The first Gold Note loudspeaker to feature a ribbon tweeter, this AMT ultra-linear unit is enhanced with a metal dampened rear chamber. With a new custom cooling coil radiator and dampening aluminium blocking bar designed for resonance reduction and to increase extension linearity.
A 160mm ultra-linear recessed driver developed with SEAS and enhanced with a proprietary metal chassis.
The unique curved cone in ultra-hardened woven polypropylene allows an excellent internal damping factor while the moving parts are perfectly matched together for a smooth and extended frequency response.
A special radial reinforced low loss rubber surround reduces radial resonances and prevents surround break up at large excursions.
The custom aluminium phase plug reduces compression due to temperature variations in the voice coil, avoiding the resonance that would occur between the dust cap and the pole piece while also increasing the long-term power handling capacity. The internal ring around the coil drastically reduces distortion and inter-modulation.
The basket, obtained by MIM (metal injection molding) to achieve extreme stiffness and stability, keeps all the components in perfect alignment.
Large windows above and below the basket's spider are designed to reduce sound reflection, air flow noise and cavity resonance to the minimum; the custom spider enhances driver's excursion and give better details and greater linearity.
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.
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.
