Well I received my SVS 20-39PC+ today after thinking it may not come till Monday, which really would have depressed me. Anyhow I just did a little fine-tuning "test tunes from receiver" and set it up at 75db and right now it’s about at 80db on the sub. I have it really hot right now just experimenting with room size and how loud I can play it. A lot of you probably think that this is way to hot but i can never play anywhere near reference level in my apartment. The upstairs lady complained about my PSW650 which from what I am finding out now cant come anywhere near the vicinity of this SVS Monster SUB!!! The first test i did was with MONSTERS INC. I remember a lot of people saying how loud the part was when they had to bolt down that sock in the beginning of the movie. Well my PSW650 really didn’t do anything for me with that scene. So i fast forward to that scene and was expecting a little more bass then i heard previous. TO my surprised it literally scared the crap out of me, it even knocked one of my girlfriends candles off the top of the TV. I’m going to be testing a lot of movies in the next couple days and I am going to buy The Haunting DTS and Saving Private Ryan as well. I want to see what all this hype is about with the HAUNTING. Well I'll keep people updated but as for now I think I am going to try calibrating with the AVIA disk and see how that turns out. Also I can say that everyone is right about their customer service, I received a free T-Shirt from them since my sub shipped a little later then normal. Keep up the great work you guys at SVS, I work at Circuit City and everyone cant wait to come over and hear what this thing can do. You will probably get a few more customers from them and from me telling customers at my store that are looking for very high end Subwoofers about SVS.
