Magnepan 3.7

Weseixas,

The Maggie tweeter ribbon is actually 3 ohms, owing I think to its length and thinness. Here's a schematic of the 3.6:

I think Apogee's ribbon mids had such a low impedance because they were 3" wide.

>Josh358, Yankee ribbon has a true "ribbon woofer" ....

That's interesting. How did they do that?

>The magnetic assembly is what determines if it is a true ribbon or not , not the type of diaphram,

You have a point, though I'm thinking that technically it's based on whether the diaphragm is shaped like a ribbon or not (attached at two ends rather than at all four sides). So the Apogees mids mylar backing would still be considered true ribbons, even the ones with three traces.

Of course, since true ribbons are narrow, the magnet assembly changes too, since a side-by-side arrangement has a field that's more linear with displacement. As I understand it, 3" is the maximum you can do that with practical magnets.

Also, as I understand it, at least some ribbons have low tension to put the vertical resonance below the driver's frequency range.

Stolen thread and all, Interesting. As for a foil ribbon tweet, yeah it is great, except if you sneeze on it..'poof' no more ribbon (that works, anyway) if you keep from moving enough external air to pop the ribbon, all is well.
I own Magnepan 3.6s i bought new nine months ago. I love them. I had some Infinity RSIIa and liked the dipole a lot, had them almost twenty years. Then some box speakers.. ahhh glad i went back to a dipole, and I like my Maggies, delam or not. But never know I might buy the new 3.7s... sigh..
As for the two issues: delam. Delam has NOT stopped Magnepans from having one of the highest resale value. Delam is a PITA, but repair can be done dirt cheap, or send them to Magnepan for repair.
And making them better: If they made them so they would please the perfectionist build quality freaks, they would cost three times what they do. So I have no complaints about build, as they are considered to be one of the best values at thier price point around,(and is probably why they command such a high resale value)

I know the feeling, but at times like this, it's important to remember that despite the raves that accompany any new model, improvements in speakers are incremental! After all, there are still a lot of people enjoying IIIA's. Which is why they hold their value so well, there were a lot of 1.6's for sale after the 1.7 came out but the used price dropped hardly at all. Hell, my 1D's now go for more than I paid for them in the early 80's!

Has anyone heard it at this past week?
