Hey speedbump6,
Congrats! I think you are in for a treat. How big is your acoustic space and what is your upstream gear?

If you love big electrostatic panels, but have a small acoustic space-a speaker for you!
Hello! Thanks for the cool reference. The name means "Truth Audio". I wanted to build a speaker brand that reproduced the transient attack and speed of the original music while keeping costs reasonably affordable. It may seem a bit odd to marry a 4 inch driver with a Heil AMT but the speed and light weight of the Fostex driver at under 4 Grams matches the diaphragm speed of the Heil. They hand off to each other at 2 K which maximizes dispersion and widens the listening window. Full range drivers in general tend to beam as the frequency advances beyond say 2 Khz. |
Nice. Great to see it! 40 years building with the Great Heil AMT. I worked at ESS building them on the assembly line. Built several custom versions since. Prefer crossing over at 1,200hz vs 2k to retain Heil midrange magic. Listening to my custom DEC-AMT28 speakers right now with QS Mono 120 Tube amps. :) And, former low watt triode and strapped triode tube amps too. May retest other lower-watt MOSFET SS amps again with Great Heil. FYI, other custom AMT builds by members on AudioKarma, here: https://audiokarma.org/forums/index.php?threads/custom-built-ess-amt-heil-based-speaker-thread.57722... |
