Magnepan announces the 20.7

without getting into controversial territory, it is clear that Maggies are a DIY dream come true.
Stands? have fans Crossover mods? for sure Bi/Triamp setups? absolutely Active vs Passive crossover? yes Full wood reframe? on the table Sound damping? You should see the posts!

So, the Mye stands are just the tip of the 'berg. The overwhelming opinion is that panels, which are built to price constraints, benefit from any number of DIY projects. All have fans.

Not that is matters, but even if they DO help, I'm not a fan of bridgework stands. Too much metal, which rings. I'll go with a full reframe, when the time and finances permit. A good, solid, Mahogany should work wonders and have many advantages over the MDF which is stock.

I think you can pour sand into the Mye stands, I imagine that would do a good job of getting rid of any ringing.

It's worth noting too that both YG and Magico use aluminum enclosures. Apparently, it's easier to control the ringing than it is to damp wood. (Of course, enclosures are more demanding of the material than frames.) Jim Winey is on record as having said that metal frames would be better for Maggies, though I don't think they're a practical DIY project for most of us.

Another possibility is Corian, some dipole manufacturers say it makes a better baffle than wood and MDF.

Josh is well aware of the 'third rail' nature of talking about panel vibrations and the various theories.

Magnepan vibration theories abound. Wood perhaps absorbs vibration which may 'reflect' back from the MDF and cause problems. That's why I'm not a big metal fan, too, since metal will reflect vibes.
At least Aluminum doesn't ring like Steel. And most of what I don't like about Aluminum wouldn't matter using it in panel construction, anyway. Lack of fatigue strength and poor tensile strength, for example. Don't bother telling me about special Aluminum alloys. I suspect Magico uses a 6000 series since it is easy to work.

I'll bet Corian would give your budget a hernia.

Didn't like the 20.1's why would I like the 20.7's?

I have listened to Maggies going back to the 80's and as recent as a few months ago (with top of the line ARC gear). I appreciate their speed and their light airy soundstage. Their sound is similar to the Quad ESL's to me with the Quad's being just bit more magical. Still, I come home and hear my system and find it more satisfying. Maybe not quite as fast, but there is more meat to the sound, more heft. The Maggies soundstage is impressive, but always seems semi-transparent whereas my home system makes the soundstage more solid feeling. I like them, but just never enough to put out the cash to own them. The Maggies do a couple of things exceptionally well, but I would not say that they are the best speakers ever- even at their price point. To each his own.
