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.
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.

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.
