Crossover

What is a good crossover for cutting out about 25 hz and below. about 30 dollars or less. I can get one for that cheap. Just wondering if anyone else could come up with one.

many decent crossovers have built-in subsonics filters

Have any that you know of off the top of your head? Cause I can get a shop to install it and they will add one for about 20 dollars

you just want a subsonic filter set at 25Hz?
Well these are the simplest, I have a set and they work nicely.

I need 25 hz, not 20 though, I am going to use this for my ed15 in a ported box

All Audio control products with the PFM feature do. I am sure there are other companies as well

Well I just decided to stop trying to be thrifty and buy a tsunami class D instead of a profile.

good choice :)
