Perlisten Audio Debuts First THX Certified Dominus In-wall Speaker

Perlisten Audio now boasts what is says is the world’s first in-wall speaker, the S7i (SRP: $7,495 each), to achieve THX Certified Dominus status.

THX Certified Dominus demands more than double the output levels compared to the well-known THX Certified Ultra specification.

The new speaker, scheduled to ship November 2021, utilizes the same advanced technologies as the company’s S7t tower speaker.

Fully Self-Enclosed Cabinet

The new S7i, which measures 39.25 inches in length and has a depth of only 4 inches, is a 4-way fully self-enclosed aluminum cabinet in-wall with a bituminous damping layer to ensure the frequency response is consistent in any installation.

“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,” said Dan Roemer, CEO, 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.”

To achieve THX Certified Dominus status, the high-power tweeter and dual midranges in the S7i all share the same motor technology. They utilize massive Neodymium motors, shorting rings for low inductance, and flux stabilization with low distortion, a damped anti-resonant back chamber to remove internal reflections, and Ferrofluid for power handling.

The four 7-inch woofers recreate the dynamic range needed for huge transients while remaining under control.

Beamforming Tweeter and Midranges

Perlisten’s patent-pending Directivity Pattern Control (DPC) waveguide is centered by three 28mm “beamforming” tweeter and midranges to accurately control vertical and horizontal dispersion. A beryllium tweeter with expanded bandwidth to 40kHz and a rear absorption chamber reduce internal reflections to the bare minimum. The Signature S7i effortlessly recreates the high output levels required for THX Dominus, with vocals that are silky smooth and dialog that is consistently clear.

Dominus is the newest and the largest performance class of THX certification, meant to bridge the gap between large home theater speakers and those used in commercial movie theaters and exhibits. Home theater owners with rooms up to 184 cubic meters of space and up to a 6-meter viewing distance (or up to 6500 cubic feet and up to 20 feet, respectively) can fill their listening rooms with the superior audio quality they expect from THX Certified products.

“Perlisten Audio is committed to the custom integration channel,” Roemer added. “You’ll soon see several additional in-wall models in the coming months each of which are created to give installation professionals high performance with demonstrably improved in-wall speakers for their largest projects.”
