Product Description

Perlisten S7i-C In-Wall Speaker

The award-winning flagship S7t design adapted for THX Dominus Certified in-wall centre-channel applications.

The next level in-wall with Directivity control to well below 1kHz while enabling a DPC array and timbre matching not only in the raw materials but in the critical frequency response, power response, and phase. In addition, the S7i is THX Dominus Center certified with the same amazing Sensitivity and THD as our famous S7c in-room center.  A true value in the largest sized home theater in-walls compared to almost any in-wall on the market and can be utilized as an Center with an acoustically transparent screen or as just a Center in the Media room.

It's all in
the details

Based largely on our flagship S7t. This is the center channel implementation. Here we have adapted the design for inwall applications. Shallow 4” mounting depth and integral aluminum extrusion rear enclosure insure consistent performance and minimal sound propagation to adjacent rooms. Featuring our proprietary DPC-Array controlling Mid/High frequencies, centered by our finest 28mm Beryllium dome and dual 28mm TPCD ultra-lightweight domes. All transducers are developed ground up by our engineers – bringing decades of research, culminating in this world class design. We teamed up with companies in the USA and Sweden to bring modern material science to hi-fi. Utilizing advanced Comsol acoustic modeling, our DPC-array is the result of 18 months of painstaking simulations and prototyping. The result is one of the most technologically advanced loudspeakers available. This new tweeter/waveguide DPC-Array delivers amazing accuracy, smoothness, and directivity control to handle the critical vocal range and delicate treble. All S-Series speakers share the same DPC-Array and benefit from our unique timbre matching technique across the entire series. The PERLISTEN S7i is the world’s first and only in-wall loudspeaker to be certified for THX Dominus – their highest rating. A mark of achievement.
