Like the entire Karat line, the new M series speakers feature attractive cabinets with narrow front panels for improved line-source imaging in the midrange and upper frequencies. The three-way speakers use side-firing woofers to avoid excessive front baffle width. Each cabinet is constructed of extensively braced and damped MDF and is highly resistant to resonance. Cabinet finishes are available in graphite and silver lacquer, which is hand applied in numerous layers, as well as real wood veneers of cherry or beech.

Canton's Karat M 20 is a two-way compact model with a single 6-inch woofer and 1-inch tweeter. It is equally suited to use as a stereo pair, or as the front or surround channel in a dedicated multichannel music or theater system.
