Installation and cabinet guidance

Allow for a 61 mm panel opening, with space behind the speaker for the magnet and terminal connections. Align the fixing holes before drilling. Optional grille: 2312.

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.
