The iW4-ARC is our powerhouse architectural product. In a good installation, you might think you were listening to a pair of Classic Three’s on stands. Outrageous dynamics, terrific bass, high output are present in the iW4-ARC with no loss in detail thanks to two 5.25” anodized aluminum cone woofers, a 2” anodized aluminum dome midrange, and a .75” anodized aluminum dome tweeter. This Tweeter-Midrange module is the same module used in all 3-way Classic series designs. The advantage of a dual-woofer 3-way design is low distortion and wide dispersion, and enlarges the sweet spot for an unrivaled listening experience from an in-wall speaker. The iiW4-ARC body features a new material that eliminates spurious resonances from interfering with proper sound reproduction. Lastly, the grill is easily detachable since it is magnetic and the IW4-ARC is easily installed and can be mounted vertically or horizontally in the wall. 

All in all, the iW4-ARC is the perfect in-wall home theater system speaker.

(iW4's can also be used in-ceiling though the dispersion will not be as ideal as the ic4)

Such amazing sound

iW4-ARC - 3-Way In-Wall Home Theater Speaker

I was on a roofing job not long ago and while we were replacing the roof we could hear everything that was playing in his basement. The sound from this was so pure that we had to ask him for the make and model so that we could put it in our house as well.
