Man you gotta be excited for the dedicated room! If it were me I would think extra drywall, not sure how much. I've also heard of green glue and whisper clips to decouple and further isolate from vibration.

Three layers of 5/8 drywall with Green Glue dampening between layers. mount the walls, ceiling and soffits hiding those ducts using a clip and channel isolation method. Address HVAC isolation and all holes in the drywall bunker for electrical etc with appropriate strategies. click the curve frenzy theater in my signature for a similarly insane audio adventure.

^ Me too.
Luke, I'm not surprised at the recommendation for 3 layers. My room doesn't have anywhere close to the fire power you have, and I already fear for the drywall on the back wall. As you know it's crazy how much it can flex and move with the bass - I'm somewhat surprised that I don't have any cracking issues yet.
Good luck, I'll be following this thread.

Looks like your ceiling height is a little over 7ft... correct?... Instead of 9ft or so... 3 5/8 layers on the ceiling may be a little low if your build a riser...

The ceilings are just under 8ft...and then there's the duct work on the right side. I'm not sure what i'm going to do with the ceiling since I don't want to lose even more height.

If you are wanting to contain sound...there is no getting around loosing a bit more height... What would be the point of beefing up your basement walls, but not the ceiling...
My theater is directly below my den. Family hates life when I have sessions without them while they are hanging out in the den.

Have you considered staggered studs? May help if you have the room.
