Hi,

I have an old pair of JL12W1-8's that were intended for car audio 14 years ago. I've modeled them a bit in WinISD and am considering whether or not it's worth building a box for them or not.

Any thoughts?

What application? HT, music, or both?

70% ht 30% music. I currently have an ed a3-250 as well. Just looking for more output. They could transition to subs for the garage down the line.

For a sub with a limited Xmax of 8 mm it would take a fair sized box to get any low end. Shown is each in 12 cu.ft or 8 cu.ft. 45 watts would reach Xmax. A 150 watt plate amp with a high pass filter at 18 hz would power them both if wired for a 4 ohm load.

They may be suitable for an MBM project. I'm using a pair of JL8w6s for my MBMs.

That's a massive box for these boys so they maybe are better suited for sealed garage music subs (subs for the garage).

The MBM idea is interesting.

WOW, 8mm of xmax. There are 6.5's with more xmax than that. :rofl: :hide:

Yeah but JL Audio makes very good musical subs. There w7s would be a really nice sub to have though.

Amen to that!! The W7 is a nice sub, pricey but NICE. :T

I regards to his W1's I do not believe they would make a good HT sub unless he uses a low wattage amp and a subsonic filter. Even thin he is going to get limited tactile emotion from a W1.

Thanks guys. If I box them up it'll be simple sealed for the garage stereo.

They were good money back then for my car audio plans but I guess HT is a different game.

The orange curve modeled by Mike looks good to me. Not very loud but there are 2 of them...

 

[mdrake]

The orange line looks nice but the spl is low and the other problem was when I modeled them they exceeded xmas at 30hhz with only 100 watts which to me does not seem like a good candidate for an HT sub. It is really amazing how far driver technology has come in the past 10years!!!!! :hide:

Well, I am saying it is still better than nothing, 2 of them in a small room will not hit RL for sure, but will still be something.

 

[dvand]

yeah I would have entertained it if the box wasn't so big. That's pretty large without much performance so I think I'd be way better off investing in a good sub to place in that box.

Ya, they would be better than nothing and probably better than a cheap B&M subwoofer.
Another option would be to horn load them then the Xmax would not present near as much of a problem but horns are a special breed.

I can tell you the Quality and Quantity of bass from my Mal-X is worth every penny I spent!!!!!!
