Each part is precisely cut to 0.1mm tolerances, heat treated and then ultimately anodized to the final cosmetic. The real benefit is not just cosmetic and mechanical. Here, the aluminum DPC doubles as a massive thermal heatsink for all three dome tweeters in the array conjoining the existing aluminum heatsinks that each tweeter assembly already employs. Unique to the S7t Limited, they are now thermally coupled to the aluminum DPC. This not only increases power handling and reduces thermal compression of the individual units, but also maintains the same temperature across all drive units. This ensures the complete DPC array tracks as a single unit, effectively avoiding thermal runaway of any one tweeter or any non-linear compression from one unit to the next. This technique is often applied in audio amplifier design, this is a first for multiple loudspeaker transducers.

Updated Cabinet with Aluminum Side Panels

The original S7t's cabinet structure has been significantly enhanced with the addition of aluminum side panels.

These panels not only add mass to the S7t Black Edition but also bring a host of benefits, including improved damping and a sleek, modern aesthetic.

The S7t Black Edition, with its robust aluminum construction and stunning architectural design, is a testament to the perfect marriage of art and acoustics. This unique combination not only enhances the speaker’s volume and clean look but also delivers more woofer excursion and Perlisten’s top performance to date. 

CNC Milled DPC

At the heart of Perlisten premium speakers is our USA-patented DPC array

The (TPCD) TexTreme carbon fiber used in our midrange drive units is also the key to the performance of our woofers, resulting in lighter-than-air dynamics and the impact you expect in a flagship Speaker that can play down to 20Hz in-room.

This technology is 30% lighter than standard carbon fiber of the same thickness, with increased strength from using the unique process of stacking multiple layers. The unique weave is unmistakable and distri­butes break-up modes without sharp response peaks, while extending bandwidth. Simply perfect.

Improved Woofer featuring Extreme

The S7t already set the standard for PERLISTEN™ bass performance

With accurate transient response, low distortion, and excellent low frequency extension. Is it possible to improve upon this? Drawing on the existing Textreme thin ply carbon diaphragm (TPCD) and suspension components, we set out to improve low frequency capability and thermal management. The re-designed voice coil and magnetic circuit now enable 20% more linear excursion, yet further reduced the overall inductance. This was achieved by utilizing a secondary shorting ring and re-designed voice coil windings. The secondary shorting ring doubles as a large heatsink inside the motor structure, coupled to the external copper heatsink using a unique mounting system of aluminum fasteners. The external heatsink is floated above the rear of the t-yoke assembly allowing for convection cooling of the voice coil and heatsinks as the air flow created by the voice coil’s excursion quietly flows past. All of these refinements yield improvements in all key performance categories: Linear excursion, distortion, thermal compression, transient performance, and midrange clarity.
