Wharfedale Delta X15 15" 2-way 500W RMS, 8 Ohm speaker, Rhino rock finish

The Delta X15 is a 15-inch two-way passive loudspeaker rated at 500 W RMS (1000 W programme, 2000 W peak) into 8 ohms, pairing a 15-inch cast-frame woofer with a 3-inch voice coil and a 2-inch titanium compression driver for a full-range response of roughly 50 Hz to 20 kHz and up to 131 dB max SPL.

The cabinet is built from 15 mm birch plywood, finished in tough-tone paint and protected by a 1.5 mm steel grille for durability on the road. A rear-panel mode switch lets it run as a standard full-range passive speaker or in bi-amp mode, driving the low and high frequencies from separate amplifier channels.
