It delivers up to 109 dB continuous and 115 dB peak SPL at 1 meter, with transformer power taps to 60W and a 120W 16Ω bypass rating for high-SPL distributed audio applications. The three-point double-stepped long-travel dog-ear blind mount system allows installation without ceiling access from above, using C-ring and rails hardware.\u003c\/p\u003e\u003ch2\u003eProduct Description\u003c\/h2\u003e\u003cp\u003eSold as a matched pair. The AD-C6T-HP targets demanding distributed audio applications where a 4.5-inch speaker lacks the headroom or low-frequency extension required. The 6.5-inch paper cone woofer uses a 1.75-inch voice coil on a ferrite magnet structure, providing the power handling needed for 60W transformer operation and 120W in 16Ω bypass mode. A 1.4-inch kapton dome compression tweeter handles high-frequency reproduction above the 2.6 kHz crossover point, extending the frequency range to 20 kHz. Frequency extension reaches 58 Hz (-10 dB), providing usable bass response for background music and moderate-SPL speech-plus-music applications. The 120° conical coverage pattern (-6 dB) with a directivity index of 5.6 dB provides focused energy delivery to the listening plane in rooms with acoustically treated or hard ceilings. The blind mount system is a practical installation feature: the three dog-ear clamps engage the ceiling from below without requiring personnel in the plenum, which simplifies retrofits in occupied buildings and reduces installation labor. Transformer tap selection — 7.5, 15, 30, and 60W at 70V; 15, 30, and 60W at 100V — allows the system designer to match per-speaker power to coverage zone requirements within a distributed audio system. The 4-pin Euroblock input with parallel output supports daisy-chain wiring. The minimum impedance of 15.4Ω at 281 Hz is within specifications for standard 70V\/100V distributed amplifiers. The powder-coated steel backcan provides structural integrity and thermal management for sustained high-power operation.\u003c\/p\u003e\u003ch2\u003eKey
