But as Duran mentioned, not really a ported enclosure subwoofer.
I used to have four of the 88120DVC (12" version of that model).
Defeated I concede and move closer.
I may find comfort here. I may find peace within the emptiness.

I've also got (3) 88120 dvc titanium's that I've in the same box driven by a jl 1000/1 and it sounded the same as the aluminum just louder.
I have (2) 8808 dvc as well I was running them in a .75- 1 cf (don't remember for sure) 32 hertz tuned driven by a jl 500/1
Give it a shot both ways you might be surprised.
I used a pencil and paper to find "optimum" volume and ran with it.

I've always been a fan of smaller boxes, but damn the port length is long.
I think they're great sounding subs.
here's the T/S parameters if you don't have them already.
Fs.> 26 hz.
Vas.> 2.1 > typo in the manual, it says f^2, not cf^3.
Sd.> .0357 m^2
sealed enclosure (recommended) as per the eclipse manual.
1.0 cf> Q .81> f3 40 hz.> Fc 45 hz.> ripple .27 db.
.75 cf > Q. .91> F3 42 hz. > Fc 51 hz. >ripple .74 db.
.5 cf > Q 1.0 > F3 46 hz. >Fc 60 hz. >ripple 1.7 db.
I called eclipse and asked for a recommended ported box size( a long time ago ), they told me it wouldn't sound right and they don't recommend it.
I tried it anyway (had to see for myself) and it sounded the same but with more output.
I believe it has linear spiders not progressive spiders.
