What 12 or 15 inch sub should i get for a sealed box?

the bl curve only represents the windings in the gap over stroke. it doesn't account for power compression. one reason JL uses such a soft spider. so you don't get any electrical parameter shifts with rated Xmas and power. it's a great sealed box woofer but that's it..the sundown x or z4 despite they don't recommend the sealed will do great in 1.5 sealed for the 12.

No **** sherlock, although I would clarify that the gap is the "magnetic" gap since something like xbl^2 extends the uniform(ish) magnetic field a bit. How does a w7 suffer from more power compression than other woofers, is their cooling that bad!?//content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif A soft spider isn't a bad thing. //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif TC sounds drivers sounded great using soft spiders and to this day are considered very solid performers. Although the current offerings seem to be riddled with QC problems, but US made TC //content.invisioncic.com/y282845/emoticons/yumyum.gif.0556df42231b304b9c995aefd13928a8.gif Not everyone wants to throw several kilowatts to get a sub moving.

I frankly don't see how you can say the w7 is a flawed driver just because the design decision that went into it don't line up with your idea of what a woofer should be.

OP Are you stuck on buying new?

there is a lot that goes into a jl...... always has been. tech you wouldn't even think of, but makes a difference....... but it does max out where the aftermarket and other brand subs can far exceede....... in it's range, the jl is a great, and awesome clean sub.... but if you waqnt more... jl is not it, at all....... don't even bother with the amps. i tell you those are about the most finiky peices of crap i've ever had to work on... when they work, they work great..... awesome design, but when they don't......, i would be just as inclined to work on a gen1 prius.... there's a reason i never buy blown jl amps.

your obvilously distribed by me, stop being all emotional. i never knocked te w7. i said it was a great design and it is. for the money though they ahave a few wooofers i consider over them. i never siad power compression was low.you mentioned the BL so i mentioned they used a softer spider to have a more linear curve than typicall woofers.

I personally like the ID max woofers. i hear they got bought out but i dont think the design changed.

OP Are you stuck on buying new?

i never said is suffers. i said they use a softer suspension to decrease any power compresion in the spicific alignment(sealed)XBL is fine and dandy but it too has its own set of cons.
