Point Source In-Ceiling Minimal Appearance Loudspeaker

The Minimal Appearance iSC3 Satellite (and optional SUB1 Subwoofer) in-ceiling solution is designed to provide architecture-friendly, high-resolution playback while matching 3″– 4″ recessed round and square lighting fixtures. The iCS3 spiral Planar Magnetic Driver offers unmatched ultra-wide dispersion, while the SUB1 subwoofer delivers unparalleled output delivering an amazing, yet interior designer appearance. 

Behind the high performance of the iCS3 in-ceiling speaker is a new Spiral Planar Magnetic Driver (SPMD). This engineering breakthrough offers super-wide dispersion down to 900Hz from the SPMD before crossing over to the 4.25″ woofer allowing sound energy to be evenly distributed throughout the listening space without having to use as many speakers as our competitors.
