BG Corp. Introduces First THX Ultra2 Certified In-Wall Subwoofer

World’s First In-Wall with Ultra2 Certification and New THX Balanced Bass-line — Delivers Powerful, Vibration-Free Performance

CES ’07, Las Vegas, Jan. 8, 2007 — BG Corporation, the world leader in large powerful in-wall loudspeakers, and THX Ltd., the leading provider of technologies, certification programs and quality assurance standards for the entertainment industry, today introduced the BG BX-4850, an in-wall subwoofer that incorporates design concepts and technology developed by THX into a unique design suitable for today’s homes.

The BG BX-4850 is the first in-wall subwoofer to achieve THX Ultra2 Certification, and the first audio product to incorporate THX Balanced Bass-line, a proprietary new THX technology for delivering vibration-free bass from a very compact speaker design.

The new BX-4850 Ultra2 In-Wall Subwoofer will be shown in private demonstrations in the Renaissance Hotel at the 2007 International Consumer Electronics Show, beginning here today.

The BX-4850 Ultra2 In-Wall Subwoofer is as dramatic in appearance as it is advanced in technology and performance. Incorporating advanced THX technology, the BG Ultra2 promises to deliver incredible bass performance with minimal distortion.

“The technical challenge was to achieve THX Ultra2 performance from a compact, in-wall subwoofer in a design that is aesthetically pleasing,” said Laurie Fincham, Chief Scientist at THX. “The slim, yet elegant design minimizes the often hollow, unnatural bass sound caused by wall vibrations, ensuring that homeowners don’t experience distracting vibrations during their favorite movies and musical presentations.”

The BX-4850 THX Certified Ultra2 Subwoofer consists of four modules, each containing 12 micro-precision woofers mounted in their own enclosures and arranged in balanced pairs. The 48 woofers have a total radiating area equal to a two 18 inch drivers, yet fit completely inside a standard 2×4-inch stud-wall. All that is visible to the listener is a tall, slim grill 26 inches high and just 4 inches wide (per module). The subwoofer modules are entirely self-contained, and do not rely on the wall cavity in which they reside, or a separate back-box, to deliver resonance-free, natural bass.

“The tall, slim profile of the BX-4850 Ultra2 Subwoofer is unobtrusive and blends harmoniously into any decor. It just disappears into the wall, yet delivers incredibly powerful clear sound with virtually no distortion,” said Paul Kahn, Chief Executive Officer of BG Corp. “By integrating THX Ultra2 performance into a revolutionary in-wall subwoofer design, BG and THX partnered to provide CE pros with a much sought after speaker solution for their high-end Home Theater and music situations.”

Powered by a total of 2,400 watts of power, the BX-4850 THX Certified Ultra2 Subwoofer is capable of producing lifelike playback levels with even the most demanding entertainment content. The amplification, digital signal processing (DSP) and control are all contained within two 1.5u high, 19-inch rack mountable controller/amplifier units.

Considered the benchmark for Home Theater products, THX Ultra2 Certification is designed for home audio enthusiasts who demand peak performance. It offers uncompromised playback of multi-channel movies, music and games, and incorporates new features and power requirements for premium Home Theater receivers, pre-amplifiers, power amplifiers and speakers that can distribute an optimal soundstage across wide viewing areas in dedicated Home Theaters.

The new BG BX-4850 Ultra2 Subwoofer is expected to be available through authorized BG Corp. dealers in the spring.
