| 4x12s will let the resonance of the drivers and the cabinet pull up a lot more (you get that little "umph" when you are running your drive channel(s) ). But a 2x12 will (in all theory) will allow you to use the bass knob a little bit more without getting loose.
In my opinion, a set of bass heavy speakers (greenbacks, or fanes) in a smaller 2x12 sound awesome. |
