PhaseTech CI820 Ceiling Speaker in White

8 inch Coax In-Ceiling Speaker with Integrated Metal Backcan and Bypassable 70/100V Transformer. The CI820 speaker has an integrated steel backcan and ported design for enhanced bass response with its 1 inch soft dome tweeter and 8 inch polypropylene woofer with butyl rubber surrounds. If 25/70.7/100V audio distribution is a preference, the CI820 comes with an integrated multi-tap transformer. All mounting hardware is included with each speaker and features Speedwing technology to ensure a fit in any drywall or drop-tile application. Tightening two screws locks the CI820 into place, creating an incredibly easy install. Incorporates a painted steel grille for lasted durability.
