Magnepan MG12/QR Speakers - Review and Observations
Magnepan MG12/QR

Configuration/Specifications
Setup and Placement Flexibility
Getting the MG 12/QRs set up right took some doing. Placement is absolutely critical. We were splitting inches to get them positioned with symmetry to the room and to the Listening Position (LP). They ended up angled straight on axis with the listener's ears. More than once we had them "close" and decided to take measurements again, and a seemingly insignificant symmetry adjustment would significantly change the soundstage.
There was no reason to be concerned about off-axis frequency response sacrifice. They were dead-on-axis or nothing sounded right. Think digitally when setting up Magnepans, the setup is right or it is wrong, there is no in-between.
Our final positioning had the Magnepans spaced very wide in the room. We tried out a more typical narrower positioning and ended up with a soundstage that had little width or depth, and that did not satisfy our predetermined goal.
Final placement measurement from front center baffle of speaker: To Back Wall = 7'8" | To Side Wall = 5'2" | Spkr To Spkr = 9'2" | To Listening Position = 7' | Toe-in = 30°
Frequency Response, Bass Extension
The MG 12/QRs are fairly flat above 250 Hz. There is a broad peak at 2 KHz that emphasizes detail, then a gradual downward trend above that, but the overall treble profile is fairly bright. Below 200 Hz there is a step down giving overall bass levels that are slightly lower than flat, with peaks at 75 and 45 Hz that lend strength to certain bass tones. Bass response extends to 40 Hz.

Power Handling
The genie's deep voice in Three Wishes caused a bit of breakup at one point, just a short splatter, but enough to be a distraction. A fair test? Set up with a solid subwoofer and crossed over at 60 to 80 Hz, it never would have been an issue, but we had our priorities set, made our notes, and forged ahead.
Evaluation Panel - Thoughts and Comments
Wayne's Observations:
Impressions
When first hearing this pair of "Maggies," different descriptive words came to mind than usually do when I am evaluating speakers, like:
At 85 to 90 dB listening levels in our room, the MG 12/QRs stayed super-clean and ultra-transparent, like the window you walk into by accident because you could not see it was there. When pushed beyond that, there was a slight sense of strain, but that might have been our Rogue power amp's tubes running into soft clipping, too. The MG 12/QRs are power hungry panels, as is magnetic-planar technology in general, so they benefit from power amps with lots of headroom. I give them high marks for clarity at the volumes levels we were using the most.
The splatter from the genie's voice had me wondering if such inefficient speakers could handle a larger room deadened by acoustical treatments the way ours was. But the dipole flat panel design needs some space to be at their best, so this is the application they were meant for.
Soundstage and Imaging:
The soundstage delivered by the Magnepans was wide and deep, not the best we heard, but NICE, very clear and cohesive and extending beyond the speakers in width.
Some speakers can create a large soundstage that feels pieced-together, a mosaic of little soundstages that do not quite fit, failing to create the illusion of another space being delivered for you to explore. The MG 12/QRs presented a seamless soundstage with ease.
While slightly soft, imaging was very well behaved. The tweeters are vertical strips in the planar design positioned on the outsides of the panels, and I thought this might lead to the treble sounds on female voices sounding wider than the rest, but that never occurred to an obvious degree. One of my favorite imaging test tracks is Ain't It A Shame, by the B-52's. Cindy Wilson's voice was recorded with an enhanced sheen that extends to well above 10 KHz. Any frequency or phase mismatching of mid- or high-frequency drivers will have her concisely-recorded voice, alone in the center of the mix for much of the song, smearing to one side or the other, especially on sibilant sounds. The Magnepans kept Cindy's sibilants right where they belonged.
Consistent imaging spoils a listener quickly, making one very sensitive to an individual acoustical guitar or mandolin note that seems wider or slightly offset from the rest. And that effect, if a problem for a pair of speakers, is only accentuated by a widened soundstage. But here there were no wandering images with the MG 12/QRs, every sound knew its place and stayed there.
Just for fun, when it was time to switch out the Magnepans, I moved them in close to the LP for a near-field listening test, totally unfair for that kind of speaker. The result? Not bad! Imaging was certainly more dispersed, the soundstage very contained. A very closed-in delivery in contrast to what we had just heard from them. All in all, probably better than you would expect from flat-panel dipole speakers up close. But they were not at their best and I am certain this would not be recommended by Magnepan. The experiment underscored the MG 12/QR's need for space to develop their sound.
The listening position sweet spot for these speakers was pretty tight. We could adjust a little for comfort and not lose the soundstage, but it would change a bit, and it moved around when we did. Narrower spacing and a shallower soundstage might be preferred by those who want more sitting position flexibility.
Frequency Response:
The mids and highs were a bit forward, but with a smoothness that was not fatiguing in the least. In fact I found it a bit exciting, as though I had been given the ability to drill deep into musical detail.
Low frequency strength was adequate for me, perhaps slightly on the weak side. I generally prefer a flat EQ, so I am not looking to be shaken by kick drums or bass notes. The MG 12/QRs are known to perform best with a little help from a subwoofer, which I could see the benefit of at times, but I did not find the bass disappointing.
The kick drum on I Don't Care Any More by Phil Collins became one of our low bass measurement standards, as did the deep voice of the genie in Roger Waters's Three Wishes. In those cases, the Magnepans were a bit lacking in depth, but for the most part did just fine to my ear.
