The BF302 is a front-loaded subwoofer system, for both permanent and portable applications.Featuring double 15” long-excursion high-power woofers (with vented double-spider frame), the BF302 delivers high quality, tight and accurate bass response. The SIS pre-wiring ensures complete cable/connector compensation between the BF302 and ALC. Typical applications for the BF302 include bass extension of main sound systems, used in multiples depending on the application and low frequency requirements. The higher tuning makes the BF302 an ideal high-power punch-bass system for live- or club sound, in combination with an Alcons top cabinet / array.For full system performance, we recommend using the BF302 in combination with an ALC4 (or ALC6) amplified loudspeaker controller. Driven by the ALC, the BF302 delivers maximum sound quality and output power with dedicated and inaudible (power and excursion) protection (SDP circuit).
