Atlantic Technology surprised me in its demo with the high quality sound coming from its IWTS-30, THX certified in-wall speakers. Three of them were used across the front, along with four surrounds and two subwoofers. The IWTS-30 ($1375 each) is a three-way system, and the midrange-tweeter array can rotate 90-degrees when horizontal placement is desired or necessary. The same module also tilts to angle the sound slightly to the left and right, when necessary.
