I have the S60's and that would be my recommendation. I paid $698 for the pair at visions 6 months ago. I also have a pair of HTS12s. Very capable sub for the $348 each I paid, also at visions (lowest price of the year was $299 at Best Buy a few months ago). Ask the visions sales rep if he can match these prices. He may not be able to right now (based on his costs) but he may be able to offer an additional discount.
You can also go with the S20's for your fronts. Also very capable and with the HTS12's you wont be lacking anything.
