X15 Passive Loudspeaker Gives You Reason to Be Cheerful

The New 3-way Passive Loudspeaker Give Reasons to be cheerful, 1…2….3

A THREE-WAY SYSTEM – with matching subs.

Built exclusively to deliver incredible sonic definition at high volumes, the Reason-X15 series brings new concepts and new qualities to become the premium pro audio loudspeaker series in the Wharfedale Pro portfolio.

The full range models X15 feature an all-new Polyethylene flat diaphragm neodymium HF. This highly engineered Z38 HF compression driver brings extreme HF clarity. Enormous cooling fins disperse the heat generated and the unique 1.5-inch ring-shaped polyethylene flat diaphragm delivers a precious feeling of space and air to high frequencies.

The 100° x 70° waveguide is also rotatable, making Reason-X15 suitable for high-quality installations and touring.

The mid-range comes from a custom Wharfedale Pro 8” driver with an aluminium basket and ferrite magnet and it delivers a warmth and clarity. Meanwhile, the LF driver boasts a 3.0” voice coil and large φ190mm ferrite magnet. This 3-way combination gives the Reason series full range models a frequency response and audio definition that simply has to be experienced.

The series is completed by 2 subwoofers. A single 18” and a floor destroying 148dB Max SPL dual 18”. New LF drivers have been created which feature NOMEX spiders for extreme suspension and durability. 4.0” voice coils and a newly designed aluminium basket make these LF transducers impossible to describe in words – they need listening to instead!

All models are constructed of premium baltic birch and use thick steel front grilles for extreme durability.

Updated mute glue is used. This bonding can eliminate brittle cracking and reduces harmonic distortion.
112 g Membrane.
The Reason-X subwoofer driver has a heavier membrane which can withstand more power without breaking.
31 mm voice coil cavity.
A larger internal cavity for the coil windings allows Reason-X to have lower response by 5 Hz.
