Product description
The BF121 is a high-performance subwoofer system, delivering tight and accurate bass response with very low distortion. It features 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 minimising port-compression.
The double baffle board and the combination of complex internal panel lay-out with extensive bracing brings a rigid structure with a high enclosure stiffness from a relatively low-weight package.
For full system performance, the BF121 is driven and controlled by the ALC amplified loudspeaker controller; Driven by the ALC, the BF121 delivers maximum sound quality and output power with long-term operation reliability. The integrated factory presets in the drive processor of the ALC offer gain, phase and filtering matching with all Alcons top systems, including cardioid projection control presets. The additional front-positioned NL4 connector caters for easy “reverse connection” in cardioid arrays.
The 4 ohms system impedance, makes for a very efficient amplifier loading; Thus enabling maximum output from a single, very compact configuration.
The BF121 is SIS™ pre-wired: Through the Signal Integrity Sensing circuit of the ALC, the cable-length and connector resistance between the BF121 and ALC is dynamically compensated (system damping factor 10.000), further reducing distortion, while increasing response accuracy.
The BF121 is available in road-version and installation (“i”) version, without handles, wheel dolly board and M20 threaded stand mount flange. It is finished in Durotect™ scratch-resistant coating; Through the Architect Color Option™ program, the BF121 can be finished in any RAL™ color.
The BF121 packs the same punch and accuracy as its bigger brothers BF151 and BF181 compact subwoofers, and is a perfect companion for the VR5 monitor as super-compact PA system.
