Looking for matching sounding in-walls to a B&W LCR 6S2 center

Hi All, 
I own a B&W LCR 6S2 and would like to find matching sounding inwalls without breaking the bank.

Would the CWM664 match? If i have to,I would be willing to do 2 inwalls and a new Bookshelf type of center is needed to get all 3 to match 


Thanks in advance
