Installation and cabinet guidance

Allow for a 61 mm panel opening, 34.6 mm depth and additional space for the connections. Protect the rear and terminals from moisture. Optional grille: 2312.

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.
