Lowell 8A50-T870
8" Coaxial Driver with 70V Transformer

OUR PART #  8A50-T870

Lowell's 8A50-T870, an 8"coaxial driver, is the flagship of their A-series and represents a performance upgrade over standard commercial coaxial drivers — with greater power handling, lower distortion, and smoother musical sound. It features an 8" 50W coaxial driver with 20 oz. LF magnet coupled with 1.4" copper voice coil drive, a polyproylene cone with half-roll rubber surround for long cone travel and good edge damping. Its post-mounted tweeter is a 1" balanced-drive dome protected by Ferrofluid and a first-order high-pass filter. The speaker frame is stamped 20-ga. steel with black enamel finish and zinc plated backplate. It's engineered for very high quality music and paging uses, especially in large venues like restaurants, retail stores, hotel lobbies, and similar locations where a key part of customer satisfaction is the listening experience.
