The slender Radius 225 is even slimmer than its predecessor. At just 65mm in depth, the 225 is the perfect match with today's ultra-thin displays. Use it as a centre channel or main speaker: its acoustic design of twin 4” (100mm) C-CAM® mid/bass drivers astride a 1” (25mm) C-CAM tweeter delivers superb accuracy from horizontal and vertical positions. Extend bass further by adding the awesome 380 or 390 subs for breathtaking full-range AV or stereo sound. The new 225 may be thinner physically, but its performance will fill the air with exhilarating audio wall-to-wall.
