Have you looked into bass shakers? They are popular in home theatre enthusiast and driving / flight simulator crowds.

Still niche, but can provide the sensation of heavy bass with near silent sound.

I have a project integrating a wireless shaker system into the Herman Miller embody.

Damn, I completely forgot about those. Any recommendations?

I am still at the design stage, but I am looking at something like:

- AuraSound AST-2B-4 Pro Bass Shaker Tactile Transducer

- Nobsound Mini Bluetooth 5.0 Power Amplifier

- TalentCell Rechargeable 12V 3000mAh Lithium ion Battery Pack

My biggest concerns are custom mounting of the transducer(s). Not sure where will give the best effect without damaging the chair.

My goal is for it to be wireless, splitting bluetooth audio into channels for AirPods Max and this receiver.

Concern there is I don't know what the latency will be like, or if I'll need to introduce delay into say the headphones channel. I have a few of the Rogue Amoeba tools, including Loopback that I'm planning to bring into the mix if necessary. Another idea is to separate the amp and BT receiver, getting something more professional like the Fiio BTR5.

The MVP should probably just be a wired connection to the chair, so maybe that can prove the mounting and potential first.

That's where I am at. But I have the same concerns as you, I don't want loud I have great headphones, just more immersion and more bass feel.
