Re: Blues Amp 2x10 or 1x15 ?
The actual physics of speaker configurations can easily get over my head, I usually leave this stuff to the scientists among us, but I heard something pretty interesting the other day.
It actually came about when discussing PA's. Myself, my brother and my Dad were talking about the pro's and con's of different sized bass bins when, I think it was my Dad that mentioned something I'd never thought of before. Basically, the smaller a speaker the less frequencies it will attempt. Which is when flabbiness happens.
To some extent a 10' speaker will just ignore the frequencies that can cause muddy bass in bigger speakers. We talking the absolute bottom of the audio spectrum here, I'm not saying 10' speakers won't register your bottom E string or anything! I'd always just assumed that bigger meant more bass, which to some degree I suppose it does, it just doesn't neccessarily mean BETTER bass.
I don't know how this translates to blues amps, I'm not much of a blues player to be honest. But I guess in general it just comes down to what sort of bass sound you're after. If it's boomy, earth-shattering stuff then the bigger the better as far as speakers are concerned. But if you want tight, focused bass then get smaller speakers. Of course you can't just concern yourself with bass response when you're choosing your amp's speaker configuration. This stuff translates to all other frequency bands as well.
I've only ever owned guitar amps with 10' speakers and I can't imagine that changing any time soon. You can't get the same sort of focus and clarity from anything else, but to some extent I do think you sacrifice gutsy power. You just have to decide which is more important to you.
