I own those satellites as I live in an apartment, and I think they sound great for teh money. Receiver wise, at that price point, it will be a lot of variations of the same. I like the pioneer better, but that is totally based on the setup process (I am a ht installer)
IMO $200 is WAY too much for a used sub-10. Hell, I have a spare one of those I gave away.
They're not bad subs, but since you can go to best buy and purchase a brand new bic 10 for under $150 shipped... Its just too much.