Our averaged frequency response plot at the listening position shows what almost looks like a step down just below 200 Hz, then a peaked response below that. The lowest peak is at 47 Hz - not bad for a panel this size - and when a note got hold of that frequency it thumped us pretty good, but there were those dips at 60 and 90 Hz where other notes got lost. I still stick with adequate in describing the bass, for those who are not bass-hungry. A bigger bass appetite will certainly want a subwoofer, if that is an option.
Physical and Visual:
Magnetic planar speaker technology involves a large, lightweight membrane that does not have to move much to create sound at listening volume. It is the nature of the design that leads to that sense of quickness and responsiveness. The large flat panels are equally open front and back, a dipole design that keeps the sound in front somewhat beamed at the listener and reduces room interaction, except for the need for lots of space behind them.
Magnepans do not look like typical speakers. Their panel design is simple, elegant, modern, and very minimalist. I enjoy a good techie look in speakers, even the outlandish, but I was drawn to the elegance of form and function of the Maggies.
They are very light and easy to move, which could be an advantage to some listeners. Sonnie's intention for his home theater was to choose speakers that could be set aside for cinema and could be easily placed in position for music listening. The Magnepans got high marks both for being unobtrusive and easy to get out of the way and for being easy to move into place when needed. The need for critical positioning is another matter.
Overall Listening Experience:
Listening to the Magnepans was a treat for me. More than with any of the other speakers, I found myself wanting the chance to sneak off for a good long private listening session to really find out what they were made of. I especially enjoyed our acoustical test tracks. Nickel Creek's Ode To A Butterfly, with guitar, mandolin, and fiddle, had lots of detail to explore. The standup bass notes were treated somewhat unevenly, a slight distraction.
More complex, heavier tracks received good treatment, too. The B-52's Revolution Earth sounded wonderful, as did tracks by Pink Floyd and Roger Waters, minus the incident with the genie's voice. Other evaluators were listening for more and deeper bass, as their comments will reflect. If your tastes are for flatter bass, the Magnepans might suit you perfectly.
What These Speakers Are Best For:
Wonderfully transparent, the MG 12/QRs will handle all the complex material you can throw at them. They will perform best with proper support: lots of clean headroom and a subwoofer if you want heavy, deep bass. They are the kind of speakers that like to point out flaws in one's favorite recordings. While this can frustrate some listeners, I love hearing that level of detail.
Leonard's Observations:
Once positioned, the MG12 has a superb soundstage and open sound. The positioning took quite some time but once the ideal spot was found the image was well defined and stable. Moving the listening position forward and back, left and right by about a foot did not significantly change the perception of a soundstage and instrument location. The planar design certainly has an appeal, very open and “out of the box.” The downside to this speaker are the power demands and the lack of bass. I felt no listening fatigue on any of the music we used, but the speaker did not excite me nor beg listening like the preferred speakers in the comparison. Not in the top tier of the products we auditioned, but likely the top of the next in my opinion. The dynamics were strained, probably needing more power, and for full range listening I would love these with a sub. I have always been partial to Magnepans (sold them back in the early days of the product) and planar speakers in general, but the reality is that you have to have the right conditions to get the best out of them, more so than some of the other speakers we heard.
Sonnie's Observations:
The MG12’s were the first up for evaluation and it took quite a bit of moving around to get these placed in that perfect sweet spot. I wondered if all of the speakers were going to be this difficult to position... and if so, we were going to be in for a long evaluation process. They look very nice, no doubt unconventional, which suits me just fine. They are also easy to move around... and would be the easiest to move out of the way during home theater use. I kept thinking to myself that I would really like the MG12's since they are a planar speaker, and the fact that I really like the MartinLogan line of electrostatics for my home theater. As I sat down in front of them and began to listen, I was impressed right off the bat. My first thought was that we have set the bar extremely high, especially for overall imaging and clarity. The MG12's also produced a pretty good soundstage that I thought was extended and deep, however there was no doubt they suffered from a lack of the lower octave of bass from 40Hz down.
On Melody Gardot’s Baby I’m A Fool, imaging was good enough to place the orchestra lower down in front of me and in front of the stage, although her voice seemed larger than life. She was just ever so slightly left of center, while the acoustic guitarist was a little right of center sitting next to her and seemed like it was coming more from behind the orchestra than her voice.
With Nickel Creek’s Ode To A Butterfly the imaging was spectacular to say the least and the soundstage was big. The mandolin was clearly left of center stage, the fiddle was middle of the stage, with the guitar right of center, all on the front edge of the stage (the MG12’s really disappeared with this song)… but what was perhaps most defining about this song was the deep bass being behind and between the fiddle and guitar. The depth was incredible on this song.
Pink Floyd’s Dogs Of War is where I could really tell the lack of bass, it just was not there, and this song does not sound right without it.
While listening to Roger Water’s Three Wishes, one of my favorite demo songs, at 2:25, where the genie's voice kicks in, I noticed a grunting sound. I backed it up a few seconds and sure enough, the MG12's were straining on that part of the song. Of course at a lower volume it was not as noticeable, but at the listening levels I like, the MG12's could not handle it.
Again on Yello La Habanera, the bass was missing, as was the midbass impact that I am use to hearing in this song.
There were definitely some great characteristics I liked about the MG12’s, while they suffered in some other areas. I suppose I should mention that the sales manager at Magnepan even went so far as to suggest that he did not think the Magnepans would fair so well in this event due to their lack of bass. However, I have to contribute their most significant shortcomings (grunting) to a lack of power. As sensitive as these speakers are, they really need more power than we were offering them. I think if I were to keep these, I would want to pick up an Emotiva XPA-2... and of course a sub would also be required. I certainly do not believe these speakers are suited well for lower powered tube amps with the type of music I listen to.
