I'm writing to see what people's opinions are of the the PSB 4T and Subsonic 5 vs PSB 7PT. I can get both of them for approximately the same price. I've heard the 4Ts and liked them, but thought they were a little weak on the bass responce. I could add the Sub 5, but I am concerned about neighbors below complaining as I live in a condo. I have yet to audition the 7PT, as its been difficult to find someone local with it. I believe it has an adjustable bass control on the back, but if someone has a more detailed explanation on how it works I would appreciate it. Oh, my listening room is rather small, but will be expanding in 2 years, so I'm looking at this in more of a longer term than near term decision (ie i could also add a sub to the 7PT when the room warrants it). Any opnions would be appreciated. Oh, I'll be running a NAD 752 in front of it.
