I have mine at 50Hz. Is that too low for my k2ps??

Yes.

But the saving grace is, the Focal crossover probably protects the woofer and has your "real" HPF (signal to the midrange) somewhere around 100hz. No reason to go under 80hz if you actually are full active, it wont help your response @50hz or whatever you think you're going for.

I set mine at 220hz when I ran 4way with 8" mids also, and set at 80hz in the head unit but also run passive with my CDT 560 xover.

Buy a better 4chan amp, your components will thank you. JL amps are not "going big" IMO.

if you lower try using a steeper slope such as 24db

65-80 depending on which set up I am running.

Ab out 70 HZ seems to be my 'sweet spot'. Any higher than that and I don't get a firm up front 'kick' I like to cap off my deep bass tones. Any lower and I get a frequency response peak in the 50-80 HZ region that causes really, sloppy booming resonance if I play anything that has alot going on in this range, not to mention I loose undistorted volume.

"Going big" is a subjective term. :D

50hz is pushing it. Most 6.5 comps and smaller are designed to be HPed from 65hz and up. 80hz being the most common with a 24db slope for better clarity at high levels

80 at 12db on my id's.

63 at 24db on the sub.

Since I have no sub right now, my dayton rs180's aren't HPed at all...and they still don't bottom out unless I'm really pushing it.

A lot of Morel's mids will go down to 40hz with a properly treated door.
