Sub is 80-90% perfect. The fix? STUFFED it with PolyFill.
I think I mentioned somewhere that the shop in town told me that he was at a training and all subs benefit from polyfill. Use it and don't be bashfull.
He was right.
It sounds much better. Not exactly perfect, but very good. I still may build another box, OR get a different driver. Haven't decided yet.
As per the polarity test... I couldn't figure out a way to test from the HU. I downloaded an app from JL Audio which can test polarity. I tested all four doors and they were wired correctly.
Then I ran set up yet again, this time turning up the Max volume to the "m". Then I used the custom HU mode, set crossovers, zero'd out timing numbers, and saved.
Everything sounds so much better! WOW... not kidding. It flipping sounds GREAT! (except for a low hiss on talk radio stations.)

Glad you got it sounding better! I have an undersized box and no poly I want to add about a pound.

Let me try to define "STUFF". I didn't pack it too tight, but I did fill every void around the driver with poly fill. Then to test, I'd use four fingers spread wide. If I was able to wiggle my fingers in, without moving the clump of fill away, it was good. If not, I'd add more. Not sure if that helps.
