IMPACT series has become well-known for its power to price ratio.  Big power at great value. Customers around the world love their IMPACT series loudspeakers and are proud to use ‘Wharfedale Pro’.

To enhance that brand quality and customer passion, we have made a small cosmetic upgrade to IMPACT.  It now boasts the iconic Wharfedale Pro boomerang logo !

The Impact-X15ML passive floor monitor encapsulates everything Wharfedale Pro stands for – High quality pro audio, at an affordable price. On this occasion we have raised the bar for affordable PA delivering a PA speaker series with a sound and aesthetic comparable to that of a much higher price bracket.

Full range IMPACT
The Impact Series has a desirable high power capacity and clarity. Impact-X15ML is rated at 350W RMS (1400W peak) and the power spans down to a 50Hz low-end.

For high frequency, a 1.75" titanium diaphragm compression driver produces a powerful yet neutral sounding high end.

Both the HF and LF drivers are custom engineered and are acoustically matched to the extremely durable MDF cabinet.
90° x 60° Elliptical Waveguide
For wide and smooth coverage a 90° x 60° elliptical waveguide has been selected.

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.
Built to take an IMPACT
The Impact-X15ML is ready for whatever life throws at it.

The strong MDF cabinet is covered in a textured black paint to give a durable yet stylish finish, which brings a professional look to any sound reinforcement environment.

The finish is extremely hard wearing and is leagues above any other carpet covered cabinet in the same price point.
IRIS X driver engineering
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.
