Maybe this is a little off topic, but I know there are some on this forum who can give me an answer.
I have 2 Altec speaker systems. One is 8 ohm the othere is 16 ohm. I was curious as the the effect of using both the 8 and 16 ohm taps on my Mc Intosh MC 240 to drive both sets either individually or Both at the same time. They both have the same bass drivers, 416's, but different compression drivers, 806 vs 399.

What are the effects or hazzards of attempting this?
