Product Description

Perlisten R4i-LCRS


The R4i utilizes the same great technology of the R4b enabling a DPC array and timbre matching not only in the raw materials but in the critical frequency response, power response, and phase.  Able to blend seamlessly into any home theater as a stereo pair with a subwoofer, center, or surrounds to be the most useful model in the lineup for small, medium, or large home theaters.

It's all in
the details

Based largely on the R4s and R4b. Adapted for inwall applications. Shallow 4” mounting depth and integral aluminum extrusion rear enclosure insure consistent performance and minimal sound propagation to adjacent rooms. Sharing “trickle-down” technology from our flagship S-Series, the DPC-Array here based on three 26mm domes, guarantees excellent directivity control and timbre matching with all R-Series speakers. The Silk diaphragms developed ground up, chosen specifically their smooth, effortless representation of midrange and treble. The 165mm woofer is made from our proprietary HPF pulp, two years in development, bringing new technology to one of the oldest materials used in loudspeaker design. All R-Series speakers share the same DPC-Array and benefit from our unique timbre matching technique across the entire series. Another PERLISTEN inwall loudspeaker to be certified for THX Dominus – their highest rating.


The R4s/R4b designs adapted for THX Dominus Certified in-wall surround channel applications.
