intelligibility and SPL output
Very low profile enclosure for minimal sightline

Durotect™ scratch-resistant coating

As “signature” of all Alcons designs, the SR9
combines remarkable clarity and intelligibility withhigh SPL. Loaded with the RBN401 pro-ribbon
driver, with its patented wide, horizontally controlled
dispersion, the system features 120° dispersion witha super fast transient response for unsurpassed
intelligibility and a “digitally” dynamic response.
The narrow vertical coverage offers maximum “gainbefore-feedback” directly above (on stage) or under(orchestra pit) the speaker. The double 5” woofers
are non-vented, for a smooth low-end roll-off; This
sealed box tuning enables easily adjustable lowfrequency response.

description

The low height and shallow depth, combined withthe specially r���������������������������������
ecessed connector plate make theSR9 fit inconspicuously in virtually any space.

The SR9 is a passive 2-way ultra-compact
loudspeaker, specifically designed for applications
where ultimate fidelity response needs to be
projected with wide horizontal and precise vertical
coverage.
Typical (short to medium throw) applications for
the SR9 range from low-profile stage-lip/front-fill

The system includes dedicated filtering, but system
equalizing is done remotely (electronically) fullyutilizing the individual speaker components’ outputcapacity. This results in increased headroom SPL
above 800Hz. of 10dB.

(on-stage or in show deck) to upper-/underbalcony up to “stealth-mounted” system in stair������risers or walls.

The SignalIntegritySensing™ pre-wiring ensures��������
complete cable/connector compensation between
the SR9 and ALC.

Due to Alcons Audio continuous R&D, all specifications are subject to change without prior notice.

For full system performance, the SR9 shall be usedin combination with an ALC amplifier/controller.
Driven by the ALC, the SR9 delivers maximum
sound quality with increased headroom, under
dedicated equalisation and inaudible (power andexcursion) protection (SDP circuit).
