Installation and cabinet guidance
Use the drawing to check the mounting profile, spring-contact positions and working clearance.
Design the matching contacts and retention so contact pressure is maintained without loading the diaphragm. Use an 8 Ω-compatible amplifier.
IP65 applies to the front with a sealed mounting joint. Protect the contacts and rear of the speaker within the equipment.
