Title: Has anyone tried stacking Maggie's?
Post by: capwkidd on 17 Aug 2013, 07:16 pm
Perhaps, stacking super MMG's with a couple of DWM's?

Ok, the reason why I ask, is to get the height.... I see that the taller the planner the better I like it :)

I asked about stacked MMGs some time back, Magnepan had tried it (or course) and I'm told it worked well.

What are you using for a system at the moment?

Using some Nola Contenders.... I have a few other speakers, but those are my favorite.... But now I have the planner bug :O

I guess the ideal thing to do would be to get a pair of Soundlab M1's AND Magnepan 20.7's..... Sigh

Just looking for the biggest image I can get with just the right amount of bass output :)

You'd better have one heck of a large room for those guys.
I loved the 20.7s but just didn't have enough space for them so off they went to an audiophile in California and in came another set of 3.7s.  I added a sub at low volume and it's just perfect for my house.
If I had another 6' in length and 6' in width for the living room I'd still have the 20.7s but a major home renovation like that would entail is not in the cards.

Ok, how big is your room then?

How does one determine what size plannar they can have? My room is 11.9x16.2, the dining room is off the long end, but there is a wall cutting in about 5'.....

Around 24x14'.
You're going to have way too much bass with the 20.7s.
I'd go 3.7s if I were you.

The 3.7s did not sound that great to me.... maybe the tweeter was attenuated too much.... placement seemed ok.....

Post by: SteveFord on 18 Aug 2013, 04:12 pm
They're not the only brand out there so maybe Janzen, GT Audio Works or Martin Logan would be more to your liking.
I can tell you that it's easy to go too big for your room.
The ribbons on the 3.7s can clean the wax out of your ears on the right recordings with a Sonic Frontiers preamp...
If they had those attenuators plugged in that will make them sound weird.

About 15-16 years ago I borrowed a set of Sound Labs to A-B against my stacked DQ-10s/Sequerra ribbons.  Don't remember what model they were but the sounds in my room were almost identical, except for a HUGE standing wave from the Sounds Labs that floated in the air for what seemed like ten seconds.   :o

I knew nothing of standing waves, speaker placement or any other tweaks so the SLs quickly went back to the seller.  Martin-Logan Quests also flopped in the same room.  When I tried Maggie 1.6s in the same room and same spots the improvement was enormous; MAGICAL, if you will.  Now I'm nicely settled in with a pair of 20.1s. and all the others are gone.   :thumb:

Martin Logan are out because they all sound wrong to my ear (I have not heard the newest ones, but they use the same panel, so...) .... Janszen I heard at THE show in June, but I guess I did not get a good enough listen... But I like the huge/tall sound of large panels.....

GT audio works.... I have seen some pics.... But don't know if they are worth thing to listen too... Any opinions? Do they have a tall/big sound to them?

GT Audio had 2 rooms at the DC AudioFest.  I'll be honest, I did not enjoy the smaller ones in the room they were in.  The sound was not that tall or the soundstage so deep.  There also seemed to be a peak at 4000 Hz or so which, if EQ'd, might be tamable.  The larger model were more to my liking, but they also seemed to be hotter at 4000 Hz than I'd like, but not as bad as the smaller model.  The larger ones had more of a soundstage, also.  Again, this is my opinion; to my ears my Gunned MMGs are closer to being musical.  The GT's has a hardness to the sound that did not invite relaxed, extended listening.

Again, all this is IMHO.   :)

But, how is the bass on the MMG's once Peter mods them? Or, the 1.6's for that matter? Also, is there a Maggie 1.6 and a 1.6 QR? or are they the same thing? How low do the moded ones go?

Here is one post from a fairly long thread where I detail the benefits of the MMG mod:

http://www.audiocircle.com/index.php?topic=118426.msg1244512#msg1244512 (http://www.audiocircle.com/index.php?topic=118426.msg1244512#msg1244512)

IMHO, it's worth reading the whole thread...   :)  As far as bass is concerned, I measured an extension of usable bass from 50 Hz stock to 45 Hz with the Magnestand mod.  AFAIK, a 1.6 IS a 1.6QR.  Hope this helps.

I can't speak for the Magnestands, but there are a number of aftermarket stands for Maggies that improve the bass definition.  I use Mye stands on my MGIII's and wouldn't have a pair of Maggies without something that provides similar bracing.  Many people have done DIY versions.

If you build a frame and stick two MMG drivers stacked one on top of the other you end up with an 8' speaker about as tall as an Acoustat 2+2.


It should improve image height and the depth dimension as the taller speaker will give you more precise renditions of floor bounce cues for depth. You will also get some minor reinforcement of bass  below 200 hz, and should be obviously noticeable in bass below 100 hz.

I keep waiting for someone to do it and report on the results.

I asked Wendell about that a year or two ago.
They had tried it (what a surprise) and said that it worked out really well.

Did he say if he moded the XO for the change in nearfield/farfield transition and more bass? Any descriptions of the SQ line items and how they had changed?

     The GT audio Works speakers are not hard sounding. I set up the systems at the show. We had some  issues with our initial setup. At first we had a prototype Arion preamp in the main room and it just did not make it as set up. Yes that was a bit hard on the ears Agreed. We had some system issues that were resolved later in the show. Live and learn.
     The GT audio Works speakers are well worth a listen. Great bass to 25Hz.  Soundstage is full scale with precise imaging. Transparent with great presence. So good in fact I ordered a custom pair to replace my Pipedreams. For me the most transparent panels I have yet to hear. IMO only bettered by 20.1 or Martin Logan statement speakers for a lot more money and not by much.
    Read the show coverage by Kemper at enjoythemusic.com.  Not a dealer for GTAW. A listen never hurts.

Now that's a thought - double stacked Super MMGs with 2 DWMs for $2400.

capwkidd, one of the features that impressed me with the Janszen zA2.1 was the projection of a much larger image than expected from a cabinet that size and the number of drivers.  Audio friends who heard the demo pair I tried, or the ones I purchased, in my room made similar comments.

I don't know what the problems may be but from what I heard at THE Show Newport and read of other shows, the zA2.1 has not shown its full potential in those demos.  Hearing them in my own room, plus at a friend's who also bought a pair, is a different experience.

Certainly I can't say if they would project the size image you're looking for, but it could be worth the effort of trying them.

From Wendell:

Stacking speakers into a line source does not require any mods. But, it does nothing for the inherent limitations of the drivers. It only improves the power response.
Title: Re: Has anyone tried stacking Maggie's?
Post by: Davey on 5 Sep 2013, 02:52 am
I don't agree that it improves the power response.  However, some folks have a different definition of power response so it's not worth quibbling.  What it does do is create a 2X taller source and moves the nearfield-farfield transition 2X farther away.  That's probably a good thing in most situations.
I think the main benefit though is for a stacked set of speakers each transducer is only working half as hard to create the same SPL.  (Less distortion.)

If stacking MMG's, I would take the second right speaker and turn it upside down on top of the lower left speaker.....and vice-versa.  This would yield a setup where the ribbon ends are closer (coupled better) together.  Although it's still not optimum.

Cheers,

Dave.
