Installation and cabinet guidance

Allow for a 43 × 82 mm oval opening, 50 × 90.5 mm frame and 28.5 mm depth, plus wiring clearance. Check connector fit on the supplied driver before ordering terminals. Confirm impedance and fixing positions when replacing an existing speaker.

Mount on a rigid panel with a continuous seal around the frame to prevent air leaks and rattles. Keep the cone and surround clear of the grille and internal parts.

Use an amplifier suitable for the 4 Ω load and follow the polarity marks. Check blade width and thickness before choosing connectors, insulate the connections and secure the wiring clear of the moving parts.

Use this impedance version’s enclosure parameters when developing a cabinet, and test the response at the intended listening level. Allow for the volume occupied by the driver and keep damping material clear of the cone and terminals.
