Maggies moved 6 inches...big improvement


I have never found that my Maggies are so sensitive to positioning as suggested by many users. Perhaps it is because I have three (not two), the room is very asymetrical, and full of randomly placed furniture unlike the dedicated "listening room". I pull them out a few feet from the wall when I am listening seriously, and that's about it.

However, I just moved them about six inches, and it made a big difference. The secret is that I moved them straight up...off the floor.
I have known for decades that Maggies sound best when suspended from a high ceiling, but that option is not available. What I did is put 1X6 oak boards, on edge, under the metal Maggie feet. This raises the speaker about six inches, and provides open space under them. I am not sure why the improvement happens but here are a few ideas.
1. The open space under the speakers.
2. The speaker is more equally spaced to the ceiling and the floor.
3. The speakers being higher, furniture obstucts less.

Cwlondon...I think that it results from being well away from all boundries, walls, floor and ceiling. The best setup I heard involved a huge room (barn really) where the Maggies were hung about 40 percent of the way into the room. (Near the center).

Suspended speakers, Maggies and others, do not move due to playing music. The idea that they do is a myth. Theoretical analysis will show this, but if you still don't believe try suspending a speaker (as I have) and actually observe what happens when you play music. (Nothing).

Suspended speakers can swing as a result of being bumped or blown by wind. For any reasonable length of suspension rope such motion will be at a frequency lower than 1 Hz, and will not interfere with musical frequencies. Compare with the movement of musical instruments which occurs as the performers play them.

Tympanis would be more difficult to hang than most speakers.
Theaudiotweak...The 3000Hz tweeter to which you refer has a voice coil that pushes one way on its dome and the other way on a speaker enclosure. You ask us to believe that it moves the 40 pound enclosure more than the half-ounce dome. Obviously you have never heard of Isaac Newton.

Perhaps you are thinking of the woofer moving the enclosure that the tweeter is mounted in. Although the woofer cone is heavier than the tweeter dome, the mass of the enclosure still dominates.

If you want to worry about HF being corrupted by LF vibration think about how HF (say 1500 Hz) is generated by a mid/woofer cone that is simultaneously vibrating with large amplitude at 150 Hz. I believe this is called "Dopler distortion".

The walls of some speaker enclosures do vibrate, but primarily as a result of internal pressure from the woofer. The vibration amplitude is much less than the cone excursion, but there is a lot more area of the enclosure, and significant spurious sound can result. Heavy enclosure walls, internal bracing, and, best of all, curved walls will stiffen the enclosure walls and solve this problem.
Aball...Tilting them back, which is usual practice, does not open up space below them. If you had occasion to lift a MG1.6 your concern about a "frail frame" would disappear!

Albertporter...Your comment suggests an amusing game. What form of execution is appropriate for different speakers? Hanging is indeed appropriate for Maggies...speakers for the common man. Bose should be strangled. Your Megalines, so patrician, should drink hemlock.
Theaudiotweak...Tympani 3a's would be hard to hang. Sometime when you have the appropriate speakers and listening space (a barn would be good) try hanging them.
Albert...I have listened extensively to suspended speakers. How many people who criticize the approach can say this? By the way, have you?

Incidentally, a three-chain suspension would provide the same "coupling" to the ceiling as happens with cones to the floor. In some houses the ceiling may be more stable than the floor, especially when people walk around.
Theaudiotweak...Not with Maggies, but I used to play that game with boxes.

Ketchup...I can only guess why people think that.
You are correct that a small force, applied for some time will move a hanging object. But we are not moving it but moving it back and forth at audio frequency. Not the same thing. By the way, if I push my MG1.6 and then let go it rocks at a natural frequency of about 2 Hz. If a Maggie could respond at 2 Hz you might be able to get it going. But they don't.
