Installation and cabinet guidance
Allow for a 114 mm panel opening and 30.5 mm speaker depth, plus space for the terminals and wiring. Match the fixing positions before drilling. Optional grille: FR 12, part 2062.
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.
