Phase Tech CS-6R 6.5" 2-way In-Ceiling Speaker (PAIR)

PhaseTech CS-6R 6.5" Coaxial In-Ceiling Speaker

The PhaseTech CS-6R is a high-performance 6.5” coaxial in-ceiling speaker, engineered for exceptional audio in home theater and whole-house distributed sound systems. Designed to deliver premium acoustics, even in less-than-ideal placements, the CS-6R features a 0.75” variable-axis soft dome tweeter that can be aimed toward the listening area for optimal high-frequency clarity.

Its 6.5” polypropylene woofer with a butyl rubber surround ensures deep, balanced bass and smooth mids. The offset tweeter design, combined with PhaseTech’s Absolute Phase™ crossover network and auto-reset overload protection, delivers accurate and consistent sound in any room.

A round, ultra-thin magnetic micro-flange grille comes standard and blends seamlessly into ceilings. A square grille (CI6XSG) and rough-in bracket (RB-14) are available as optional accessories. All grilles are paintable and built to resist rust and corrosion—perfect for long-term reliability and aesthetic integration.
