Based on the S4s and S4b speakers, the S4i has been designed to work as LCR or Surround in in-wall applications. Shallow 4" mounting depth and integral aluminum extrusion rear enclosure ensure consistent performance and minimal sound propagation to adjacent rooms.
Featuring Perlisten's proprietary DPC-Array controlling Mid/High frequencies, centered by the finest 28mm Beryllium dome and dual 28mm TPCD ultra-lightweight domes. All transducers are developed ground up by Perlisten engineers - bringing decades of research, culminating in this world-class design.
Perlisten teamed up with companies in the USA and Sweden to bring modern material science to hi-fi. Utilizing advanced Comsol acoustic modeling, the DPC-Array is the result of 18 months of painstaking simulations and prototyping - one of the most technologically advanced loudspeakers available.
All S-Series speakers share the same DPC-Array and benefit from Perlisten's unique timbre matching technique across the entire series. Another Perlisten in-wall loudspeaker certified for THX Dominus.
