Installation and cabinet guidance

Allow for a 100 mm panel opening and align the four mounting slots before drilling. Use connectors that fit the 5.2 × 0.5 mm positive and 2.8 × 0.5 mm negative terminals, leaving room behind them for the wiring. Optional grilles: 4642, 4640, 4670 and 4744.

Use an amplifier suitable for the 4 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.
