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.
