Installation and cabinet guidance
Allow for a 116 mm panel opening and match the mounting slots before drilling. Leave room behind the speaker for the magnet, terminals and wiring. Optional grilles: 4643 and 4667.
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.
