In Reply to: RE: Room size ? posted by peppy m. on December 20, 2024 at 11:59:50
Thanks, Peppy. Not sure about that. They are 44" tall and have 8" and 10" woofers. My listening room is 20x26. My listening position is in an 8' equilateral triangle with the speakers about 7' into the room.
I have managed to load the room to 104dB with them playing electronica, it is just massed strings that seem to be an issue. It is very weird. Or maybe I am very weird. ;-)

I often have problems with massed strings, too. It might be the recording. Have you ever heard massed strings sound good in a different system from the same recording? If so, what speakers and amplifiers were being used in that system?
I recently discovered Magnepan magnetic planar speakers, and they sound better to me than other speakers I've owned. I'm currently using Mini Maggie speakers with 500-watt monoblock amplifiers and they sound spectacular. Nevertheless, I still have orchestral recordings that don't sound good to me. On the other hand, I have other orchestral recordings that sound great. Therefore, maybe it's the recording that doesn't sound that good.
Anyway, I like these Mini Maggie speakers so much that I'm considering buying full-size Magnepan speakers.
Happy listening!
In the photos I've seen so far, your room looked pretty small.I used to own Maggie 1.6 speakers about 15 years ago, and I had problems with excessive mid-bass in rooms too small for them. OTOH, I couldn't afford enough high-quality power to make them sound good in much larger rooms.
Good sounding power has gotten a little cheaper since then, thanks to advances in Class D designs. But the excessive mid bass problems might still be there (for me and my smallish room) today, if I went with anything bigger than the Mini-Maggies (or possibly, the .7 model)...
If your room is as small as it looks in the photos I've seen, I'd think about trying out the "medium-sized" .7 model. The bigger models might cause you some problems.
For subwoofers, I'd think about using open-baffle...

My listening is 19-ft long by 15-ft wde, but there's a dining room and galley kitchen on the side. The kitchen is separated by a partial wall and a counter while the small dining room is completely open to the listening room. The ceiling goes from 8-ft high at the rear to 14-ft high at the front of the room. My speakers will be set up on the diagonal just like the Thiel's in the picture below, but they will be farther out into the room and farther apart. My sofa will be set up on a 45-degree diagonal facing the fireplace, TV and speakers. I think the room is large enough for the new Magnepan 3.7x speakers. The sofa in the picture below is gone completely, and I have a new sofa set up behind the black chair, which is also gone.
It's about the same height, but a little bit narrower, but still has a true ribbon tweeter, which is a very good thing to have, as you should know from your Mini-Maggies. Also somewhat less expensive.

1.7i is around 6" narrower than 3.7i. Noticeably thinner than 2.7i or 3.7i, but still quite wide...
A pair of .7i or.7x (plus GR Research open-baffle subs ?) is the true "space-saving" option.

To some of us, 1/12th is a lot , since it's a semi-tone. Wow, talk about being out of tune! Not a little sharp or a little flat - that's a whole different note!
Sorry, just had to write that. ;)

To me though, 2" is not enough to matter. Mattering starts at 5" or 6", IMO...

That's a good recommendation. I think you might be right. Perhaps the 2.7i might be the better choice for my listening room.
I just noticed that Magnepan has a new line of speakers with an "x" designator instead of the "i" designator. The new line of speakers have high-end crossovers and gold plated connectors. The Magnepan 2.7x costs $10,000, and I think I'll probably spend the extra money. However, I have a feeling it might not make that much difference in sound, if any.
What do you think about the 1.7x for $5,000? It's stated to be a 3-Way,Full-Range, Quasi-Ribbon speaker just like the 2.7x. Does it also have a ribbon tweeter?
Thanks,
John Elison
as I understand it, a single strip of foil conductor on the QR tweeter that is crossed over fairly high and acts as a kind of "supertweeter", the advantage presumably being that it gives a little bit better dispersion. But it's not going to have the same extreme lightness as the true ribbon, and therefore isn't going to have the same extension and resolution. And, if I'm not mistaken, there is no LP crossover on the rest of the QR. None of this is to say that it's going to sound bad, though.
Opinions about the "X" versions seem to be all over the map.

The 3.7s would sound nice with their true ribbon tweeters. Just like your Mini Maggies... but gigantic.I know you already have nice subwoofers, but you might want to consider one or two of those DIY GR Research open baffle subs for the most seamless blending of sound... if in fact you'll need subs at all with those big panels.
Have fun, good luck !

