The iC4-ARC is NHT's super-premium 8" woofer in-ceiling speaker. Apart from the 8" woofer, it is exactly the same as the ic3-ARC. 

Sold as single units rather than speaker pairs, iC4-ARC in-ceiling speakers are ideally used in premium home theaters and certainly in concert with NHT's premium Classic Line of in-room speakers. iC4-ARCs can also be used in any situation where the very best sound reproduction is desired with almost no physical presence in the room. Weather and moisture resistant materials make the iC4-ARC suitable for outdoor eves, covered patios, and master bathrooms as well. Like all the products in the Architect In Ceiling series, the iC4-ARC features NHT's new micro-perforated, bezel-less grill that attaches magnetically and reduces the installed footprint by almost 15% over its predecessor.

Don't forget the companion iCB8 pre-construction bracket (sold individually). Note: this bracket IS NOT used for retrofit application (existing structures).
