I'am looking at upgrading my system in the next month or so. The room is 18x11x8 with a large window on the 18' wall. I have an Onkyo 818 that I will be running my system and would like to keep it at 5.1 at this point. My usage will be about 75 HT 25 music The speakers I am leaning towards are paradigm studio 60 for the mains, 20 or 10's for the rears, 590 center, and the sub hasnt been chosen as of yet. The sales guy was telling me about definitive tec for a sub, but from what I have been reading I am considering SVS 13 Ultra. I have a Polk PSW 125 in my current system that I was considering using with the new system if the budget doesn't allow for a new sub right away. How do you think this will work with the new speakers. Any other ideas with speakers in this price range. I like the idea of buying Canadian made products and thats what steered me away from PSB as they have gone totally off shore. Thanks for all of your suggestions|!
