<---not a fan of Big 3 gimmick. I apologize if this comes off as thread bashing but majority of the public has no need for it
I only see relevance for those who utilize an H.O. alternator. But at that point I still don't see why anybody needs an H.O. unless they're big into SPL bass competitions. However, those kids do better with batteries than an H.O. Design and efficiency of the speaker+box plays a big role too. Some guys can be real slick with just 1kw.
Maybe we need to make a list of what/who benefits from Big 3?
