An aluminum front panel heat sink dissipates heat in the subwoofer
compression chamber. This provides greater power handling, more overall output
and cooler long-term operation. The LX-18 is finished in a rugged, impact-resistant
black carpet. Void-free, 7-layer, 3/4” plywood construction for maximum
durability and minimum weight. Input connections: (2) 1/4” metal phone
jacks; (1) Neutrik NL 4 Speakon Connector. Reinforced internal bracings are
used to fortify the LX-18E.
ALUMINUM HEAT SINK

CABINET CONSTRUCTION. The LX-1818A cabinet is built for the abuse of the road. Each enclosure is constructed with 3/4” plywood and includes metal carrying handles, protective metal corners and 4” casters. A lifetime cabinet construction warranty is provided.
INTERNAL COMPRESSION CHAMBER
The B-52 18” subwoofer’s acoustic load is controlled by a specially designed horn and compression chamber that minimizes the excursion of the driver while maximizing the system's output. The optimally-sized acoustic aperture of the compression chamber forms the throat of the horn and helps to force air through the horn at an increased velocity and pressure. The compression chamber optimizes the horn's output and the acoustic impedance seen by the B-52 18-200L transducer. It is this acoustic impedance transforming “phase-plug” design that enables the LX-Series subwoofers to achieve amazing and unprecedented output levels.
18" SUBWOOFER INSIDE THE COMPRESSION CHAMBER
The B-52 18-200L 18” subwoofer
features a cast-aluminum frame, 200 oz vented magnet structure, bumped back-plate for greater excursion and 4” dual-layered tempered aluminum voice coil former. The voice coil is wound with four layers of 26-gauge copper wire, optimally sized for this motor. A rock-solid tilt-back metal bar handle for increased mobility. LX-Series subwoofers include 4” heavy-duty casters, providing ease of mobility and increased cabinet longevity.
