Installation and cabinet guidance

Allow for a 62 mm panel opening. The round plastic frame is 70 mm in diameter; the mounting depth is 15.6 mm and the unit is 19 mm deep overall including the 3.4 mm flange, with a 32 mm square magnet housing. The frame has no fixing holes, so it is normally bonded or clamped in place; check the method against your enclosure design and keep the clamping even all round.

The IP67 protection applies to the front of the driver only, and only when it is built into a sealed enclosure; the rear is open to the enclosure. Mount on a flat panel with a continuous seal around the frame and protect the rear from water and dust; bonding the driver in and fitting a front cover or grille may be needed to complete the protection. Run the cable so that water cannot track along it into the enclosure, and leave a drip loop where it is exposed. Operating temperature range −40 to 80 °C.

Connect to the two 2.8 x 0.5 mm blade terminals, 12.8 mm apart, with matching push-on connectors and observe polarity. Use an amplifier suitable for the 8 Ω load and keep the drive within the 2 W rating (3 W maximum).
