Constructed from 18mm plywood and covered in the highest quality Rhino Rock paint, the new Delta X218B is instantly recognisable by its engraved iconic Wharfedale Pro ‘boomerang’ logo on its surface. The fresh cosmetic design however is not the only improvement the engineering team have made in creating the Delta X series.
Internally Delta X models have a new crossover design and construction.  Using new component positioning and bracing, the sensitive crossover electronics have been re-engineered to improve long term performance and reliability – even at the highest of volumes.

With rear panel switching, Delta X218 has Discrete and Parallel modes of operation.  This allows to address each LF driver individually, or as a pair. This routing flexibility allows for Delta X systems to be refined using multiple amplifiers and external crossovers.

Custom Wharfedale Pro transducers have been selected. High output, low physical distortion cast frame woofers deliver unparalleled low frequency response. With the exception of the Delta X10, 2” titanium compression drivers are coupled to 90°x45° elliptical waveguides for impressive output level and smooth HF dispersion.

With a full lineup of 9 new models, ranging from the 300w RMS Delta X10 to the 1600w RMS Dual Chamber 2 x 18” Delta X218 subwoofer, Delta X models are perfect for fixed installation and touring applications.
