Your better off looking in audiogon or craigslist for some used speakers. Those HTIB speakers won't give descent stereo sound. Onkyo has good receivers, but someone else built their speakers.
Retail, $500 it isn't a bad deal...but look around for someone getting rid of their old ones because their wife made them buy Bose!
Then find the receiver that matches their impedence and your needs.

Good Luck!
