First Perlisten Audio THX Dominus in-walls now shipping

The world’s first THX Certified Dominus in-wall speakers are now available to UK home theatre designers. The Perlisten Audio models use the same technology found in the brand’s Hi-Fi speakers.

The flagship S7i LR, which stands nearly a metre tall but is just 101.6mm deep, is a 4-way system comprising four 7-inch woofers and Perlisten’s patent-pending Directivity Pattern Control (DPC) waveguided array of 28mm tweeter and twin 28mm midrange drivers.

By utilising passive beamforming, the proprietary waveguide is designed to achieve the precise vertical and horizontal dispersion of the beryllium tweeter, with an expanded bandwidth to 40kHz, and twin midrange transducers.

All three DPC drivers are housed within a dedicated rear absorption chamber to minimise internal reflections. The S7i LR’s fully sealed S-series cabinet is of aluminium and similarly damped with a bituminous layer to ensure a consistent frequency response with no enclosure resonances or sound leakage.

THX Certified Dominus requires more than double the output levels of the THX Certified Ultra specification, so the tweeter and dual midranges that comprise the DPC share the same high-power motor technology, with oversized Neodymium motors, shorting rings for low inductance, flux stabilization with low distortion, and Ferrofluid for power handling.

The S7i LR’s four 7-inch woofers handle dynamic transients.

Dominus is the newest and the largest performance class of THX certification, meant to bridge the gap between large home theatre speakers and those used in commercial movie theatres and exhibits.

Typical installations would be in rooms up to 184 cubic metres, with a 6metre viewing distance.

Karma-AV says the S7i-LR will be joined by S7i-C, S5i-LR, S5i-C, and S4i-LCRS surround models in Q4, allowing for a complete architectural THX Certified Dominus home theatre speaker 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 S Series in-wall designs,” says Dan Roemer, chief executive officer, Perlisten Audio. “It marks the first time a manufacturer has been able to achieve this specification in an in-wall model, created for the largest private theatres.”
