The IWTS-14 and 30 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!
