George, great choice.
I have the S-8's for fronts and S-4's for my rears; we love them!
I suppose one could always find a "better" speaker out there.
IMHO, how much better is better, and where does the search end, if ever?
I got the S-8's and never looked back. It's what sounds good to you.
As far as bass is concerned, I only use the sub (seismic 12) for movies.
You shouldn't have to pay list price, so don't.
Also, if you don't mind a less than perfect finish. blems may be available, at an even greater savings.
