Product details
Eight-inch SSI flexibility
Flip between 2 and 4 ohms without dual-coil wiring puzzles. Useful when space limits you to a compact eight but you still want Stadium power handling. Confirm sealed or ported enclosure volume against the published Thiele/Small recommendations before cutting wood. Use oxygen-free speaker wire of adequate gauge for the run length, and double-check SSI or impedance switch position before powering the amp.
Aero-cooled reliability
A 2-inch aero-cooled voice coil and premium push terminals support long high-output sessions. Confirm sealed or ported enclosure volume against the published Thiele/Small recommendations before cutting wood. Use oxygen-free speaker wire of adequate gauge for the run length, and double-check SSI or impedance switch position before powering the amp.
Enclosure planning
Cutout about 7-1/3" with 5-1/3" depth. Pair with an amp near 400 W RMS continuous. Confirm sealed or ported enclosure volume against the published Thiele/Small recommendations before cutting wood. Use oxygen-free speaker wire of adequate gauge for the run length, and double-check SSI or impedance switch position before powering the amp.
