I've tried searching pretty extensively, since I think I had read something about this before, but no luck finding my answer, so apologies if it was obviously found by anybody else. The gear I am working with currently consists of a Fender 800 Pro head into an SWR Goliath Senior. I've recently ordered an SWR Big Ben to help the Senior out on the low end (it starts to drop off pretty early). The 800 Pro provides 800 watts into a 4 ohm load, and 1200 watts into a 2 ohm load. 1) Since the Goliath Senior is a 4 ohm cabinet, and the Big Ben is an 8 ohm cabinet, am I correct in saying that they'll put a 2.67 ohm load on the 800 Pro? 2) Would the Big Ben get half the power from the amp that the Goliath Senior does? If so, will that make their respective volumes too different? 3) If their respective volumes ARE likely to be too different, what possible solutions, short of buying a seperate power amp for one (or both) of the cabs, could there be to this problem? Thanks in advance for your help.
