If you were not in Michigan ... I would go to this event. I could show everyone a few tweaks that actually work and have a panel of AVS Forum members to back up my claims.
Here is what I do...and if you value defined, articulate, note accurate bass ... as I do ... the results are proven and dramatic.
First thing I would do in your setup is turn the Subwoofers sideways, 90 degrees away from your ear. This way you are not getting the direct radiated sound from the sub that will cause your main channels to sound muddy, less articulate, and less defined.
Properly done, this will improve detail, imaging, accuracy, and musicality.
First, calibrate your system using a tones and an SPL. This is a good rough in, but not the final end all be all tweaked setup ... at least not in my opinion.
Then, take an accurate laser tape measure or an old fashioned tape measure...and move the center of the sub to within 1" of your main speakers as measured from your listening position.
It does not matter where the sub ends up. As you can see in my Office Stereo System pictured below, the sub is quite a distance from the wall. This is where it needed to be to meet the spec I outlined above. If I move it even 1" from where it is, I immediately lose definition, detail, imaging, and clarity .... across the entire spectrum of sound.
Proper subwoofer setup, adjustment, and position impact overall sound quality on a level that is dramatic and demonstrable to anyone in the room. I have been able to show the difference to anyone ... and once I tell them specifically what to listen for ... they can detect even the most subtle changes from that point forward.
After you are done turning your subs sideways and measuring, put on some reference STEREO material, preferably a well recorded jazz album with very defined acoustic bass. I prefer to use Mapleshade Audio recordings. Just call Pierre and tell him you want some "good plucked bass" ... he will laugh and then set you up with a reference album or two. Believe me, you will rarely ever hear anything that sounds like Pierre's recordings.
Then, while listening, turn the LFE / Sub Level down until you can hear the bass player's fingers clearly on the string....or as close to it as you can get with whatever you use for speakers. Less sub is better than more, so it is always better defaulting to less Sub Level than too much.
FYI - I strictly using Gallo Strada Reference or Diva Ti Speakers in my systems. Their ability to deliver accurate, detailed, clean, well imaged, articulate, musical, note accurate sound is nothing short of amazing.
Then, while listening, move the sub a few inches in each direction until you find the point where it "couples" with the room. You will know right away because the plucked bass will become one with the room. You will no longer be able to define its location as "Coming from the Sub." Instead, the bass will become part of the soundstage ... tighter, better defined, and with better rhythm, pace, musicality and synchronicity. In addition, you will notice your main speakers open up dramatically in the same way.
People may argue that they do not listen to music on their home theater systems like I do. However, it doe snot a matter. Poor sound is poor sound...EVERYTHING benefits from setting your system up the right way ... and it just so happens that music is the easiest and best thing to use for tweaking your system.
Of course, some people like rumbling, poorly defined, muddy bass...they think that is cool. This is where the opinions come in to play. If they like that sound, that is their preference, so they should stick with it. Personally, I do not like that sound. I want to hear every detail there is to hear ... I do not want anything buried in the mix.
This is only one tweak...which is really Pierre's tweak to be honest. I have known Pierre for years and he has never been wrong once about system improvements and recommendations. Not once in over a decade that I have know him.
I also have some other tweaks as well...and ALL are demonstrable and easily proven ... but they go against conventional beliefs.
Unfortunately, most people would rather debate about something they have never even tried rather than trying it first and seeing if it actually makes a difference...so I rarely step out and make these recommendations.
Figure I would try and see how many flamethrowers come out and get pointed at me ...

For the subwoofer shootout, I have 3 un-used subwoofer feeds, one on LH side of front wall, and 2 on LH wall front and rear portion.
Prior I'll put my family room subwoofer in 2nd row and 1st row actual seat and do a subwoofer "crawl" listening to optimual "other" position for sub's for the shoot out. They also have power by each as well.
