San Francisco-based Perlisten Audio has teamed up with THX Ltd. to jointly announce the first THX Certified Dominus in-wall speaker, the S7i ($7,495, due to ship in November). Using the same tech found in the company’s S7t tower, the new S7i measures 39.25-inches long by 4-inches deep, and includes a 4-way self-enclosed aluminum cabinet with butuminous damping layer for consistent frequency response.

“THX is an important partner for our company. We were the first to introduce a THX Certified Dominus product, and I’m proud that our team can present yet another first with our new S7i,” says Dan Roemer, chief executive officer, Perlisten Audio. “It marks the first time a manufacturer is able to achieve this specification in an in-wall model, especially one designed for the largest private theaters of up to 6,500 cubic feet.”

THX Certified Dominus requires manufacturers to apply “more than double” the output levels compared to THX Certified Ultra specification. Perlisten says the high-power tweeter and dual midranges in the S7i all share the same motor technology with large Neodymium motors, shorting rings for low inductance, flux stabilization with low distortion and ‘Ferrofluid’ for power handling. The new speaker is also capable of smooth and clear dialog, and vertical and horizontal dispersion is accurately controlled with “beamforming” tweeters and midranges.

THX Dominus was designed bridge the gap between large home theater speakers and those used in commercial movie theaters and exhibits. Home theater owners with rooms of up to 184 cubic meters and a six-meter viewing distance (or up to 6500 cubic feet and up to 20 feet, respectively) can fill their listening rooms with THX’s signature reference and “superior” audio quality.
