I have used MBL 101 E speakers the last five years, and love them !
They are power hungry, hard to set up and ruthless at finding the flaws in your system. But when everything is right they just bring you to the recording venue. Good live recordings are just spooky with these speakers. I have used them in relative small rooms with success, you need a little over 1 meter of room behind them and a lot of absorbers on the side walls. They do work best with the big 9011 MBL amps, the mid bass is hard to energize with lesser amps.
I used big Krell FPB 750 amps and did not realize how much better the mid bass could get, until i got a 9011 in the system. There is a synergy between these amps and the power hungry speakers. I currently use only one amp set up for stereo. My listening levels rarely exceed 85 dB, and can not recommend levels under 75dB.
