SoundTube CS-8R 8-Inch 2-way In-Ceiling Speaker, Single Unit or Master Pack
The PhaseTech CS-8R is a professional-grade 8" coaxial in-ceiling speaker engineered for outstanding reproduction of movies, music, and multi-channel audio systems. Its unobtrusive, paintable magnetic micro-flange grille and low-profile bezel blend seamlessly into any ceiling, while the pivoting .75" soft dome tweeter ensures precise off-axis coverage.
Constructed with an 8" polypropylene cone woofer featuring a butyl rubber surround, the CS-8R delivers robust mid-bass performance down to 42 Hz. The infinite baffle enclosure design and 8 Ω nominal impedance allow flexible installation paired with a variety of amplifiers (5–120 W). Available as a single unit or as a CS-8R Master Pack of 12 units for large-scale deployments.
