Perhaps one of the most intricate passive loudspeakers ever built, the M5 has over 300 individual elements. Retaining our revolutionary ‘tension-coupling’ mechanism, and combining our signature 17-ply Baltic Birch cabinet with a 200 lb. slab of 6061-T aircraft grade aluminum machined into 73 lb. vertically convex baffle, we’ve created the ideal housing for our massive new bass drivers. Intended to completely change the limits of loudspeaker performance, the 2009 innovation award winning M5 is the most thoroughly developed and technologically ambitious loudspeaker we’ve built to date.
