Duet 7 Reference
A tower with limitless detail and transparency in a 3 way package that adds power handling and command of the music. Available by special order only.

We are using the amazing sounding 7" Scan Speak Illuminator aluminum cone woofers.  These woofers have about twice the xmax compared to most 6.5" drivers, and they have class leading low harmonic distortion.  The choice was obvious.  To match the speed and detail of the bass, we selected the Accuton C158-8 midrange driver.   This midrange is highly transparent because it has the latest generation finite element designed Accuton motor.  It's cone surface area is like a 6.5" driver-- thanks to the unique basket.  The transition to the 1" Accuton inverted Cell dome tweeter with undehung voice coil is seamless, and here we are using only the best parts in the signal path. The crossovers are hand wired using Supra's top tier wiring.  Best of all, this speaker has gone through many refinements, and we built it so that each design consideration was utilized to its fullest potential.  This is evident from the hand crafted curved front baffle edges for low diffraction, the point to point soldered crossovers, to the carefully selected and matched transducers.
