What is the difference between the sound of a 4 x 10 and a 115 and a 2 x 10 and a 115? Will I still be able to get a low tone? I want to get the 4 x 10's because I hear that they are punchy and clear. I was thinking about purchasing a 4 x 10 and a 115 rig, however I have never played through one. I'll make my way around to trying one out before I buy it, however I would like to hear what you have to say. I want to get an avatar 4 x 10 and a 115 but I am not sure what head I should get. If you could help me out, I would apreciate it.
