Product description

The BF302 is a high-performance subwoofer system, delivering tight and accurate bass response with very low distortion. It features double 15” long-excursion woofers, with vented double-spider frame and 4” voice-coil for a stable and prolonged high output.

Each direct-radiating woofer is mounted in its own individually-vented chamber with large bass reflex ports 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. It is finished in Durotect™ scratch-resistant coating and is fitted with 8 handles for easy logistics (road-version).

For full system performance, the BF302 is driven and controlled by the ALC amplified loudspeaker controller; Driven by the ALC, the BF302 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 BF302 is SIS™ pre-wired: Through the Signal Integrity Sensing circuit of the ALC, the cable-length and connector resistance between the BF302 and ALC is dynamically compensated (system damping factor 10.000), further reducing distortion, while increasing response accuracy.

The BF302 is available in road-version and installation (“i”) version, without handles and wheel dolly board. Through the Architect Color Option™ program, the BF302 can be finished in any RAL™ color.
