low pass crossover help

[casper17000]

hello, i have a pair of JLx02 2way crossovers and i want to hook one or both of them up to my sub as a low pass filter. however im confused on the markings. it has 3 "TW -" and 1 "TW+" and 1 "W+"and 1 "W-" then "-input"and "+input. what are the tw and w's for? is there a diagram online somwhere for these or can somone tell me how too connect it for low pass(bass only)?

I bet this is a x-over for woofers and tweeters so : TW = tweeter and W = woofer.

Can you play with the frequency on this crossover? It's a passive or active crossover? I'm not sure you can use it for your subwoofer, because the crossover frequency is probably way too high.

That crossover is passive and for a specific set of component drive units. It's next to useless for anything else and certainly of absolutely no use nor even modifyable to be any use, for a sub.

Hi,

I wouldn't say its next to useless for anything else, car crossovers
are notoriously crude, and its probably just as applicable as the
next car c/o for use with a bass mid unit and tweeter.
In can certainly be internally modified to work well.

But as RB says, no use at all in the context of a sub c/o.
