Full range models feature a 90° x 60° Elliptical Waveguide

In real-world terms this means that the higher frequencies can be heard with definition at 90° in the horizontal plane, and 60° in the vertical.

All full range models in the Impact-X series use this same elliptical waveguide design which makes for controllable coverage when using multiple Impact series loudspeakers.

The coil size and electrical sensitivity of a loudspeaker transducer is critical to its performance.  Impact-X loudspeakers now include our proprietary IRIS X design which delivers Increased coil Radius and Increased electrical Sensitivity.  The radius of the coil ensures smooth heat dissipation during prolonged high volume use, while the increased electrical sensitivity ensures that the transducer converts as much electrical power into sound output as the laws of physics allow.  

A hot transducer wastes energy, risks damage and distorts.  IRIS X reduces this through improved heat dissipation and improved efficiency.

In real-world terms, IRIS X transducers deliver higher SPL with less distortion.  They lead the market with specifications and are designed and built entirely within Wharfedale Pro.
