I A-B compare the MBL 121 vs MBL111B. No contest here - 111B wins big time. Without the sub they sound very similar. The Sub of 111B is similar to that of 101e and it's the size of a small fridge with 12" woofer goes down to 20Hz and with 30mm MDF and internally braced for extra strong construction. Even with large volume bass the sub didn't vibrate.
If you pair the 121 with another brand's sub make sure they blend well with it because not many sub out there are manufactured to the quality like MBL's. Personally I think the natural upgrade is to sell the 121 and get a 111 or 101.
