As “signature” of all Alcons designs, the SR9 combines remarkable clarity and intelligibility with high SPL. Loaded with the RBN401 pro-ribbon driver, with its patented wide, horizontally controlled dispersion, the system features 120° dispersion with a 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.

The low height and shallow depth, combined with the specially recessed connector plate make the SR9 fit inconspicuously in virtually any space.

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

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

For full system performance, the SR9 shall be used in 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 and excursion) protection (SDP circuit).
