Impressive, though... mine get warm with 250-300 watts on them.
Doesn't matter, though... 6dB is still 4x power from amp/to subs. If you're running 16 of them @ 200 watts each for a total of 3200 watts, then one day you want to boost 20hz by 6dB... all of a sudden you are requiring 12,800 watts from your amps and are giving each sub 800 watts @ 20hz.
I just don't want noobs(and other people who don't know) reading those "boost it" posts and thinking it's as simple as "boosting the hell out of it" down low and all will be okay.
Best scenario, if you're putting them into small boxes, is to probably run a ton of them and CUT the high frequencies to make it however flat you want it.
Eh, I think that's a pretty simplistic example that just doesn't play out in the real world the way we use them. Let me know how listening to 3200 watts in the non-boosted territory on 16 JBL's works out for you. I think you don't realize how efficient these things are, especially at those frequencies. It's going to be so far beyond anything reasonable that it just doesn't matter. Sealed boxes always have more output potential as freq increases, at least up to the thermal limits. If you have 16+ of these you're not going to find the thermal limits above 50hz unless you've really hosed up your room and/or phase or you're using them to put on a high-school dance in a gymnasium.
Boost low freq's. Cut the high freq's. Linkwitz transform them. Do a combination of all the above. Doesn't really matter as you're doing to adjust level the same for the same
output across the same frequencies. You're not exceeding amplifier or thermal limits either way.... IF YOU HAVE ENOUGH OF THEM. Even my computer system has 4 and I was thinking about raising that number (why not?).
FWIW I tend to land somewhere around 150-250 watts per for most of the applications, and that's max
. I listen loud, with a filthy room curve and sometimes use a subharmonic synth that adds up to 15 dB from 15-35hz, and even then they're so efficient I have to work to clip the crowns, definitely far, far past neighbors calling police territory, into visible wall deflection, visible waves in the leather couch, things falling off shelves in adjacent rooms. I once measured 110 dB outside my front door. I don't do that often, mind you, but sometimes everyone needs to listen to a little AC/DC.
So yes, as previously stated, get a bunch of them, eq the snot out of them with boost, cuts, boost and cuts, whatever, and have fun. It's a modest driver with good characteristics that becomes amazing when used in large numbers.
