The iC4 offers full range response and features NHT's patented 3-tweeter array technology, providing flat frequency response up to 60 degrees off axis. The iC4 features an aluminum 8" long-throw woofer and three aluminum 1" tweeters. It combines the same broad dispersion and pristine midrange response as the iC3 with higher output and bass response to an amazing 40Hz. The iC4 is ideal for surround channels and other critical listening room installations. The iC4 can be installed in new construction or retro-fit into existing construction and is available in a paintable matt white finish.
