Last night I pulled the trigger on my PB13-Ultra for the first time. Oh My God that sub is awesome! As a previous owner of a Hsu Research VTF-3 HO Turbo, I thought I had experianced DEEP LOUD BASS. I was wrong. The VTF-3 HO Turbo is a bad *** sub, but lets get things straight, it ain't no Ultra!!!
The PB13-Ultra could be in a class of its own, I played Alanis Morissette's "Thank You" cranked up on the Emotiva both in volume and Bass Gain and Holy Crap! I thought it would bottom out, but the Ultra just kept going! and Going! Louder and Louder until family members started complaining
That Ultra is one powerful sub! Thank You SVS!
