First, i want an SVS, but I just can not afford one right now. I have a Sony WM40 now with the Onkyo SKS-HT500 speaker system. The room is 11'3" by 33', part of it is the dining room. I can get 102 to 105 peak DB's at the sweet spot, but I'm pushing the Sony kind of hard. I'm running it 7 to 9 DB's hot. If I turn off the SUB I can get the Onkyo's to go louder and still sound good. I don't remember what the DB level was with out the sub. If I add another Sony that will give me 6 more DB. What I'm thinking is, I can run the subs around 7 to 9 DB hot for the pair so I will have more bass. Will this give me more seat of the pants feel? Or should I just buy one Audiosource SW-15 and sell the Sony? Would this give me more bass (feel) and total system volume? I also want to get JBL S-26's or S-38's and an S Center some time in the future. What would you do first? 1) Save for an SVS (it will be a while) 2) Buy another Sony 3) Buy an Audiosource SW-15 4) or buy the JBL's (it will be a while) S-26 all the way around S-38 front and S-26 rear S-38 all the way around I know this is a lot of questions to ask and I hope I made them understandable. Thanks for your time.
