Installation and cabinet guidance

Allow for a 73 mm panel opening and a 77.5 mm square frame with four fixing holes. Leave about 48 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.

In a two-way system, add a suitable crossover for the tweeter and keep the cabinet sealed around the frame to avoid leaks and rattles.
