The BF121 is a subwoofer system featuring a single 12″ long-excursion woofer with double-spider suspension and 4″ voice-coil in a bass-reflex configuration. The direct-radiating woofer is mounted in a vented chamber, with large bass reflex port for excellent breathing capacity, increasing overall output while minimizing port-compression. The frequency range is tuned to a -3dB response from 40 Hz to 300 Hz and 33 Hz at -10dB.

The BF121 is driven and controlled by the ALC amplified loudspeaker controller and the integrated factory presets in the drive processor of the ALC offer gain, phase and filtering matching with all Alcons systems, including cardioid projection control presets. The additional front-positioned NL4 connector caters for easy “reverse connection” in cardioid arrays, which can be simulated in ARC, Alcons Ribbon Calculator.

The BF121 is available in road-version and installation version, without handles, wheel dolly board and M20 threaded stand mount flange. It’s finished in Durotect scratch-resistant coating and with Alcons’ Architect Color Option program, the BF121 can be finished in any RAL color.
