Audioholics and Sound + Vision love the new PB13-Ultra

"The PB13-Ultra was quite possibly the best subwoofer I've ever had in my system. It went lower and louder than any single-piece sub I've tried here, and it did so without producing a hint of excessive sound on the middle-bass octaves from 60Hz on up."

"Massive wattage and slick control in a compact package."

"The PB13-Ultra is a very powerful subwoofer that is competently engineered, heavily built, bulletproof, high tech and high output, possessing true extension to below 20Hz and a ton of configurability options. It’s a clear winner!"
