Yea I read those threads and people get crazy with the science stuff. I have some knowledge of it and have a book all about speakers and sound but am no pro lol. I'd go with the 3015's too. The Faitails sound too hi fi to me. That's the main reason I was never interested in a fearful or new light weight cab cause every clip I've heard they sound too modern. I love me that sound of an old cab before they had computers to tell us how they should sound
