance DISC System provides a highly accurate
method for non-destructively quantifying the thicknessof a finish applied on top of a Sonance invisible speaker
diaphragm. The Sonance DG-1 handheld depth gaugeuses a magnetic sensor to measure the distance
between the top of the finished speaker and steel
discs embedded in all four corners behind the speaker
diaphragm of Sonance Motion Flex Invisible Speakers.

Where is the best place to locate the speakers?
If installing into walls, make sure they are at least 7’(2.13m) from the floor. In ceilings, evenly space thespeakers for optimal coverage, and avoid corners if
possible. Contact Sonance Tech Support / Design
Services for help with speaker layout planning.
What is the minimum depth requirement?
Minimum depth without enclosure = ~2.75” (70mm)
Minimum depth with enclosure = ~3.5” (90mm)

What if I add too much finish material?
Prior to the final finishing stage (such as painting),sand down the wall or ceiling surface and measure thefinish thickness using the DG-1 depth gauge. Repeat
as necessary until you measure 3mm or less. We
recommend 1.0mm and 1.5mm for optimal performance.

Can IS speakers be used in a plenum space?
Only models with a “T” suffix such as the IS8T are rated
for plenum use (UL2043). The standard models (IS6/
IS8/IS10/IS10W) are not plenum rated.

Is there a benefit to “Finish Up To” rather than “Finish
Over”?
There is no practical benefit to a Finish Up To stylefinish. In fact, we recommend Finish Over because it
typically takes less installation time and results in amore seamless, shadowless final finish. Furthermore, IS
speakers are optimized for about 1.0mm to 1.5mm offinish material for best performance.

Can these speakers be installed in a T-Bar ceiling?
Theoretically yes. Consult with the manufacturer of the
T-Bar ceiling in question to ensure the max load is withinsafe limits for the aggregate weight of the IS speakers
you wish to install.
Can these be used outside?
Sonance invisible speakers are not outdoor rated andshould not be used outside.

What happens if the mud or finish cracks?
Mud/finish cracks are indicative of either an improperly
applied finish or invisible speakers that have been
regularly overdriven. Though the integrated poly fuses
mitigate against damage, they cannot protect against
every type of abuse. Remember, just like traditional
speakers, invisible speakers have their limit. However,the difference is when a traditional speaker fails due toover-exertion, only the speaker is damaged; whereas
with invisibles, the finish can sometimes be damaged aswell.

Can these be used in high heat or high humidity
applications?
Invisible speakers should not be directly exposed
to high heat or humidity. However you may use
finishing materials that are rated for high heat andhumidity exposure, provided that they form a barrierthat prevents exposure to the speakers. We highly
recommend you perform a mock-up trial of the finish
materials, speaker, and environment to validate theperformance long-term.

Though it is rare, if a crack occurs, Sonance will help
troubleshoot the issue on a case-by-case basis. We
typically start by inspecting the finish process. In mostcases, the finish was applied too thick (outside of our
specifications). With our new DISC system, we havethe ability to prevent these types of failures before
they even happen by identifying and correcting at the
installation phase. This is why we highly recommend
taking advantage of the DISC system during installation
to prevent problems down the road.

What finish materials can I use with invisible speakers?
Can these be covered with wallpaper or wood veneer?
Use flexible materials such as: slow-setting, lightweight
drywall compounds, wallpaper, wood veneer, vinyl
veneer, acrylic-based venetian plaster. See page 14 formore details.
Are there materials that should not be used to cover
the speakers?
Any material that is stiff, inflexible, or exceeds 3mm(1/8”) in total thickness over the speaker diaphragmsuch as tile, metal sheet, stone veneer, true Venetianplaster, stucco, etc. These are not compatible withinvisible speakers. The stiffness of materials like theserestrict movement and result in lack of bass and muffledsound.

Can I use other than Sonance DSP amplifiers?
Yes, but we highly recommend Sonance DSP amps dueto the built-in DSP preset curves. Pay close attention
to Sonance IS speaker rated RMS power handlingand select an amplifier whose maximum RMS watts
per channel closely matches or is less than the IS
speaker’s rated power handling. If the amplifier’s power
capabilities exceed those of the speakers, damage tothe speaker or installed finish may occur if the speakeris overdriven. For Sonance IS woofers and subwoofers,
always use a Sonance DSP amplifier to drive them.

How much finish material can go over the speaker?
We recommend 1.0mm to 1.5mm for optimal
performance. The maximum limit is 3mm (1/8”).

I lost the screws. What is the spec or do I have to buy
them from Sonance?
Use stainless steel #6 drywall screws in the appropriate
length depending upon drywall/installation substratepanel thickness and local codes.
I lost the shims. How can I get more? Do I have to buy
them from Sonance?
Use standard drywall shims available from your local
hardware store.
Is there a protection circuit built into the speaker ordo they need to be added?
Every full-range speaker in the lineup (IS6T/IS8T) has
dual, self-resetting poly fuses: one dedicated to eachtransducer. The woofers have a single poly fuse. If a
speaker is overdriven, one or both of the poly fuses
will trip, and the transducers will cease to make soundwhich protects both the driver and the installation
surface from damage in overdrive conditions. After a
few minutes, the fuses will reset, and the speakers will
perform as normal. If the poly fuses are tripping, that’s
a sign that the speakers are being overdriven, and you
should decrease the volume. If you want more volume,
add additional invisible speakers to your space.
What is the warranty on IS invisible speakers, andwhat does the warranty cover?
The 15 Year limited warranty covers the cost to replace
the speaker(s) and refinishing up to level 5 drywall
finish.
