Does anyone know if there is a site that has professional sound clips of the different Celestions/Eminence speakers? By professional I mean not Joe Blow with a web cam rocking out AC/DC through a Celestion. I'm thinking about getting a different speaker for my Vypyr 30, maybe something with higher power (depends on if I do a 1-12 stack) and would like to hear the differences they're all talking about. Celestion would be 1st choice then Carvin then Eminence. Carvins in 2nd because their GT12 says it compares to the Vintage 30 (and it's $60 compared to $150). Basically a way to do a side-by-side comparison.
