Since the Magnepan are dipole I would assume the room treatments would be different. Is there a link out there to give suggested room treatments for dipole speakers? Thank you for your consideration.

I have Carver Platinum electrostatic speakers with the original owner's manual. The manual states the following: The speakers should never be placed LESS than 3 feet from the back wall. The speakers should be placed 6 feet apart. They should never touch the side walls of the room and should remain at least 18 inches away. The speakers should slightly toe-in toward the main listening position. For best performance, the speakers should be placed on carpeting or rug, rather than on a bare floor. Here is a Martin Logan link: youtu.be/ckoqpBmS_mw |

Treatment not placement. Thank you for your consideration.

No treatment on the front wall behind speakers, they count on the reflection. And, because not much energy goes to the sides of Maggies, don't fret about first reflections.

The only room treatment necessary is for the Maggies to be in 'my' room!

As others have stated here, with Magnepans and most other dipole speakers, the rear wave reflection is a part of the speakers sound, and is supposed to be used not absorbed. I've owned multiple Magnepan speakers for over 40 years, and have never needed any sort of room treatment to improve the sound. Placement is the key. If you have a room where the recommended placement options are not possible, it may be different, but if that's the case Magnepans may not be the ideal speaker for you.

No treatment on the front wall behind speakers, they count on the reflection. And, because not much energy goes to the sides of Maggies, don't fret about first reflections. This isn't quite true. Maggies benefit from DIFFUSION on the front wall, behind the speakers. This has the effect of SEEMING to increase the reflection time. The general rule is you want about 10ms, which as it turns out is Also about 10 feet. That means speaker about 5 feet from the wall X 2 which keeps first and 2nd arrival confusion minimized. If the OP is serious about his Maggies? I'd suggest going over to Audio Asylum and checking out the section on Planar speakers. This is a HUGE resource with incredibly knowledable folks who are always good sharing their knowledge and experience. |

Except when having them in a very large room, wherein I could get them well out from the wall behind (6' or more), I have treated the wall behind them. That provides much better imaging and frequency response at the cost of some "spaciousness" depending upon the room. I find the 3' rule a little optimistic but opinions vary. I do not like comb filtering; it really bugs me the way the sound changes as vocals/instruments slide up and down the scale. I have usually used absorption because it is cheaper and easier but as leonski says diffusion is really great if you can do it. Planar dipoles do not radiate much from the sides or top/bottom so sidewall as the frequency rises above the panel dimensions (i.e. usually from upp bass/lower midrange on up) so floor and ceiling treatment is less important. FWIWFM - Don (Maggie owner since ca. 1979 and listener well before then) |

Large rooms and Maggies CAN be wonderful. I had some MG-1 panels in a GIGANTIC room once. It was fully 2 stories interior and very large otherwise in square footage.
I placed my panels on a slight riser with the backs of the speakers towards a pair of openings into the dining room. This was sheer luck / genius as the backwave disappeared mostly into that
space and when it came out, provided ambience without direction shifting. In those days I had a Carver Cube of 200x2 which was Just enough power to take the speakers and amp to redline at
the same time.
donh50 I think beat me by 3 maybe 4 years.......

Diffusion on the wall behind your listening position. Done. IF you are seated within a foot or so of the wall behind you, might work. But if you are out even a few feet? I think I'd let it ride for a while and experiment. I sit just off of 'mid-room'. On the wall opposite the speakers, maybe 20 feet or so, I placed a thick woolen tapestry. When I first put the speakers in the room I had an awful ECHO....slap back? The tapestry fixed THAT. |

My room is 40' x 20' x 18', 14,400 cubic feet. I have found that the best distance from the front wall is when I can walk between my 3.6/Rs, and hear no difference in clarity, frequency response or volume as I do. I think that's the point where the direct and reflected sound are equal.
In my room, that's about 4-5', and my listening position is about 10-12' further back.

I actually use GIK 244 bass traps behind my Maggie's 18" to 24" away, and first reflection 242 panels on the sides. I like how they image and give a big clear and consistent sound.

I think that's the point where the direct and reflected sound are equal. In my room, that's about 4-5', and my listening position is about 10-12' further back. That is about the point where the first big nulls from the back wave drop low enough to be inaudible, or at least harder to hear, and other things help make comb filtering less an issue so you get a nice smooth, stable image. In a smaller room, like mine, and in most of the rooms I set them up (mine or others') over the years, they ended up being 2'~3' from the wall behind and treatment really cleans up the sound. I really think they sound best in a large room; in a small room with treatment they provide more of a "near field" listening experience. Not that it is bad; it is very immersive and that is how many prefer to listen. I go back and forth -- the whole "inside the recording" sound gets a bit overwhelming to me at times and I just want to sit in the audience. Spent plenty of time on stage over the years (OK, on the back row, but still...  ) As of a couple of years ago, my Maggies (all seven) are back in storage, and I haven't really spent enough time with my new (Revel) speakers (insane work hours and too many other things happened) but am pretty happy with them. I was afraid I'd lose that "big" front soundstage the Maggies provided but really did not (probably because the Revels are pretty durn tall too), and they do a lot of other things very well. All IME/IMO/etc. - Don |

I switch back and forth between the big Maggies and my PBN Montanas (full range MTM, Scan-speak Revelator tweeters) for a change. Very different speakers; the PBNs are very (92db) efficient, very dynamic, huge soundstage and very extended frequency response. Still, the Maggies are magic so I'll keep both!

Have you considerred Maggie MODIFICATIONS? Easy to do would be Mye stands. More expensive and controversial would be the Peter Gunn take on Magnestand, which comes with a new crossover and very good woodwork. www.indiespinzone.com/magnestand.htmlThough I don't think he does 3-series any more.... www.myesound.comThe Myestands are what I call 'bridgework and not the way I'd go, but the reviews are generally positive and the mod is doable in your house in just a few hours. Countless DIY options, including various damping and crossover modifications....... Above all? Have FUN. |
