I think this is a fantastic idea. The more you are exposed to different systems, the more you learn. I've certainly learned a lot since I first heard a properly setup Altec VOT and then another horn system. My system is a biamped 15" woofer crossed to a large format CD on a tractrix paper horn at 600 Hz. Lately, I've experimented with mating a SEOS12 at 4 kHz to improve dispersion in the top frequencies. I'm at Richland, WA. The chances of someone on this forum living near here are pretty slim. But we are within 3 hours from Seattle and 4 from Portland. So, give me a shout if you want to meet up and have a listen. bwaslo, I really want to hear the coSynes. They seem like the next step from regular horns. I will try to make it there sometime. Thanks for the offer.
