Lowell's DX104 backbox for 4-inch speakers is acoustically engineered for professional sound installations where the highest quality sound reproduction and fidelity must be attained. It is an acoustically treated large volume design allowing a 4-inch loudspeaker to operate at optimum loading level and to achieve improved low frequency response with rich, full bass. Backbox Model DX104 is 10"Dia. x 6.75"D with an additional 3/8"D formed flange for attaching screw mount grille Model WB-4 (order separately). The DX104 is fabricated of welded 22 gauge steel and undercoated to eliminate acoustic and metallic resonance. Additionally, it is lined with 1.5" thick batted lining with a density rating of 1.5 pounds to neutralize undesirable resonance in the high frequency range. For conduit access, the backbox is furnished with four combination 1/2 - 3/4" knockouts. For installation convenience, four flexible mounting straps are positioned at 90 degree intervals. To facilitate suspended ceiling installation and to distribute the combined speaker and backbox weight to the ceiling grid, the backbox may be used with tile bridge Model LBS4-DX or SS Series channel in 24”, 30”, or 48” lengths (order separately).
