I'm still a bit stuck on what to do (big surprise) lol

I'm still debating whether to get two tower speakers and be done with it, or to get two bookshelves with stands and a separate sub. I'd personally prefer to avoid the sub for power consumption savings and the piece of mind that my roomates would forget to turn it off and leave it on all hours of the night.
I see reviews of subs on the Aperion website and see people saying they could get the 8" $500 one to shake the windows, which is absolutely not my goal at all. I don't want or need that power or response ast all (I live in a townhouse), just want a little bass punch which I'm still convinced good towers could give me (havn't listened to them though).
I still don't have a receiver, but want that new Pioneer that will be released next month. And when it comes out, I'm still going to wait a few weeks to see if any problems or issues come up with that model from owners on this board (I do a lot of research). Otherwise I'd jump on the 5Ts and try them, and if I still feel they don't give good bass for my purpose, I'd exchange them for the 6Ts. And if I still wasnt happy, then I'd try the 5Bs and get a sub, and still not happy, then exchange again for the 6Bs and sub. I would use the exchange feature of your products within the 30 day period (if I can do that). Personally I feel I'd be happy after the second exchange, but that's some $$$.
Guess I'll just keep reading reviews and wait for a "professional" review or two until that Pioneer receiver comes out.
I also probably mentioned this previously, but I will be listening at low-medium volumes, and don't want to be listening to a speaker that's not sounding it's "potential" because it's not being driven hard enough.
