I like horns. There is a lot more out there than people think. 90% of the people who own horns and all the other speakers don't post or care to post.
I think the 10% that do post 3 out of 10 do own horns, maybe not AG so much but there are a LOT of Klipsch, Altec, WE, Imperial, and DIY. The comment about the Horns and Japan, it was the same here. It's just who you hang out with.
I was into making all these weird horns and loading them in a folded baffle, la-te-da. Way over 20 years tinkering, still do from time to time.
The simple answer is horn guys hang out with horn guys. Planar guys hang out with planar guys. Mcintosh guys hang out with Mac guys.. Maybe.. LOL
The common thing between all of us is suppose to be MUSIC, how we get there, that is a personal preference.
