The BF121 subwoofer system is available in road and installation (i) versions

Alcons Audio has developed its smallest subwoofer system to date for delivering accurate bass response with low distortion. The BF121 incorporates a single 12-inch long-excursion woofer with a double-spider suspension and a 4-inch voice coil in a bass-reflex configuration.

The direct-radiating woofer is mounted in a vented chamber, with a large bass-reflex port designed for increasing overall output while minimising port compression. Operating within a frequency range of 40–300Hz (–3dB response), the BF121 is powered and controlled by the ALC amplified loudspeaker controller. Integrated factory presets provide gain, phase and filtering matching with all Alcons systems, including cardioid projection control presets. 

The additional front-positioned NL4 connector caters for a reverse connection in cardioid arrays, which can be simulated in the Alcons Ribbon Calculator. The BF121 is pre-wired with Signal Integrity Sensing ALC circuitry, while the cable length and connector resistance between the BF121 and ALC is dynamically compensated to reportedly reduce distortion, yet increase response accuracy.

Like the 15-inch BF151 and 18-inch BF181, the BF121 features a 4Ω system impedance, enabling maximum output from a single transducer configuration. The BF121 is available in road and installation (i) versions, without handles, wheel dolly board and M20 threaded stand mount flange. Finished in Durotect scratch-resistant coating, the BF121 can be manufactured in any RAL colour from the Architect Colour Option programme.
