Installation and cabinet guidance

Allow for a 31.5 mm opening, 32 mm square frame and 24.5 mm fixing pitch. Leave room for the 15 mm overall depth and solder lugs. Keep screw heads and the front grille clear of the surround.

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 8 Ω load and follow the polarity marks. Solder without prolonged heating, insulate the joints and secure the wires so they cannot touch the cone or pull on the lugs.

Test the driver in the intended enclosure before fixing the cabinet design. Keep the rear acoustic space clear and check low-frequency cone travel at the intended operating level; a small driver’s usable bass depends on the enclosure and required output.
