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

Single Unit

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)

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



A Bathroom remodel Fremont project can be a big endeavor. You’ll need to look at changing the fixtures, the flooring, and possibly even the design and structure of the walls.

These speakers are very impressive. I bought them a few months ago when I was trying to update my home's entertainment system and WOW. The sound quality is extremely impressive. Great highs, lows, and mids.
