- EN54-24 certified for use in voice alarm systems
– Weather resistant, environmental performance to level IP56
– 15AV woofer with 3” voice coil
– M-75 1,5″ compression driver
– Rotatable 60º x 40º horn design
– Two exposure ratings: CX (covered exposure) and DX (direct exposure).

The WR6415 employs a 15AV woofer for low frequency reproduction. A M-75 compression driver with 3″  titanium diaphragm attached to a 60º x 40º rotatable horn provides brilliant highs. The rugged birch plywood cabinet construction is available in black, white or military grey, depending on the finish.

The WR 6415 offers two exposure ratings: CX (covered exposure) for applications where cabinets are covered or protected, and DX (direct exposure) where cabinets are unprotected and directly exposed to the environment. The CX versions are protected with a thick ISO-flex polyurea coating on the exterior surface. The DX versions augment the protection rating by employing a fiberglass exterior. Stainless steel fittings and mounting hardware are offered on both versions.

Nominal Power based on a 100 h test using a 6dB crest factor pink noise signal filtered according to the IEC 60268-1:1985 norm and band-pass filtered with Butterworth 24dB/Oct filters from 89 Hz to 11,2 kHz.

Sensitivity and Max SPL measured using a 6 dB crest factor pink noise, averaged from 100 Hz to 10 kHz in 1/3 Octave bands.

Coverage measured from 500 Hz to 4 kHz in Octave bands.

Measured SPL obtained by integration over a period of at least 30 s.
