PhaseTech CS-8R 8" Coaxial In-Ceiling Speaker
The PhaseTech CS-8R is an 8" coaxial in-ceiling speaker designed to deliver exceptional sound quality for home theaters, multi-room audio systems, or commercial installations. With premium components and smart engineering, it offers high-end performance in a discreet, ceiling-mounted form factor.
Featuring an 8" polypropylene woofer with a butyl rubber surround and a 0.75" variable-axis soft dome tweeter in an offset configuration, the CS-8R ensures wide dispersion, smooth frequency response, and excellent clarity. The adjustable tweeter allows you to direct high frequencies toward the listening area, even when placement is less than ideal.
A magnetic, ultra-thin micro-flange grille (round) is included, blending seamlessly into ceilings for a clean look. Optional accessories include a square grille (CI7X-SG) and a pre-construction bracket (AC-CS-8R-PCB). All grilles are paintable, rust-resistant, and built for long-lasting performance.
