The MR835 Features a 15" low frequency transducer, 8" cone midrange, and a pure titanium compression driver mounted to a Flat-Front Bi-Radial horn. Ideal for DJ music playback, on stage monitors, or general sound reinforcement. This pair of MR835s came from Alloy Music, the JBL restoration guys, and were carefully tested and given the green light. Comes with receipt for $660.oo from Alloy, along with 50 foot cables I bought separately. Quick sale, raising cash for school. These bad boys rock.
