So after about 5 years of "thinking" about it - I found a deal I couldn't pass up on a Yorkville XC808 cab. Has some scuffs - but overall really good shape. Have it paired up with my Monoblock. Sounds good. Until now I have been using an old Doyle 15" cab with a JBL 140 in it. It too sounds great - but the cabs are a different great. The whole house vibrates when I use the Mono w/ the 808. I'm happy.
