+1. Your room is almost 3000cuft. I think ported is the way to go too. And your instincts are correct. Even if you had 50 of those drivers, it wouldn't change the extension. Only the output. If anything you might be able to go down to 25ish(I have not modeled these), but that would probably be it. JL does make some of the best drivers around, but they won't defy physics.

Agreed. I know if I want crazy low extension there's no way around it: I need a large woofer with a lower fs and more excursion. I like how musical 10's can be though. Ideally I want a box design that's still very musical, but is usable for home theater use. I know it's a compromise, but I already own the subs and I think I'll be happy as long as I have reasonable expectations.


Can anybody comment on my question about parametric eq's? Am I on the right track or completely off the rails?

27 hz tuning for those sub,s is way to high
I build a 12W3V2 tuned 16 hz, i done this before
4 of these can do much beter .

I read someone thinks i,am wrong.
So be my guest and build them wrong (27 hz tuning)
To bad for these very good sub,s they can do beter.
I don't know how you did it man. I modelled 3cuft at 16 to 20 hz, the cone excursion goes crazy and it looses spl. How's it possible, tuning the box so far below the fs unloads the cone and all hell breaks loose....

It's a 10" driver with 15mm xmax and an fs of 28 hz. Having a dust cap that says JL on it doesn't fix this. It's not going super low.
You have 4.......
If you think i am wrong,i wont say anything

Re: JL Audio 10w6V2 enclosure design

I modelled another box based on some vented suggestions.

The red plot is 3cuft tuned to 27Hz. Highpass Butterworth, 4th order @ 23Hz
I also added on a couple parametric EQ's:
-27Hz, Q=6, Gain = 3db
-38Hz, Q=6, Gain = -0.3db

I've never played with parametric EQ's. Is this a bad idea? It extended the low frequencies and controlled the cone excursion.

Lol, I'm aware. As I pointed out in my first post, I have expectations but I know what a 10" sub is capable of.
