I feel your pain. I live in pristine wilderness and until 15 years ago had no year round neighbors. The absolute dumbest rock in a box of rocks redneck (maybe my guy and yours related) somehow managed to get into the crappiest little upstream fish shack and shortly after moved a 80's vintage Peavey bar system into his garage with a sub that is just a one note flaaaaab. Now I despise this guy more than most humans because of all the loud toys - ATV, side-by-side, snowmobile, monster truck - year round annoyance. And he knows I despise him.
One day I showed up with my measurement gear and offered to tune his system. He was suspicious but the sight of the gear intrigued him and after I went through some sweeps and white noise was able to tame the worst of his one note sub to at least make it musical with his 32 band EQ.
I still absolutely despise the guy but at least now when he turns it up to "11" I get music instead of blub, blub, blub....
