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 to upper-/under-balcony, up to "stealth-mounted" system in stair risers or walls.
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 horizontally controlled dispersion and 800W peak power handling, the SR9 system features 120 horizontal coverage with a super fast transient response for unsurpassed intelligibility and a "digitally" dynamic response.
The narrow 15 vertical coverage offers maximum "gain-before-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 low-frequency response.
The extreme low height and shallow depth, combined with the specially recessed connector plate make the SR9 fit inconspicuously in virtually any (show deck) space; It can be placed on stage or mounted under balcony with minimal sightline obstruction.
For full system performance, the SR9 shall be used in combination with an ALC controller-amplifier, offering a number of "system-synergy" advantages:
- The passive system includes dedicated cross-over filtering, but system equalizing is done remotely (electronically) in the ALC, fully utilizing the individual speaker components' output capacity. This results in increased headroom SPL above 800Hz. of 6dB.
