BG Radia's BGX-4850 in-wall subwoofer shakes loose a rave review
It's been a while since we heard about BG Radia's THX Ultra2-certified in-wall subwoofers, the BGX-4850, so we were pretty happy to see that AVGuide put them to a review. Word to the wise -- don't scoff at the small 4-inch drivers used in this subwoofer; by packing 48 of those little cones into each module in a kind of boxer style layout (Porsche and Subaru fans take note), the BGX-4850 (combined with a 2,200-Watt amp and a healthy dollop of DSP) turned loose sub-20Hz response that the reviewer ate up. No smudgy, slow, plodding bass here -- quite the opposite, actually. The reviewer said the transient response may outpace some of the primary speakers with which it's paired; something good is going on here. Good enough, in fact, to net perfect 10s for everything but the "value" portion of the competition; somehow you just knew that $7,000 tag would catch a snag somewhere along the way.
BG Radia's BGX-4850 in-wall subwoofer produces THX Ultra2-certified shock and awe
The ribbon drivers BG Radia uses across its speaker lineup safely puts the company in "high end" territory, but getting big bass out of ribbons is seriously challenging. The company has used conventional drivers in a THX Balanced Bass-line arrangement to solve this problem with its BGX-4850 in-wall subwoofer. The speaker uses balanced pairs of modules, each with 12 micro-woofers, to generate a thumping surface area equivalent to two 18-inch drivers. Add in a healthy 2,000-Watts of oomph, and you've got vibration-free bass coming out of your walls at "lifelike playback" levels, courtesy the first in-wall sub to earn THX Ultra2 certification. Everybody will know where that $7,000 went, so warn the neighbors.
