About the DM40
The Definitive Technology Dymension DM40 is a slim floor-standing tower speaker designed for home theater and stereo music, delivering spacious, three-dimensional sound through its fully balanced, adjustable bipolar driver array with front- and rear-firing drivers. It includes dual 1-inch aluminum oxide dome tweeters for crisp highs and four 4.5-inch composite polymer woofers with long-throw surrounds for detailed midrange and robust bass. The ported enclosure optimizes bass response, and a rear tweeter switch (0dB full-bipolar or -6dB forward-focused) allows customization for room placement. Timbre-matched with other Definitive Technology speakers, it's Dolby Atmos/DTS:X ready with optional height modules, and includes spikes and glides for versatile setup. Sold individually.
