Definitive Technology DW-MAX SUR Surround In-Wall Speaker

Home theaters with large rooms get an enveloping surround field from the Definitive Technology Dymension DW-MAX SUR, a bipolar in-wall speaker from the premium CI MAX line.

Two 1 in aluminum oxide dome tweeters and two 5.25 in mineral-filled BDSS woofers sit on opposite-facing planes to project sound in more directions, and a three-position switch trims the highs by -2 dB, flat or +2 dB. A paintable magnetic grille and toolless mounting keep installation clean.
