Welcome
Welcome to the site. And I mean that. That being said, I don't know how much you looked around here, but like most Audiophile sites, Bose are not the most respected brand on the market, to say the least. My suggestion would be, if you still have the receipt, return them and do some research into some other brands. You could pick up four Athena bookshelves (B1s or B2s) and have a better set and pocket some cash on top of it. Check out some of the online vendors as well. Axiom would be a good start.
I once bought a pair of 301's myself a long time ago. I used standard mounts and they worked well. Then the WAF kicked in, this time it was a blessing. She hated them, so I returned them and bought a pair of Mirage FRX-ones (now discontinued). The were about half the size and sounded 10 times better.
I hope this helps and is taken in the spirit thats intended.
