I liked my old Paradigm-10" sub, but what was I missing? All this talk about SVS, and anecdotes of happy customers. Did I really need to spend more money, or was I just suffering a flare-up of "upgradidess"? Last night, I found the answers to all my questions. After much internal wrangling over cylinder vs cube, and + vs ultra, I decided on the PB2 cube. Placed my order last Thurs., and was promptly greeted by the SVS team. The sub shipped on Fri., and was delivered before Noon on Monday. If you owned a company, this is how you would want it to be run. Impeccable packing and a menacing looking sub. After dragging it into my family room by myself (not recommended), I hooked it up and calibrated. (thank you steve nn , and others who helped me learn some new terms and understand what I was getting into). I was in Shock and awe (sorry to borrow the phrase, but I think it fit here better than in the war conflict). Between Dori tapping on the tank (Nemo), and Monsters, Inc., my whole couch/room/house was shaking with clean tight bass. I readily admit that I know very little of graphs, peaks, etc., but what I felt was a total immersion into the movie experience. And to those of you asking yourself - do I like bass ? - that is my subjective response as to why I am a newly confirmed bass-a-holic. To me, it's like the thrill of a roller coaster. That perfectly timed LFE puts you into the movie itself, if only for a minute. I can't wait to try out some music. Keep up the good work SVS.
