The B-52 Band-Pass enclosures combine 18" long-throw subwoofer(s) and a compact 4th order band-pass design which features a sealed top chamber and a tuned port bottom chamber that acoustically eliminates upper frequencies. Acoustic dampening material is also applied to the ported chamber to further eliminate mid/high frequencies. This allows the B-52 band-pass series subwoofers to reproduce undistorted and powerful bass without the use of an electronic crossover.

Each cabinet is constructed of seven layer, 3/4" void-free plywood and finished with impact resistant black carpet. Accessories include: custom handles, metal corners, rubber feet and a terminal plate with (2) 1/4" phone jacks and (1) Neutrik NL 4 Speakon connector. A 3/4" plexi-glass window provides protection from the elements and allows you to see the B-52 subwoofer(s) at work.

Band-pass design has distinct advantages over traditional direct-radiating subwoofers, which includes: easy system connection, higher efficiency (higher SPL) and the ability to produce low frequencies without the use of an electronic crossover. In addition, the sealed top chamber protects the subwoofer(s) from damage associated with demanding low frequency cone excursion. The B-52 subwoofer(s) are fully encased within the cabinet which protects them from physical damage.
