The IW D7 is a high performance, in-wall LCR, based on our highly regarded D7 tower. The same components are mounted in a fully enclosed, easy to mount aluminum enclosure, giving you near freestanding tower performance from an in-wall solution. IW D7 is a 6.5-inch, D’Appolito Array, designed by Snell chief engineer, Joe D’Appolito. In 1990, Snell developed the first “back-boxed” in-walls designed to mount flush in typical 2” x 4” walls. The evolution of this technique corrects for the problems associated with all in-wall installations. The fully enclosed cabinet defines bass performance and reduces sound transfer to adjacent rooms, while the non-plastic, three part baffle quiets cabinet resonance, which in turn reduces vibration to the wall materials. The twin 6.5-inch long throw woofers provide extended bass and plenty of output, and the 1-inch low-resonance, silk dome tweeter enables a large sweet spot for better stereo imaging. The IW D7 is capable of tremendous impact, and realistic sound staging. It is the perfect speaker for any high performance music or video system. It is living proof that sound quality without compromise can be delivered unobtrusively .
