Insane.......... that is the word for this SVS PB16-Ultra. ABSOLUTELY INSANE!!!! Picked up one today, the amount of bass that comes out of that beast is ridiculous. Not only that, it is mammoth in size. You could literally put this at the end of the couch for a table. The sheer size of it alone is just jaw dropping, the gloss finish is beautiful. The bluetooth app is perfect, all kinds of adjustments. This is by far the largest sub I have ever owned. 175lbs. On the screen is Batman VS Superman, when he fires the gun, I can literally feel it in my chest and the couch, not to mention all the other low frequency stuff happening at the time courtesy of Hans Zimmer. Music just floats on by with "I'm here!" bassline. There is a little bit of sheer terror in thinking about turning it up, I think it might crack my walls. I am literally insane enough to buy a 2nd one and place it diagonally in the other corner, I already told the owner of the store where I got it that I'll be back for #2.
