Delta X builds on the global success of the Wharfedale Pro Delta series.
Constructed from 15mm plywood and covered in the highest quality Rhino Rock paint, the new Delta X18B is instantly recognisable by the engraved iconic Wharfedale Pro boomerang logo on its cabinet. The fresh cosmetic design however is not the only improvement the engineering team have made.
Internally Delta X also has 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, the full range models of Delta X can operate in either Bi-Amp or Passive modes. This routing flexibility allows for Delta X systems to be refined using multiple amplifiers and external crossovers.
Custom Wharfedale Pro transducers have also 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 90x45 elliptical waveguides for impressive output level and smooth HF dispersion.
With a full line-up 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.
