Installation and cabinet guidance

Use the bracket and drawing to allow for the 133 mm horn mouth and 99 mm body depth. Fix it securely and leave enough clearance to adjust the aim and route the lead.

Connect the ferruled 0.5 m cable to a suitable 8 Ω amplifier, following the product polarity markings. This is the 8 Ω model; it has no stated 100 V transformer connection.

Protect and strain-relieve the cable joint. Keep the enclosure and cable-entry seals intact to retain the IP66/IP67 protection of the horn.
