The M-80 in-wall speakers offer greater bass output than the M-50 and M-60 In-wall speakers. They feature 1" high power handling soft dome tweeters and 8" poly/graphite woofers. Self resetting thermal cut-offs protect them from over-load. Metal mounting brackets are included for post-construction. Optional M-8R rough-in-kits are available for pre-construction. BIC models that match well with the M-80's are DV62CLR-S (Center Speaker), M-SR8 (Ceiling Speakers), and DV84 (Tower Speakers). M-80 In-walls can be painted to match your decor. Ideal for use with ALL surround and music formats.
