MBL 111F or 101E ????

Hi experts :)

I am looking to get a new system and I want to hear your input.

I am currently have a Devialet Expert 1000 Pro, my room is 4 meters wide, 9 meters in length because joining with dinning area and an open kitchen next to the dinning area, so it’s like a L shape opened space. I haven’t done any acoustic treatment to it yet.

i have a long tv bench, so the speaker going be about less than half meter away from side walls and may be about half meter away from back walls, this is the limitation I can’t change and will never change unless I move house.

i wondering according to my room space and current equipment, should I get a MBL 111F or 101E???? If 101E will performs better, how much better? Distinctly??? The 101E is quite a bit more expensive than 111F.

I can change my current amp to the MBL N51 integrated amp but that’s it. I cannot afford their 9008 amps and pre-amp combinations, and probably not in any soon future. I am not sure if the single N51(350wpc) will perform better than the Devialet 1000 Pro(1000wpc).

Can any MBL Expert give me some input?

Thanks a lot!!!

Thanks for your info.

I heard many amp have problem driving speakers lower than 4ohm, the MBL looks like never fall below 4ohm, I hope it will be fine otherwise I need to trade in for the MBL N51 integrated amp.

have you listened to both 111f and 101e mk2? Any thoughts?

I'm sorry, but feel I have to raise it again--does anyone here who has heard the mbls (and I have heard them sound wonderful placed out in a room) think that they will work essentially placed in the corners of a room as the OP states (1/2 meter from both side and rear walls)?  I fear that the OP will be sorely disappointed with their performance in such a position, no matter what amplification he chooses, and that's a lot of money he's thinking of putting into those speakers.  Do you think the smaller 121s would work, Prof?

Honestly, I would not want to place MBLs, incuding my 121s, that close to the side/rear walls.  I wouldn't place any speaker (with few exceptions)
that way. 

My 121s are well out into my room - I tend to like almost nearfield listening. But I also had them further away, probably about 3 feet from the back wall, and they sounded excellent then too.  I just prefer less room sound no matter what speaker I'm using.

Pepa, you need to look at the whole picture, ohms and -phase angle combined, which is call EPDR (equivalent peak dissipation resistance).

 EG: a Wilson Alexia, is specified as a 4ohm speaker, but it has a dip at 60hz-80hz of 3.6ohms and a negative phase angle of -43 degrees, this presents to the amplifier a load of .9ohm!!!!! (Yes that's point nine of an ohm.)
This is enough to ruin any amps bass performance save for the very best that can deliver both big current and watts.

My friend (reviewer) has these Alexia speakers, and they sounded great with the Parasound Halo JC1 Monoblocks (designed by John Curl) we thought it doesn't get better that this, massive current and watts with high bias Class-A switch.
Then he reviewed the massive Gryphon Antillion Evo's and he owns it now instead. 

Cheers George

Thanks for joining the discussion.

i have a friend he owns a 101E MK2 and placed at the corner like my situation, but it sounds amazing, it possibly will do better in a better position but the current result isn’t bad at all.

If anyone has experience with the 101E and 111F can you please share your thoughts about the difference between them?
