The results using these methods compare favourably with my NRC measurements of the same speakers and in some cases, they are actually more accurate due to M37's single position low frequency calibration.

Hey Mark, how are you? It has been a while. Hope to see you in the next meet. It would be great to have a speaker expert in the group

Well i’m not sure of the phasing on the shop speakers at the low to mid @ 250hz crossover point and mid horn is definitely delayed because of horn length, so a test system would be greatly appreciated, but it would be better utliized if others had speakers they’d like to test as well.

I have a Mac Mini with Amarra and Dirac ( digital inverse speaker equlization) installed and a calibrated mic, but haven’t tried to use it yet, maybe I’ll figure it out for this meet.

A new 24/192 DAC should be there, some new HD downloads, new tweeters too. Hmmmm i better fix my power amp too..........
