Any sub will go lower in a bigger box. U can make simulations and play with the volume until u get the QTC u want. Weird what u've seen with your RTA. For me it was flat until 20Hz and when i applied a HPF at 16Hz i felt a very small diference. I don't know what to say. The 12W7 had much more authority down low but if the W6 is flat until 20Hz how low can W7 go and still be felt by the human ear ? I forgot to measure the W7 too

Hmm, Amator, after what you said, I've measured the box and it seems the boys made it bigger than Jl recommended. It seems it has 1cuft instead of 0.625 (recommended) and i guess that's why it stays flat until 20Hz. What's interesting, is that it doesn't loose precision also compared with the midbass and blends very well !

It looks like i shld redo till 1 cu feet then Though It blends totally with the midbass now and appears totally upfront. There is however NO low end authority or 'bloom"

Right now, my initial impressions after a month of ownership is that amator is right...

I believe my box is around .7 cubic feet....hard to measure since it's fiberglass behind a wrapped quarter panel in the back of the car.

The only thing I can do is stuff with polyfill....

Im also gonna stuff mine with polyfill, last resort will be slightly bigger to 1 Cu foot.
I tried to play a bit of bass boost and Q ard 20-25hz using my Jl 500/1 but havent concluded whether its natural sounding enough.

Hmm, don't know if a boost at 20Hz won't stress that 10" driver too much. I don't think a boost will be able to replace the smaller cone area of a 12 or 15" driver. I did play with the boost on someone else's 10" driver and i felt the driver was stressed and unnatural sounding !

None of these problems are present in ANY sub from Image Dynamics. Is it worth messing around with subs that don't have bottom end? If they don't all they are is a midbass driver.

i own a 10w6v2 as well, in the box size recommended by JL Audio <0.7cuft3. i feel there's not much kick to it (compared to, say a 12" XLS) and its very subtle and blends very well with the mids.

what can be done?

It's interesting, just a few posts above I'm knocking it for the same reason you are...

Now, I feel like going low enough isn't really the priority anymore but midbass integration. I feel the sub could some some EQing in the lower octaves to smoothen out the sound when I really crank them.

As for low end response, increasing amplifier power and/or increasing enclosure size would be my best bet...I've done the former and it's helped a lot. You could try polyfill if you can't rebuild your enclosure.

In an ideal world, multiple subs in big enclosures would solve all of the problems we run into.

IMO JL tends to be too conservative in their recommended volumes, experiment if you can. just my $.02

Jumping from 0.7cuft to 1cuft would help you go lower and blend it with your midbass even better !

im very interested in that IDMAX sub. problem is my fiberglass enclosure would have to be modificated by adding a 1/2 inch ring to it..changing the .8 box to a bigger box. The JL wouldnt present that problem, but im very interested in trying since the reviews since to be so good on them.

well.. 2 years plus down the road, i blew my 10w6v2 today while i was playing music real loud trying to stay awake. really, it didn't felt it was hitting hard down low

anyway.. should i get the 12w7 now? the amp is a JL Audio 500/1..I don't intend to change amps. but it seems the 12w7 is power hungry..

the 10w6v2 was fine, it just didn't hit hard enough.. it blended well, was fast..mids are G18RNX + LPG 25nfa

I would choose a more efficient subwoofer since you will use "only" 500rms:
AE Speakers --- Superb Quality, Unforgettable Performance, Definitely.

In the right box, they'll hit lows, hit hard and blend with your mids better than a lot of subs out there.

Get the biggest sub you can (taking into account the enclosure size)

Kelvin

PS: they can custom subs to have a 4ohm voice coil.

The w7 would be a fine upgrade. Contrary to popular belief, the w7 on 500 watts will be plenty.
