Diffs. between $1400 ACI Maestro C & $1999 XL?

ACI is running some good specials right now, but I'm wondering, outside of being forward firing, if there are any other differences between that $1400 Maestro C and the downfiring $1999 Maestro XL?
It's my understanding that the sonics are the same, it's the finish that's the only difference. Go to audioc.com or audiocircle.com and look for the ACI Forum if you want more info.
