First up, apologies for not being able to find a thread that covered this subject even though I'm sure it has been discussed. Here's the story: I have a Focus SA that delivers 800w @ 4 ohms and 1000w @ 2 ohms through a single path. I am interested in what happens with the following two cabinets - a 4ohm Schroeder 1212 (rated at 1000w) and an 8ohm Epifani T210 (rated at 500w). If I ran it all together, what do I need to be aware of in terms of not overpowering the Epifani? Is there any way i can approximately tell how much power is going to each cabinets? And (as much out of interest as anything) is the power output of a power amp linear in the sense that when I turn it to halfway is it roughly putting out half rated power output? Cheers - and happy holidays to all.
