DESCRIPTION
WOOFERS
Using the same principles applied to Midranges, we developed with SEAS two 180mm ultra-linear recessed drivers.
The driver is powered by our unique curved cone in ultra-hardened woven polypropylene to achieve great internal damping and
perfect control over the moving parts, that are always perfectly matched to deliver a fantastic frequency response.
To allow extreme coil excursion with low distortion, the magnet system features a bumped back plate with long and light weight
copper clad aluminium voice coils. The heavy copper ring below the T-shaped pole piece reduces non-linear and modulation
distortion.
Bullet shaped phase plugs reduce compression due to temperature variations in the voice coils, preventing any resonance problem
that could occur and also increasing the long-term power handling capacity.
The basket obtained with MIM and the basket's spider design are developed to preserve structural alignment for maximum stiffness
and also to reduce unwanted noises from air flows, resonance and sound reflection.
CROSSOVER
For XT-7 we developed a deluxe crossover with state-of-the-art components all exclusively provided by Mundorf and Clarity: the
passive Crossover Low-High Dual-Slope cuts at 280Hz & 3000Hz and features a resistive design to enable ultra-linear load that
support the work of the amplifiers minimising the stress on power supplies even at a nominal impedance of 4Ω.
The boards are made of thick audio-grade and anti-resonance glass fibre with 4 oz gold plated conductors and power a
sophisticated triple crossover network and a summing midrange multi-slope design perfectly integrate the drivers of the array for a
fulfilling close field audio experience. This high quality crossover is completed with Mundorf handmade air winding coils and Clarity
& Mundorf caps.
