The IWTS-14 SR are called surround speakers because that's what they do. They surround you with the environmental sounds of the scene taking place on the screen. No matter whether in Dolby Surround®, Dolby Digital®, DTS®, or any other format, the surround speakers are there to deliver non-localizable environmental sonic cues.
These horizontally-mounted speakers offer a unique combination of benefits. They deliver true Dipole surround performance, and yet, thanks to it minimum footprint design, fit easily into a standard 2 x 4 studded wall! Each speaker consists of two sets of matched drivers --in essence, two speaker systems. In Dipole mode these two systems operate "out of phase" with each other. The speaker's sound radiation pattern is similar to an infinity symbol, sweeping along the wall to each side. There's a distinct null or "dead zone" centered directly in front of the speaker which is in turn centered on the seating area. When properly placed and balanced, this creates a large, diffuse, non-localizable, and enveloping sound field that draws you into the action. Should you have an installation in which Dipole operation might be less than optimal, the speakers can easily be switched to Bipole operation.
