The LF7 pro is a high performance dual 18 inch twin horn subwoofer that incorporates the advantages of the very successful LF1 woofer into a compact yet powerful subwoofer that delivers twice the volume.
A derivative of the LF1, the LF7 pro design utilizes the unique double Sub-horn cabinet construction with two Italian woofers to ensure chest-kicking low frequency, extremely long term power handling and reliability in all applications. 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.
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 MH& pro mid-high speaker, the LF7 pro provides high output sound reinforcement for clubs, large halls, or outdoor events in a compact package which can be moved easily by a two-person crew. Although the LF7 pro was designed for use with the MH7 pro systems, it may be used to add to the bass performance Lloyd Lee Co. EDGE-X and ENCORE speaker systems also.
The LF7 pro rectangular cabinet can be easily ground stack in multiples for increased low frequency directivity and level. When two speaker systems are placed 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 output.
