SR-TW6.5LS

6.5″ coaxial ceiling speaker with transformer — four power taps, 150° conical coverage.

A commercial ceiling loudspeaker for large-scale PA installation. The two-way coaxial driver pairs a polypropylene cone and butyl rubber surround with a Kapton voice-coil former, high-temperature voice coil and aluminium coupling ring for low distortion and extended HF. Four power tappings at 100V or 70V — or direct 8Ω operation — make it equally at home in schools, restaurants, hotels, stations and airports.
