I purchased an SVS 20-39 PC Plus. I just took the risk... and just let me say... I could not be happier. Ron answered all of my questions... the shipping was TOP notch and the thing looks great. My wife and I watched Cat Woman tonight.... she was actually giving me "The Look" during the flush scene. Why? Because the SVS was shaking the whole damn room... violently. It was very cool. I have yet to bottom it out. I paid about $850. I originally though I would need two for my room... but the placement I have in the corner worked perfectly. One works more the adequate!!!

Don't even concern yourself... you will be very happy. Now you just have to decide between a cylinder or box. Good luck!
