Delta X218B

Refinement in detail

Delta X builds on the global success of the Wharfedale Pro Delta series.
 
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.

New crossover design
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.
18mm Russian Birch Plywood Construction
Delta X218B is made of premium Russian birch plywood.

It is even more dense than MDF and creates an extremely strong and durable cabinet. Although not recommended, birch plywood is more tolerant in damp conditions.

During construction, it is harder to cut but holds screws better than particle board or MDF. This makes it ideal for flagship professional audio loudspeakers which are to be used in extreme and critical environments.
Solid as a rock
As with all Wharfedale Pro PA systems, years of expertise is behind a loudspeaker built to last, with thanks to our high standards of quality control.

The Delta X series are coated in the highest quality Rhino Rock paint finish - a chip resistant texture with a professional, discrete aesthetic whilst being prepared for the rigours of life on the road.
Dual chamber, dual 18"
The two 18” Wharfedale Pro LF transducers with massive 4” voice coils work together to deliver up to 138dB Max SPL.

Using cast frame aluminium baskets, any mechanical distortion is dramatically reduced ensuring smooth, accurate and honest reproduction.
Huge voice coils
The huge 4" voice coils ensures massive power handling.

The Delta X218B can handle peaks of up to 6400w and programme material averaging 3200w.

These custom Wharfedale Pro drivers are efficient and powerful - delivering the sub-bass punch needed for larger gigs and impressive installations.
