RE: Neolith has posted Excel Spread Sheet for magnepan speakers

I do not believe they used the midrange QR foil of the 20-series. It is very thin and certainly way off for basses. I guess they may have used the bass QR-foil of the 3.7, it is about the value you mention. Tweeters can use the midrange QR foil of the 20-series but I will come out 7.6 Ohm or so. That is a higher mass than the original I-D tweeter and on par of the I-C tweeter. I understand Magnepan have runned out of the AWG 36 wire originally used (4.7 Ohm). If you have 2 ohm on the tweeters, I think they used a far thicker wire, maybe the midrange wire of the 3-series? The I-D should be 4 Ohm for the bass (two drivers in parallel) and 4.7 Ohm for the tweeter. This can easily be calculated from the wires used by Magnepan. Now you seems to have a higher mass version of the I-D. In other words more like an I-C.
