The LF3 pro is a high performance single 18-inch horn loaded subwoofer that incorporates the advantages of the very successful LF1+ subwoofer into an extremely compact subwoofer. A derivative of the LF1, the LF3 pro design utilizes unique Sub-horn cabinet construction. This design behaves like a horn over much of its range, but without the time delay and weight problems usually associated with conventional designs. Vented-box advantages take over for the lowest octave and assist in producing exceptionally high levels of clean, punchy bass from a modest-sized box.
A specialized B&C 18-inch 1300W woofer is loaded to ensure chest-kicking low frequency, extremely long-term power handling and reliability in all applications. The reverse woofer orientation has been used to optimize the rear chamber volume and decrease the horn flare rate for extended low-end performance. When used with the MH3pro, MH7pro,XLA1,XLA3 or Elite full-range speaker systems, the LF3 pro provides high-output sound reinforcement for clubs, large halls, or outdoor events in a compact package which can be moved easily by a one-person crew.
The LF3 pro rectangular cabinet can be easily ground stack in multiples to increased low frequency directivity and level. When two speaker systems are placed as opposites side by side, the woofer cones mutually couple, causing the two systems to act as one system with twice the effective cone area at very low frequencies, giving an additional 3dB increase in maximum acoustic.
