Hey Taln, can you run a graph for the IDQ 12v3 D4? I'd really like to know what a pair of those in 1 cube each sealed with 750 Watts a piece would do...

here's the frequency response, and cone displacement graphs... you'll well within the X-max, so distortion should be low. QTC of a 1cuft box per sub is .691, fairly low for a sealed setup.

Red line = 2cuft sealed (1cuft each) looks like usuable range down to 30hz.
Blue line = 10cuft sealed (to simulate what an IB setup might look like)
The IB can safely play about 5hz lower than the Sealed can, I don't know what the x-mech is on that sub, so its possible it could safely play much lower, but with added distortion.

Hmm...I'm wondering if...

Those L8s are usable down to 40 Hz...

...Instead of hijacking this thread, I'll PM you Taln...

Any one out there know what software was used to get those graphs? or a similar one?

jbl speakershop as one of the examples

WinISD online and WinISD the installable application are both good freeware apps to use.

That is my subwoofer an IDQ 12v3 D4 in a sealed box of 1 cu feet. and I can only say good things.
