MC2 E45 amp ability to power 2 ohm circuit

Yesterday I also made a post in the scoop forum for driver recommendations where we're deciding to go for 2x 8ohm or 2x 4ohm drivers for our hog scoops (so resistance of circuit becomes 2 or 4 ohm respectively). The amp that we will use is the MC2 E45, which according to the spec sheet should be able to power a 2ohm circuit with a max output power of 4200W. Now this seems more appealing than a 4ohm circuit which has a max power output of 2500W. 

Many times I read that 2 ohm is not good for the amp etc. but can anyone explain why this is? If the spec sheet says the amp supports 2 ohm circuits, then what would hold us back from utilising that? I've been reading up on it but I can't really find a definitive explanation. We've been discussing this topic with the people of our soundsystem but we don't really know what to do (we don't have a lot of experience). If anyone could shine a light on this that would be really helpful!

Cheers

Void Inf8 v2 will do it on a decent supply (seen peaks of 40a on the front doing what you're asking, "2ohm" load per side), but also probably pop fuses internally, again seen it happen.

And yes, the E45 could handle 2 Ohm loads (with the test conditions specified in the manual), however, I would not run it that way for different reasons like durability etc. Heavy 2 Ohm load will require more current which then results in more heat.  PS: if you're after a transformer amp, I have a Infinite 7v2 for sale. Not a 8v2 but it can do for some occasions.

Mixed genres basically, mostly dub/dnb/techno I'd say.

Could you explain what a transformer could mean for us in this scenario?

That makes sense

And as hinted above, any gain you think you are getting is destroyed by power compression.  Stick to 8 ohm drivers - and you could then, at some point, add another cab per side without over-stressing the amp - which is far better.

Yeah that sounds like a solid plan for the future. But then for future expansion we could also have gone for 2x 4Ohm drivers per channel instead of 2x 8 ohm drivers. But reading all the other comments I guess we should waive that idea. It just sounded attractive as the output power is higher but I'm starting to understand that this is just bad for the amp.

I'm afraid that's a bit out of our budget haha. I guess moral of the story is that we should not go for a 2ohm nominal circuit. Did your void amps survive that current? 

Yes we've got all cabs already. Only need to put drivers in our hogs, the rest is all done. Never heard/read about paraflex cabinets yet, got some links to read up about?
