The driver inside the Reason-X subwoofer has some very special features.
∮102.6 diameter voice coil.
(Thats OVER 4.0″ but we say 4.0″ because of number rounding)
Double-layer spider bonding.
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.
6.2 ohm impedance.
The impedance peak is higher in the Reason-X driver at 35 Hz. This results in superior low end strength.


The full range models (X12 and 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.

Advanced HF compression driver technology which deliveries breathtaking results.


A handy feature is the rotatable waveguide which allows Reason-X full range models to be used in the vertical or horizontal plane.

100° x 70° 


70° x 100° – the Horizontal and Vertical dispersion can easily be changed.



With dedicated drivers for each of the main bandwidths, 3-way systems bring enhanced frequency definition to the listening experience.  

Each driver focused solely on its optimum frequency range.

A big picture!  

Enjoy the 3-way space and definition !
