I replied right after I posted above, but for some reason it didn't show up. He has no left side wall if he does not relocate the speakers. If he does, he will have no front wall behind the speakers.
I defer to your experience Mike - "your room is fine for MBL 101e Mk2's" - but I am surprised that he does not need both side walls a few feet away from the MBLs, and a front wall a few feet behind them.
Guess it shows that old dogs like me can still learn new tricks... :huh:
I’m really starting to figure out the MBL’s. It’s taken many many hours, but I’m really starting to figure them out.
Good question. I have asked Jeremy from MBL repeatedly and he insists you don't need side walls, that they will work fine. I'm about to find out as I have a pair of 120's coming (and there's a hallway on one side and no sidewall on the other in that room. They also work better with natural diffusion like plants and less absorption. They also work amazingly well in the near field (CLOSE to an equilateral triangle). I also removed the stock spikes, gold "rings" and replaced with ISOAcoustics. Those guys at ISOAcoustics really stepped up to the plate and made me some custom adapters and extra long bolts. I asked Stillpoints for the same thing, about two months ago and I'm still waiting. I will be interested to try Ultra 5's. The bandpass bass does well with some isolation. I noted some use custom made Shun Mook discs fitted for the feet on the MBL's. I reached out to the rep, but they seem near impossible to come by these days due to the rarity of the aged Mpingo wood.
Hi,
Do you mind elaborating on this a bit? Thanks
Sure. Not unlike the Avantgarde’s, I have spent countless hours experimenting with the MBL’s in terms of side wall placement, front wall placement, amplification, source, toe in positioning, cables, playing with the actual adjustments on the back of the speakers and most importantly, seating placement. I am trying to learn the uniqueness of the speakers and how best to optimize them.
The ISOAcoustics are part of that experiment. They have tightened up the band pass bass considerably and allowed greater clarity and focus in the mids.
Thanks. So what's your take? Long wall or short wall placement? And how close to the walls?
This is a fascinating post - thank you. I would love to hear from M3 owners on this.
Relatedly - I posted on a separate thread, but I noticed a huge difference when playing rock/grunge on my system depending on what the Class A bias was on my amp. In short, the lower the Class A bias (and the higher the Class A/B), the better rock/grunge music sounded. The inverse was true for all other genres. Interesting.
