Does You Subwoofer Settings ??

Many years ago, I bought my first Harley. As you guessed, an 883. Then a 1200 Sportster. Then a Deuce. I had custom tins and wheels on it. It was sweet, but not comfortable on long rides. Then a Road King. And finally, a Road King Custom. It was a sweet bike and I could ride it all day. But, I lived in Nebraska and the riding wasn’t great. All my biker friends were busy with kids and so was I, so I sold it.

No bikes now, but I have a 52 Chevy pickup and a 62 Chevy pickup.

My Sub is approx 24 inches off wall and corner

This is very likely not the best spot for the sub and probably a big part of your issue.  As I mentioned earlier, do the sub crawl method to find the spot(s) where it’ll likely sound much better and very possibly mitigate the problem. 

I'm also 73 and i think I've become a bass junkie, or should I say truly full range music listening addiction I have tower speakers with built-in powered subs along with two SVS Ultra 13 subs with the upgraded plate amps  I listen to everything from Frank Sinatra to Odesza  Typically I have my subs crossed over at 38 hz and adjust the gain to eliminate any boomyness  Almost all music sounds coherent and not overbearing, no matter the music  Hey my brother had a Harley Sportster and would let me ride it once in a while I reciprocated by letting him drive (hard decision) my 1972 BMW 2002ti  

@jrwaudio I greatly appreciate the fact that you’re rockin’ two SVS Ultras to Odesza at 73. That’s both next level and refreshing to hear!

@toro3  Next Level until.my neighbours are on my porch with torches

And I've discovered Daft Punk!!  Seriously though. I love how subs can energize a room when music like, London Grammar song Hey Now is played
