Phase Tech CI7.3X 8" 3-way Ceiling Speaker

PhaseTech CI7.3X Ceiling Speaker – Premium 3-Way In-Ceiling Audio Performance

The PhaseTech CI7.3X is a high-performance 8” 3-way in-ceiling speaker designed for immersive home theater and distributed audio applications. Engineered for clarity, power, and precision, the CI7.3X features a 1” variable-axis tweeter that allows high frequencies to be aimed directly at the listening area — ideal for vaulted ceilings or acoustically challenging rooms.

A +/- 3dB switch lets you fine-tune the tweeter’s output to suit your room’s acoustics, while the offset tweeter design improves imaging and reduces diffraction. The speaker includes a round magnetic micro-flange grille, with an optional square grille (CI7XSG) available for alternate aesthetics. All grilles are paintable, rust-resistant, and corrosion-resistant.

With PhaseTech’s Absolute Phase™ crossover network, auto-reset overload protection, and limited lifetime warranty, the CI7.3X offers outstanding reliability, build quality, and sonic performance — making it a top-tier choice for whole-home audio and high-end theater installations.
