None of the Axiom bookshelf speakers are more than 11" deep. I own some M22s and they are excellent. By most reports, the Axiom center channels are very good also. You can't go wrong with an Axiom bookshelf/center combo. And you can only spend $825 with the most expensive options. With that being said, it might be worth getting a listen to the Polk LSi7s if you would be willing to spend a little more. The CSi center channels from Polk are outstanding (I have a CSi5 my sister has a CSi3 and we are both very pleased) and the LSi bookshelf series has received rave reviews but the LSi7/CSi3 combo will cost over $1000 if you pay retail. Some other folks will probably chime in with some other good options (Rocket?, Ascend among others) - although it is an Axiom board so that will be the overwhelming preference expressed here - and it is a great option.
