Hello, I currently am running a Peavey Combo 115 rig which consists of a single 15" speaker.I've found that i'm driving this speaker to hard and the DDT(red LED) is coming on a lot of the time during playing.I have an output for an extension cab which would make the whole unit itself run at just over the 300w rating.At the moment it pushes out 200w. Peavey do a 2x10"(210TVX) or a 4x10"(410TVX) cab setup but my question being what would be the better choice considering the extra 100w output i'll gain.Ok so there will be tone and range differences with the differet cab choices here but is it really worth considering a 4x10 cab just for the sake of an extra 100w?? Will a 2x10 provide the same results?? Thanks. Michael.
