Installation and cabinet guidance

Allow for a 76 mm panel opening and a 78.5 mm square frame with four fixing holes. Leave about 47 mm behind the panel for the shielded magnet assembly, terminals and wiring.

Use push-on connectors that fit the 4.8 x 0.8 mm positive and 2.8 x 0.8 mm negative blade terminals, observe polarity and use an amplifier suitable for the 8 Ω load.

A matching 8 cm protective grille is available as an accessory; check its fixing pattern against the frame before drilling.
