BIRCH PLYWOOD

All Delta-X models use premium Baltic birch plywood construction.

Not only does this create a solid and durable cabinet, but it also contributes to the overall sound and character.

Delta-X is also covered in our most durable and hard wearing Rhino Rock paint finish. This ensures that a Delta-X will always look as good as the day you unboxed it.

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.

ROUTED LOGO

Delta-X features a routed Wharfedale Pro logo.

It is a logo to be proud of. A logo that lets your audience know that the sound of your even will be of the highest possible quality.

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.

BI-AMP & PASSIVE MODES

In BI-AMP mode, two power amplifiers can be used. This gives you the advantage of being able to select the best power amplifier specifications for each driver inside the loudspeaker. In a BI-AMP configuration, an external crossover is used to separate the frequencies and this splits the signal to the dedicated LF amplifier and the HF amplifier. This way, each amplifier is only working on the given frequency range and, in turn, is powering the corresponding driver inside the loudspeaker.

In PASSIVE mode, a single amplifier can be used to power all drivers inside the loudspeaker. The full frequency range is put into the loudspeaker and the loudspeakers’ internal crossover separates the frequencies, delivering the right frequencies to the right driver. In the example of a 2-way passive loudspeaker, this means that the single amplifier is powering both the HF compression driver and the LF transducer. The internal crossover takes care of both the frequency and power separation.
