BGX 4850 Subwoofer

The BGX-4850 is the first in-wall subwoofer to achieve THX Ultra2™ certification as well as 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 BGX-4850 subwoofer is as dramatic in appearance as it is advanced in technology and performance. Incorporating proprietary THX technology, the BGX-4850 promises to deliver incredible bass performance with minimal distortion — even in large home theater venues.

“From the very onset of our partnership with BG, we wanted to create an in-wall subwoofer that delivered THX Ultra2 performance in a design that is appealing to the eye and ear,” said Laurie Fincham, Chief Scientist and vice president of R&D at THX. “The THX Balanced Bass-line technology, with its speaker drivers totally self-contained within their own enclosures, allows the BGX-4850 to produce deep, natural sounding bass without shaking the walls.”

The BGX-4850 consists of four separate in-wall bass modules driven by the BGA-2104 rack-mountable power amplifier/DSP equalizer controller. The bass module contains twelve micro-precision woofers, each sealed in an airtight enclosure, and arranged in six balanced pairs. The four modules have a total radiating area equal to two 18 inch drivers, yet fit completely inside a standard 2x4-inch stud-wall. All that is visible to the listener is a tall, slim grill 26.5 inches high and just 7 inches wide (per module). Because the subwoofer modules are entirely self-contained, they do not rely on the wall cavity or a separate back-box, to deliver resonance-free, natural bass. The BGX-4850 can also be adapted for on-wall or in-room use.

“The tall, slim profile of the BGX-4850 subwoofer is unobtrusive and blends harmoniously into any décor. It just disappears into the wall, yet delivers incredibly powerful, lifelike bass with virtually no distortion,” said Warren Kocmond, Chief Executive Officer of BG Radia. “By integrating THX Ultra2 performance into a revolutionary subwoofer design, BG and THX partnered to provide custom specialists with a compelling speaker solution for both high performance Home Theater and critical music listening.”

Powered by more than 2,000 watts of power, the BGX-4850 THX Ultra2 Certified 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 a single 2u high, 19-inch rack mountable controller/amplifier unit. An LED display and remote control are included.

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.
