Improvements in the past 40 years?
With the improvements in computer modeling made in the past 40 years, has there been an "improved" 1C crossover designed or is the original design still the best?
Thanks!

AMT drivers tend to be almost purely resistive, so even 40 years ago they would have been very easy to design for. Having said that, a crossover must take into accou t more than just 1 driver. Using Xsim and the right measurements of the two drivers that must be integrated is surely much easier and affordable. A $12 measurement m8c and Room EQ wizard or Omnimic and DATS will be the equal if not far exceed what was available 40 years ago.
I made a slight improvement in sound by replacing the three Heil side series capacitors with Mundorf EVO Oil Aluminum caps. I had to readjust the midrange presence and brilliance controls after that, they really opened the speakers up quite a bit.
I have the ESS AMT limited edition mfg'd in 2014.

Great sounding speaker.
Ive often wondered about switching to an improved 12" full range or change the XO or both.

Frankly I have been wondering how an EVM-12L would sound... but there are a few characteristics that other 12" speakers must adhere to:
1) They must be 4 ohm. If they are not, the XO would need to be modified. Does anyone have a suggestion of how to mod the XO for an 8 ohm speaker?
2) They must have the four flat spots around the edge of the speaker frame so they'll fit into the cutouts in the ESS cabinet... Or use different cabinets.
