Some really good info there guys, cheers.
I'm starting to lean towards the 1x15 as I really don't understand the way the speakers are mounted in the isobaric 212. I just don't get it, but ultimately, if it sounds great, should it really matter if I 'get it' or not?
I know the 1x15 is rated at 400w, is it any quieter than the 212 rated at 600w. Sorry if that is a stupid question, I'm not the most cab savvy, when it comes to the technical side of things.
