Installation and cabinet guidance
Allow for a 57 mm panel opening and align the four slotted fixing holes. Seal the mounting joint and protect the rear from moisture: IP64 protection applies to the front when installed in a sealed enclosure. Optional grille: 2203.
Use an amplifier suitable for the 8 Ω load and observe terminal polarity. For a 100 V line system, connect through a suitable line transformer; do not connect the driver directly to the line.
