NEW SUBWOOFER DRIVER
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.
Z38
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.
ROTATABLE WAVEGUIDE
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°
OR
70° x 100° – the Horizontal and Vertical dispersion can easily be changed.
3-WAY DESIGN
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 !
