iC3-ARC In-Ceiling Speaker

Single Unit

The iC3-ARC is a super-premium, 3rd generation high-end in-ceiling speaker utilizing a number of unique technologies that work together to deliver an audio performance well beyond your expectations. Sold as single units rather than speaker pairs, iC3-ARC in-ceiling speakers are ideally used for premium multi-room audio, as home theater speakers for any channel, in office commercial venues or anywhere you want affordable high-end sound hidden from view. Weather and moisture resistant materials make the iC3-ARC suitable for outdoor eves, covered patios, and master bathrooms as well. The iC3-ARC also features a redesigned micro-perforated, bezel-less grill that attaches magnetically and reduces the installed footprint by almost 10% over its predecessor.

The iC3-ARC in-ceiling speaker technologies include the premium anodized aluminum version NHT’s proprietary 3-tweeter array to deliver the widest, sound field currently available from any ceiling mount speaker. This patented array is nested in the center of a custom designed, long-throw, 6.5” aluminum-cone woofer. These components are then assembled into the remarkable new Anti-Resonant Casting or ARC “monocoque” chassis and 3-tweeter array sub-assembly to provide unprecedented strength and a lifetime of durability while acoustically reducing frame vibrations (distortions) to inaudible levels. Just before we install the speaker components, a smooth rubberized paint finish process is applied to the chassis that works together with ARC to help damp surface vibrations that can further blur the sound.

The iC3-ARC is also an integrated, serviceable design and features a bezel-less grill/frame design (no exposed frame lip or wide trim ring around the grill) and the beautiful micro-perforated grill attaches and centers itself magnetically! Simply said, with over 25 years of acoustic design under our belt, the iC3-ARC is simply NHT’s best mid-size ceiling mount speaker to date.

Be sure to use the companion iCB6 pre-construction bracket for exposed ceiling joints. Note: this bracket IS NOT used for retrofit application (i.e. existing structures).

Great Sound Yet Unseen


During a recent remodel of my family room, the speakers were upgraded to NHT IC3's. I purchased 4 of them. I could not be happier with the sound quality and imaging especially since they are ceiling mounted. I retained my existing nht center and amplified sub. Hope to install dual in wall subs soon. I have long been impressed with NHT... My first speakers were original model ones in oiled oak finish purchased in the mid 80's. Bottom line... For music or home theater, these speakers are most satisfying.

Absolute Clarity with solid low end !!!


We had these speakers installed in our new house in the kitchen and wired to the ent centre in the other room...I cannot relay how clear and precise these speakers are. I am so happy we moved to the IC3's.Also, being in the roof of our kitchen over the centre island, the tri-tweets really throw the sound around the room nicely. Highly, Highly, Recommended !!!

Super Product


The aluminum dome tweeters are certainly the best feature. The clarity is unbelievable. Most in-ceiling speakers produce a a "flash light"€ image, where these speakers are like "€œhigh beams"€.
