About Lowell Manufacturing BME87

An essential addition to any professional audio setup, the BME87 Steel Backbox and Mounting Ring for 8" Speaker, measuring 10" in diameter and 6.69" in depth, offers a robust and efficient solution for speaker installation. This kit is designed to facilitate a blind-mount enclosure, ideal for installations in drywall or plaster ceilings where above-ceiling access is limited.

Constructed from heavy gauge steel, the backbox is welded and unitized, ensuring durability and longevity. It features a foam pad at the rear, specifically designed to minimize acoustic and metallic resonance, thereby enhancing the overall sound quality.

The cubic volume of the backbox is engineered to allow your 8" speaker to operate at an optimal loading level, significantly improving the low-frequency response. This feature makes it an excellent choice for those seeking to achieve superior sound performance.

The BME87 kit is equipped with four combination 1/2" - 3/4" conduit knockouts and four 1/2" wire knockouts, providing ample options for wiring and installation. Inside the enclosure, two welded brackets are designed to mount a range of torsion grilles, offering a clean, hardware-free look.

Additionally, the flange features tinnerman clips that allow 8-32 screws to mount a standard 8" grille, ensuring a secure and stable setup. The entire unit is finished in a sleek black powder epoxy paint, adding a touch of elegance to its robust functionality.

In summary, the BME87 Steel Backbox and Mounting Ring for 8" Speaker is a versatile, durable, and efficient solution for enhancing your audio experience, making it a valuable addition to any professional or home audio setup.
