diy crossover for hard hitting 80-100hz for Ultimax
I'm looking to diy my first crossover for a 12" Ultimax. I would like to focus on bring out snappy hard hitting bass. I have no idea where to start. I just finished Upgrading the crossovers on my Hivi's so it seems simple enough. I just don't know how to calculate/research components to get the sound I am looking for. Any advice/links would be appreciated. Thanks

I doubt if this one has a subsonic filter, maybe it does, but it would be a good place to start.
You could take a look at it, figure it out and maybe make one better.
I doubt if you could make one from scratch for less without a pile of spare parts already.

You do not write which dayton model, the 10" is best in a sealed 24L cab, no need for subsonic filter. the air pressure in the cab keeps the excursion constant.
the sound means each time the voice coil bumps on the pole plate and soon the speakers gone.
The 12" has such a high Qts it needs the whole boot as an enclosure, the baffle should be sealed from the boot.

Currently I have Ultimax 12" hooked up to a Dayton SA1000 in a sealed 14x14"x20" mdf enclosure that I built.
My test song is "can a drummer get some" it has a lot of hard hitting quick bass. The JBL will shake my entire house but I can only here the drums like a thud, but dont feel it in my chest.

the enclosure is too small will have a resonant frequency fc=40Hz and a high Q of 0.89, but you should be able to get 114dB with your amp with maximal excursion, which is good.
To diminish the Q factor is not easy, one possibility is to apply damping material very close to the chassis, I used rubber bands to keep all in place.
Never the less from your description it seems the box is leaky.
Easy to test with a low frequency like 20Hz. Listen for hissing sound, good to use a stethoscope to identify the leaks.
It is also good to make an impedance plot, where all this can be verified.
