Review ครับ:
"The PB12-Plus at least matches the performance of any subwoofer in this test, and its price is about 40% less than that of the next-least-expensive sub we tested. If you've got the space for this behemoth, it's probably the best deal going for a high-end subwoofer." Sound + Vision Magazine, 9/1/2009 by Brent Butterworth. Read Review.
"From its ungodly output capabilities, true 20Hz extension, and ability to play clean and distortion free, the PB12-Plus DSP has truly earned the right to be called a 'subwoofer'." 2010 Audioholics Product of the Year - Subwoofer Category Audioholics, 1/1/2011 by Paul Apollonio. Read Review.
"The SVS PB12-Plus is truly a chameleon among subwoofers. It can play loud; it can play soft and everywhere in between. It can play as well up high as it does down low, a quality many subs lack. Its multiple port tunings and parametric EQ mean it can work well in any room with any speaker system. Its build quality is on par with the most expensive products available and it looks great too. I'd have to say SVS has hit this one out of the park." Secrets of HT and HiFi, 2/1/2009 by Chris Eberle. Read Review.
