- EN54-24 certified for use in voice alarm systems
– Weather resistant, environmental performance to level IP56
– 12AV 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 WR-6412 employs a 12AV woofer for low frequency reproduction. A M-75 compression driver with 3″ titanium diaphragm attached to a 60º x 40º rotatable horn provides exceptional high frequency reproduction. The rugged birch plywood cabinet construction is available in black, white or military grey depending on the finish.

The WR-6412 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.
