Ohm related cabinet question

[80's_Metal]

I am no genius in this dept. So I figured I would ask you guys. before I set something on fire and ruin George Lynch's favorite amp!

(ya that's half tongue in cheek, and half "hell yeah GL touched my amp!"



I have a Randall RH200 G2 (200w) Solid State head, her big butt looks like this:

Currently she is sitting atop a Randall 4x12 with eminence (150w) 8-Ohm speakers.

Tomorrow the Fedex truck will be delivering a wonderful new-to-me Marshall 1960a with some mix-matched vintage 30's and original 75w ... 16-Ohm speakers onboard.


Question: :scratchch
Can I run them together like a full stack without wrecking my amp?
Or should I run them one at a time?

I know the cabs are different animals altogether, and they may not even sound good together like that, just want to be safe.

Thanks again guys!

Re: Ohm related cabinet question

If one cab is 8ohms and the other 16 ohms that makes 5.33 ohms if both are connected in parallel. 16x8/16+8 Your amp seems rated at 4 ohms minimum so 5.33 is just fine. However the 8 ohm cab will get more juice than the 16 ohm cab. This might be a very noticeable difference volume wise or it might not depending on the efficiency of the speakers in each cab along with their frequency response especially in the 500-2000 khz range.
