Re: Speaker Configurations...
What kind of amp has the 2x10s?
I have a maz jr with 2x10s and I love the sound. The 10s have a really nice thick midrange and don't muddy up the band's sound but fit right in between the bass and the cymbals. 10's are very underrated by guitarists because everyone wants that halfstack. The tens are snappier, especially in a closed back, and that's one of the reasons bassists love them. With an open back they have a special ambience to them that you really need to hear. (tweed bassman or super)
The twelves can pick up more low frequencies and give you the "thump" that you hear people talk about. I'll eventually add a single 12 to my set up for more sound and I have a suspicion that 10s and 12s are the perfect combo. For me and my 18 watts it will have lots of mids, and just enough lows to fill up a club/bar.