The 2.7i is slightly smaller and the 1.7i is even smaller still. I'm thinking about one of these other two models instead.
Thanks,
John Elison
just give them room behind to breathe. Heard a nicely driven pair in a smallish room.

I really want the 3.7x speakers. If I could get the 2.7x speakers with flat bottoms like the 3.7X speaker, I might consider them. Of course, I want the true ribbon tweeter, whatever that means. I don't actually know what a ribbon tweeter is, except that everyone thinks its better. ;-)
The smaller ones tilt back or stand completely vertical. Aftermarket stands are available to raise and tilt all models backwards.The 3.7i is already tall enough to sound "room-filling" as-is ? And are heavy enough to fall over if tilted back... I guess ?
Anyway, it appears that Magnepan might prefer that the 3.7i speakers would NOT be tilted backwards...

Part of what has to move with the mylar diaphragm with Magneplanars is the conductive wire. Ribbons avoid that.

How do ribbons avoid that?
I know that Magnepan's have copper wire glued to their mylar diaphragm because I took the cover off a pair some years ago. Some of the wire had broken free from the diaphragm. However, I think some of the new Magnepan speakers might have aluminum foil attached to the mylar diaphragm instead of wire. I thought I read that somewhere, but I can't find it now. Have you heard anything like that?
Thanks!
It's used in the bass and midrange sections of the three-way models, and mid/bass and tweeter sections of the two-way models.

Although, I don't think the term "quasi-ribbon" refers to foil conductors instead of wire conductors. I think it simply means that the diaphragm has conductors glued to it, instead of being a true ribbon. My Mini Maggies have wire glued onto the mylar diaphragms, yet Magnepan still refers to them as quasi-ribbon drivers. Only the tweeter is a true ribbon driver.
Nevertheless, I'm glad they switched from wire to foil, because not only is it probably more reliable, it probably has lower mass, too. I just hope it can still handle the current as well as wire. It would be nice if they used silver foil.
Thanks!
No, the "QR" designation applies specifically to the method of using foil glued to the mylar instead of wires. They came up with the term to differentiate it from the older wire system that was used on both bass and tweeter sections previously. The Magnepan website has explained this since its introduction of the QR technology.
The foil, to the best of my knowledge, doesn't have significantly lower mass than the wires; they kept it the same because the impedance needed to stay the same, but it probably has a bit lower distortion because the foil is adhered to a larger area of the Mylar than the wires are.
I've read discussion in the past on various forums about using other metals as conductors, but the consensus has generally been that aluminum has the best combined mass/conductivity characteristics.
I've been a Maggie guy since 1998, and it's been head-spinning to try to keep up with all of their changes in methods.

the foil is conductive. Not sure. The 20.1s and 3.7s I've heard had a really sweet top end. The earlier "dot ones", however, sounded to these ears like a collection of separate drivers.Click here for a general diagram and terminology.
You'll get detailed answers over at MUG, aka Planar Forum. Click here for more detail from Magnepan.

That's exactly correct. With the true ribbon tweeter, the radiating diaphragm is also the conductor. It's about 5 feet long and about 1/4 inch wide, and is extremely light and thin. It's aluminum foil that is significantly thinner than kitchen-type aluminum foil. The electrical contacts are at each end, but there are small, alternating supporting dots of silicone rubber along its length on each side attached to the magnet structure. The resolution and inner detail in its range are marvelous.

.., for 10 milliseconds of backwave return, a pair would make a great pair of room dividers...Used as dressing screens for the sake of modesty, a change of trousers during listening sessions has never been easier !

that was determined empirically by measurements for the most linear bass in the bottom octaves. A mentor taught me the "Rule of Thirds" placement which I've found quite useful for minimizing room modes.
I don't have that latitude with the smaller ones in the family room, but still walk behind them on the way to the east side of house.
Pics in gallery.
Closer to 20 milliseconds of back-wave delay, and in line with my own findings in "the rule of thirds" for speaker placement.
Should you ever decide the 1.7s are too small, Maggie 1.7 speakers have many fans. So, not very hard to sell the 1.7s to move up to the 2.7.Try to find a local buyer for a home pickup deal in order to avoid box shipping, that's all...

that I'm considering buying full-size Magnepan speakers.
for it!
Even with those large woofers and mids, I'd try positioning the speakers closer to the wall behind them for a weightier sound.
The suggestion to contact Vandersteen for best speaker size and best placement recommendations etc.., is a good one.
