just got a pair of mmgs. love them but i hear mid bass boom on material with alot of bass. will this go away when speakers break in? will the mye stands or sound anchor stands make it go away? i hate to send these back but i really don't like this boom. it only happens on maybe 10 % of recording, but it is there........thanks

I am presently using a pair of the same and to be honest aside from room resonances experience these speakers are noted.... to have a limited low... end response. If you look at the curves of most speakers there is a rise , or resonance peak located at the lower end of the frequency response. Many speaker designs try different
methods to eliminate this through damping ( internal).
Take a look at the curve of the MMG. Notice the low end cut off at
say 60 HZ. Well let's say that would be 30 HZ on a larger maggie or larger direct radiator based system. On the larger system this resonance peak might be in the 40 HZ range or so and not really noticed as easily.
On the MMG this peak is around 80 HZ , your mid bass boom region.
Room damping and placement as well as any tone control use can
exagerate this to a maximum. FYI many bass tone controls are centered
in the 80 to 100 HZ range.
All speakers have their limitations this appears to be one of the MMG's. To be honest the rise in the mid bass is no more than many competting higher end direct radiator bassed systems. Mine compared roughly to a pair of Soliloquy 5.3's in this same range IE mid bass..
Just my 2 cents...
just added a rel 108qe sub to the mmg's. where should i set the crossover on this sub to get seamless integration?
need both of these for my mmgs. which would make the biggest difference? running with my 40wpc el34 tube amp. seems like plenty of power but now i'm thinking now that the tubes this may be causing the bass boominess......
All tubes are microphonic to some degree, so it is possible that your tube amps are suffering from acoustic feedback through the tubes themselves. However, even solid-state amps can have a similar problem from flexing of the chassis where it supports the power transformer. I had an InnerSound ESL-300 amp that had this problem.The power transformer is mounted on the bottom plate, which is sheet steel supported only at the edges. The transformer is quite heavy, and would bounce up and down like a Sumo wrestler on a trampoline. I discovered this by accident. I had the amp on the floor and thumped the top of it while holding my other hand on the floor. I noticed a pronounced and extended flexing in the (suspended) floor next to the amp in response to the thump. The Bryston amp I also had at the time did not do this. My fix was to remove the stock feet from the InnerSound amp and support it on a thick butcher-block cutting board with a layer of Deflex rubber to cushion the amp bottom plate. The MG-20 bass clarity and extension improved with this change.
Look carefully at how the power transformer is supported in your amp, and how the amp is supported. Any flexibility in the rack, the amp feet, or the amp chassis metal that supports the transformer can cause your problem. Tube microphonics will only make it worse.
That said, you will likely benefit from the ZEROs. Maggies need amps with very low output impedance to damp their internal resonances, and the primary benefit of the ZEROs will be to lower the apparent output impedance of your amp. I can't say whether the Mye stands will give more direct benefit for your immediate problem. If the problem is in the amp, then making the speakers more coherent may make the problem seem worse.
They sounded a little lean and bright, in stock form, in my room. It probably is your speaker placement, but if you happen to have an amp with a very low damping ability, that could also be a factor.
It's really not mid bass... but the MMG's have a bump + 4 to +6dB @ 60 Hz - that is fairly high in Q - that when coupled with a likely room Mode - 60 Hz has a wave length of 18 feet or so. I run the MMG's through a 80Hz 12dB/octave high pass (butterworth) - that is also nicely at the Dolby cutoff for subs....When I first got the MMG's or if I run them by themselves with no sub - I still use the 12dB cutoff - sounds bets to me.
IMO, each Maggie, at it's price point, is one of the best speakers out there. If you can tame the room's "contribution" to the sound, that is.
The MMG, on it's own has no mid-bass peak. Through proper placement & the use of absorber panels and/or bass traps, even a stock MMG will amaze you.
I have the opposite problem, the bass sounds great until I sit in the sweet spot. I tuned my placement for soundstage, but I get a bass suckout in the sweet spot.
Good luck!
You said you tuned your placement for soundstage but you get a bass suckout in the "sweet spot".I suggest the bass suckout is due to either:
* the location of your listening position, relative to the room dimensions, or
* the location of the speakers (relative ...).You might like to try the following procedure:
1. Move your listening position to 1/3rd, 1/5th or 1/7th of the length of the room (away from the wall behind you). [I am assuming here your Maggies are facing down the "longer dimension" of the listening room!]
2. Move the centre of each bass panel to 1/3rd or a 1/5th of the length of the room away from the front wall.
Obviously, there are various combinations of these ratios you can choose from - eg. speakers 1/5th out and chair 1/3rd forward ... or speakers 1/5th out and chair 1/5th forward ... etc..
3. Then adjust the toe-in and distance apart of your speakers to give you the soundstage you like.
Good luck,
I'm buggered!

Sweet goodness, my audio nirvana relies upon my math skills.
Can I call a tech?Sorry, this is totally tongue in cheek. I love these speakers and my room panels give me too much tuning freedom.
I'll work out the #'s. My experience with vibration analysis shows me that the resonances occur along very distinct paths.
This is just a different x value.
Sounds like a placement issue to me.Try different locations with your MMG's to see if the midrange changes.
cooch,
Stands will help, but experiment more with positioning first. I do not have this issue w/ my MMG's, but have heard how placement can often fix it.
Good stands should sort that out.
