What would you use for an external limiter?
May not matter once the 2nd sub arrives. I was running a tad to hot.
Well, that would be my last resort. For what those JL's cost, their limiter shouldn't be making noise. It should be as graceful as possible. Genelec's and Bag End's low cut first, like if they are running out of excursion they start to low cut at 25Hz, then 30Hz, then 35Hz, and so forth. Then at some point they start to limit the whole signal with a hard knee. At any rate, when I run those too hot, they just don't get any louder...certainly no noises. That's how it should be.
Now, for 200 bucks or so you can get a adjustable knee limiter from dbX or someone....166XL or something, that will work fine.
I'm not trying to wind you up about it, but, I just personally hate having to worry about speakers making funny noises when I watch a movie. Nothing sucks like watching some awesome action scene and wondering when they crash if your subwoofer is going to pop. With a limiter, it should be worry free. You shouldn't be on the limiter all the time, but, if it happens, it shouldn't make a noise.
