I have an Ashdown MAG 300 head and an Avatar SB112 right now. I would like another cabinet and my preferences are another SB112 or save up for a 4X10. I like the rich and thunderous bass tone of the SB112 and I have all the punch I want already. I would like to keep the tone I have now but want more volume. I'm wondering if having a 4X10 instead of another SB112 would still give me nice bassy low end like the one SB112 I have now. I've never played through a 4X10 so could you tell me how the tone of two SB112s compares to one SB112 and one 4X10?
