The global audio brand KEF has announced that its Marlboro, N.J.-based Demonstration Cinema has obtained THX certification.

Located in the KEF Music Lounge, the Demonstration Cinema incorporates a number of the company’s THX Certified Ultra loudspeakers and subwoofers. KEF emphasizes that in order for the entire space to receive THX certification the speakers, along with the whole listening space and viewing environment were tested and verified in order to achieve the THX status.

The experience of listening to a movie in the 9.10.6 KEF Cinema is absolutely transformative. The room vanishes and you are transported into the cinematic soundtrack,” states David Kroll, vice president, KEF America.

“The Atmos height control is so precise, you can hear that the orchestra is positioned below the floor in their pit. Even when listening at THX reference levels the system is so well balanced tonally you could relax all day, enjoying movie after movie.”

Digging into the specifics of the Music Lounge Demonstration Cinema, KEF explains the the system must produce crisp, clean audio to support the emotional depth and texture of movies and video. KEF says that in order for a speaker to gain THX certification it must pass hundreds of lab tests.

KEF’s Demonstration Cinema occupies more than 9,500-cubic feet and it includes a Seymour Screen Excellence 160-inch 16:9 projection screen that is located 18-feet from an Epson projector.

The system also includes products from Acoustic Innovations, Indy Audio Labs/Acurus, Straight Wire and Parsound.

Elaborating on its speakers’ THX Ultra Certification, KEF says these speakers are designed to meet specific design and performance criteria for larger rooms—3,000 cubic feet—with a target listening distance of 12 feet.

Examining the room itself, KEF stresses the acoustical design of the Music Lounge meets THX criteria for reverberation time, background noise, sound pressure levels (SPLs), frequency response, delay times and speaker placement.

“We are pleased to announce THX Certification of KEF’s high-end Music Lounge Theater, along with reinforcing the THX Certified Ultra seal achieved by KEF for the line-up of included speakers,” comments Peter Vasay, the head of the THX Certification program. 

“The launch of this elite listening lounge demonstrates KEF’s continued commitment to providing its customers with an elite entertainment experience, and THX remains a proud KEF partner to ensure their products meet our rigorous, high standard of audio quality.”

The KEF Music Lounge is by appointment only through authorized KEF professional integrators. KEF also emphasizes the facility follows New Jersey Covid-19 protocols.
