Constructed from 15mm plywood and covered in the highest quality Rhino Rock paint, the Wharfedale Pro Delta 15" 500W 2-Way Passive Speaker 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 X15 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, Delta X15 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 90°x45° elliptical waveguides for impressive output level and smooth HF dispersion.
In BI-AMP mode, two power amplifier channels can be used, one for each section of the loudspeaker (HF compression driver and LF transducers). DSP (Digital signal processing) is used to separate the audio signal into specific frequency bands for each amplifier channel, powering only the corresponding driver section inside the loudspeaker. This gives you the advantage of being able to select the optimal power specifications and use independent limiter and EQ settings for each driver, resulting in more granular system control and a safer, more efficient, and protected system.
In PASSIVE mode, a single amplifier channel can be used to power all drivers inside the loudspeaker. The full frequency range is put into the loudspeaker and the loudspeakers’ internal passive 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 channel is powering both the HF compression driver and the LF transducers. The internal crossover takes care of both the frequency and power separation.
