Magnepan 3.7's versus 20.1's?

I don't like the concept of non bi-amp capability as designed in 3.7. The Magie is believed to sound best with bi-amplification especially the true ribbon is perfectly matched with class A amp. The separated bass panel from mid/tweeter is a good concept. I am still wonder, even the 20.1 would be comparable with the combined Tympani IV/MGIII which I currently use.

S_c123, there's someone on the Planar Asylum who's putting together a system similar to yours, Tympani 1-D bass panels + MG IIIA's. I'm sure he'll be pleased to hear that you've gotten such good results. I'm curious though -- why did you combine the III's with the IV's, which already have a dedicated mid and a ribbon? Are you crossing over lower down for a 4-way, e.g., at 80 or 100 Hz?

I have a pair of IVA's myself, and plan to run them with the mid/tweeter panel separate because of space limitations. But the crossover is higher, about 300 Hz. I'm also planning to replace the midrange of the IVA's with BG Neo-8's, which are push-pull quasi-ribbon planars. Satie on the Planar Asylum has done this with his IV's and says the quality is comparable to the 20.1's.

The 3.7 lost its bi-amp capability because of the new crossover design, which is apparently first order. If it's like the 1.7's, it's also a series crossover. You could of course go inside the speaker . . .

The 20.7 has been given a mini review by JH on the TAS website. Expect an introduction at CES 1/12. For those who suggested it wouldn't happen, it did.

Yep. However, it was never a question of whether it would happen but whether it would happen this year, and initially even Magnepan didn't know, because they didn't know how long it would take to improve the 20.1.

Still, who was it whose dealer told him it was coming several months ago? And someone else said no, it was going to be a new Tympani? He's officially the winner of that debate, heh.

doesn't matter who guessed what; what matters is saving up enough dinero to buy the 20.7s.
