Professional Partners Ltd. have redesigned the BackStopp acoustic-enhancing insert.
The new design is a low-profile, sound absorbent foam with a sculpted surface that helps to reduce any rear-directed sound wave collisions by absorbing excess sound energy within the BackBoxx. BackStopp is an ideal solution to in-wall and in-ceiling speakers that may feature midrange harshness.
The new model is Class 1 fire resistant (ASTM E 84), resistant to fungus and microbial growth. Sound Absorption Coefficients, NRC: 0.50 (per ASTM C423•90a mounting type A). Installation is easy with the peel-back adhesive backing.
Professional Partners Ltd. is the manufacturer of the patented BackBoxx speaker enclosure and other installation solutions for audio video installers. Professional Partners products are made in the USA.
