iC2-ARC In-Ceiling Speaker The iC2-ARC is a modern, 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, iC2-ARC in-ceiling speakers can ideally be used for 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 iC2-ARC suitable for outdoor eves, covered patios, and master bathrooms as well. The iC2-ARC features a beautiful, redesigned micro-perforated, bezel-less grill that attaches magnetically and reduces the installed footprint by almost 10% over its predecessor. Two professional grade, gold plated spring posts.View larger Anti-Resonant Casting (ARC) Virtually Eliminates Vibration Distortion The iC2-ARC ceiling speaker technologies include NHT's proprietary 3-tweeter array to deliver the widest, sound field currently available in any ceiling mount speaker. The 3-tweeter array is nested in the center of a long-throw 6.5" polypropylene 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. Attractive, Bezel-less Design Just before NHT installs 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 blur the sound. The iC2-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 the belt, the iC2-ARC is NHT's best mid-size ceiling mount speaker to date. Pair with iCB6 Pre-Construction Brackets (sold separately) For new construction (exposed ceilings joists), be sure to use the companion iCB6 pre-construction bracket (sold individually). Please note the iCB6 is not used for retrofit application (existing structures). NHT's 3-tweeter array delivers the widest sound field available in any ceiling mount speaker.
