Introducing the PB13-ULTRA

PB13-Ultra - The Ultimate Expression in Sheer Power

Our flagship ported subwoofer the PB13-Ultra commands respect. At 155lbs it is physically imposing and monstrously powerful. Yet musical nuance and refined character are what truly earned its stripes. When sheer impact is what counts, the PB13-Ultra delivers its music and movie payload B52 bomber-style with strategic precision, subterranean extension, and jaw dropping slam and impact. When the score calls for sound in a supporting role, the PB13-Ultra is deft, and gentle—perfect in its part. This unmatched combination of power and poise will delight the discriminating audiophile and hard-core home theater enthusiast alike.
