Hey @sputz If you have the funds and don’t care about Di-Pole AMTs, one of the best AMT implementations of the AMTs I heard at a show once, >> Gryphon <<.
The lower models like the Pantheon 3-ways are are not as efficient,
Gryphon Trident, 94db. Likely needs two monobock amps with real current imo,. Large AMT at the center, MTM style configuration like I run with mine today.
