Wharfedale Pro Delta 15 Passive Speaker

WHARFEDALE DELTA 15 PASSIVE SPEAKER 

The Delta 15 uses a high output, low distortion 15” cast frame woofer with a 3” voice coil. A 2” titanium compression driver is coupled to 90°x45° elliptical waveguide for smooth HF dispersion. 

Comprehensive rigging points are provided for use in flown applications, so Delta 15 is equally at home in a wide variety of fixed installation and touring applications. Rhino Rock™, our new texturised composite finish is used in all models. This new finish provides the great look of a painted finish with the durability of a carpet covered enclosure giving you the best of both worlds. The Delta 15 is constructed from plywood and features dual angle pole mounts to ensure that your sound is aimed directly at the audience, not at the ceiling.
