Perlisten S7t Limited Edition

Innovative Evolution

Now, just 2 years removed from the launch of the S7t and all the derivative S-Series models, the engineering team of PERLISTEN™ has taken another step forward in sonic performance

We’ve revisited all of what makes the S7 great, applied what we have learned, and have pushed the state of the art just that much ­further ­forward. We have updated the ­woofers to ­increase linear excursion, lowered inductance and increased low frequency capability. The DPC-Array, while maintaining the existing drive units and pattern control, we’ve coupled all 3 transducers to a massive aluminum heatsink that takes power handling and reduced thermal compression to all new levels. Even the crossover has been ­up­dated. Now all of the components are hand sorted to 1% tolerances. Final part values and pair matching to 0.5dB will be performed at our USA head­quarters by our CEO, Dan Roemer. Each speaker will be ­measured ­using our Klippel nearfield scanner. The measurement data of each unit will be provided to the proud owner. The final step will be signing, ­certifying, and serializing each speaker. Truly a work of art like none other.

Textreme

THIN PLY CARBON DIAPHRAGM

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

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.

IsoAcoustics isolation

With the added performance of the ­refined woofer design, the need for ­better stability and vibration isolation is now more important than ever

Working with the Engineers at IsoAcoustics, leveraged from their patented technology, we have developed a custom PERLISTEN™ isolation/damping system only available on the S7t-Limited. This provides a high degree of isolation while resisting lateral movement and oscillations to maintain alignment with the listening position. Internal reflections from the hard-supporting surface are attenuated resulting in greater sound clarity and openness. Furthermore, the massive 18 kg machined steel base keeps the speaker cabinet grounded.

Updated ­Cabinet with Carbon Fiber

The cabinet structure of the original S7t has been upgraded with radiused carbon fiber over HDF side panels

Initially intended for its stunning beauty and increased stiffness, the radiused panels also create a moderate 8% increase in cabinet volume without increasing the speaker’s footprint. The increased volume allows for full advantage to be taken of newly designed woofer’s excursion capabilities.

Re-designed Crossover

Our most ambitious endeavor yet

In order to take the S7t-Limited to new heights of performance we’ve not only revised the crossover ­design for the new cabinet and woofer, but for the Limited Edition we now are ­sorting all components to 1% tolerances. Furthermore, for the limited edition, each speaker pair and crossover are hand matched to within 0.5dB at our USA Research and Development headquarters ­located in Madison, WI. Here at our headquarters, we will perform ­Klippel nearfield scans of each speaker, pair match, certify and provide each customer with spinorama measurements of their actual speakers.

engineered & perceptualized in USA

Each pair of speakers will be hand matched and certified at our ­headquarters located in Madison, ­Wisconsin

Here we have the ability to perform a full battery of measurements. And for a very limited and exclusive run of S7t’s, we will provide these measurements to the owner certifying the results. Each speaker will be individually signed and serialized by our CEO, Dan Roemer.
