Important Safety Instructions
This symbol warns the user of dangerous voltage levels
localized within the enclosure.

This symbol advises the user to read all accompanying
literature for safe operation of the unit.
∆ Read, retain, and follow all instructions. Heed all warnings.
∆ WARNING: To prevent damage, fire or shock hazard, do not
expose this unit to rain or moisture.
∆ This product should be located away from heat sources such asradiators, heat registers, or other products that produce heat.
∆ This product should only be used with a cart or stand that isrecommended by the manufacturer.

S W R ® Wo r k i n g P r o ™

Congratulations on your decision to make a WorkingPro™
bass speaker enclosure part of your bass amplification
system. Since 1984, we here at SWR® have been putting
everything we know about bass into the SWR® product line.
We’ve earned a reputation for designing and manufacturing
gear that has changed the way bassists hear themselves.
That’s why you’ll find our bass amps, cabinets, and combos
on stages and in recording studios around the world—andwhy you’ll hear SWR® on countless recordings, spanning all
genres of music.

Inside this owner’s manual you’ll find specifications,features, and usage suggestions for every WorkingPro™
bass speaker enclosure we make. New SWR® user andseasoned user alike will benefit from reading through thisbrief but informative manual.
Thank you for choosing SWR®.
Sincerely,
SWR

Connections and Operation
INPUT PANEL
Tweeter Attenuator Control {A}This level control adjusts the loudness of the tweeter(high–frequencies). A normal setting for this control isstraight up (twelve o’clock). Turn the dial fully counterclockwise to remove the tweeter from the circuit. Turn thedial clockwise to increase the high frequency content. NOTE:
Any amplifier clipping (distortion) that occurs will always beaccentuated by the tweeter. Turn down the master volume
on your amplifier to reduce the clipping. See Troubleshooting
below if clipping persists.
An internal (passive) crossover divides the signal, sending
frequencies above 5kHz to the tweeter and those below
5kHz to the drivers.

IMPORTANT INFORMATION• ONLY connect one amplifier to your bass speakerenclosure(s). Two amplifiers WILL NOT work and may
damage your equipment.
• DO NOT connect speakers with a total impedance load
below the minimum rating of your amplifier to prevent
damage to your equipment. See Impedance Guidelines.
•ONLY connect speakers with a total power handling
capacity that is above the power output rating of youramplifier to prevent damage to your equipment.
• ALWAYS switch your system power OFF before
connecting or disconnecting speakers.
• ONLY use unshielded speaker cable of 18 gauge or
heavier (such as 16 or 14 gauge) for speakerconnections. Shielded instrument cable WILL NOT workand may damage your equipment.
• SWR® RECOMMENDS removing the casters from theWorkingPro™ 4X10T during performance so the cabinet
contacts the floor, extending your bass response.

Input and Output Jacks {B & C}
WorkingPro™ Series speaker enclosures feature both
1/4" {B} and Speakon® {C} input/output jacks to provide
flexibility in making your speaker connections. Use theSpeakon® jacks whenever possible to take advantage of theirsuperior power transfer efficiency and locking connectors.
All four jacks are full range and wired in parallel.
Multiple Speaker Enclosures {D}You can connect multiple WorkingPro™ speaker enclosuresto your amplifier within limits (see Impedance Guidelines
below). Connect the first speaker to your amplifier as usual,then connect the second speaker to an OUTPUT jack on thefirst speaker, and so on.

IMPEDANCE GUIDELINES
Use the impedance ratings on your amplifier and speakers todetermine if a par ticular combination of speakers isappropriate for your amplifier. NOTE: All SWR® bass speakerenclosures (and most others) are wired in parallel(NOT series), therefore, these Impedance Guidelines apply
only to parallel speaker connections. The Illustration belowshows the total impedance loads of various combinations ofspeakers connected in parallel.

✧ s w r s o u n d . c o m✧Bass Speaker Enclosures
Generally, you will want toconnect your amplifier tospeakers with a total impedanceload equal to the minimum
impedance rating of youramplifier. Operating below theminimum impedance rating caneasily overheat the amplifier andcause damage. Operating above
the minimum impedance rating
will reduce the amplifier’smaximum power output.
Noticethatdifferent
combinations of speakers canequal the same total impedanceload. If their impedances are thesame, each speaker will receive equal power from youramplifier. However, if their impedances are not the same,
speakers with the lowest impedances will receive the mostpower. For example, if 4Ω, 8Ω and 16Ω speakers areconnected, the 4Ω speaker will receive most of the power
and the 16Ω speaker will receive almost none of the power.
Take this into consideration when calculating power handling
capacities and when positioning your bass speakerenclosures.

CLEANING AND MAINTENANCE
A soft, dry cloth can be used to remove smudges orfingerprints from the speaker grill. A stiff brush can be used
to keep the carpeting clean. Should the carpet acquire anodor (from smokey clubs, etc.) a common carpet cleaner canbe used according to the product directions.
Cabinet Vibration
Periodically check for and tighten loose screws to prevent
any rattles or air leaks. There are screws on the baffle andinput panel as well as the steel grill. Do not over-tighten thesteel grill screws which may compress the rubber standoffs
and cause interference between the grill and the speaker(s).

TROUBLESHOOTING
I hear unwanted distortion... First identify the source:
Temporarily replace each cable, then the amplifier in turnwith a tested substitute. Turn off the tweeter to isolate thewoofer. If you hear no improvement at any point, contact anauthorized SWR/FMIC service center.
Multiple speaker enclosures have a hollow, thin sound...
Test for reversed wiring: Pull thespeaker cable plug from the amplifier.
+–
Each woofer should move out9V(towards the grill) when a 9 volt
battery is applied as shown. If not,temporarily replace each cable in turn with a tested
substitute. If you see no improvement at any point, contact
an authorized SWR/FMIC service center.
