Aren't the Holosonic based on the ultrasonic transducers that beat use frequencies? Gives a super tight beam.
There has been military use of the technology for a few years, some of it is coming onto the commercial market.

Put system in a different room or use wireless headphones. You might like the headphones, as you can each (assuming two of you?) adjust the volume and move around the house. Neighbors suck...

If you can glue 2 layers of sheet rook on that wall it will reduce the sound for the neighbors by several db. That's the first thing I would do if possible. Sheet rock is cheap. You can do it yourself if you get the landlord's permission or if it's your place no permission is needed.
Then, what about some medium sized OB speakers combined with some bass shakers on the couch instead of a subwoofer. The OB's don't load the room much so should cause less wall vibration. You can build a platform to sit the couch on and fill it full of sand to damp vibrations so most vibration is transmitted into the couch. You probably need a good hardwood couch for this.
You can also set up a nearfield listening setup where you have all the speakers in the surround setup up close to the near field so you don't need as much volume. Kind of like a 6x8 foot pair of headphones.
The other alternative is some good dynamic headphones with lots of bass like Beyerdynamic dt 770. You can get multi output headphone amps from the Pro audio recording dealers so you can hook up several pair if you need to hook up more than 2 pair. A Y splitter is good for 2 pair if you have a decent AV receiver.
My neighbours aren't easily bothered. For late night HT/music, put in a variable high pass filter and get some heavy curtains for the windows. When watching movies, put in in compressed mode on the receiver.
I have kind of similar problem, but just in stereo. I was thinking about a "stereo chair" arrangement - speakers relatively close (20-50 cm) to ears facing each other with my head inbetween. Something like giant headphones previously mentioned.
There are two things - most probably, only coaxial and full range speakers of small size could be used.
Second, if I wanted to use the dipole - how is the frequency response in the lows different from far field listening - if it makes sense to use dipoles in this setup (maybe just for lowering the noise around.

I have a pair of Phantom Acoustic Shadow Prototypes that sit in room corners with drivers tucked into the corner at both the floor and at the ceiling. These speakers reduce low frequency standing waves in the corners and in room by about 6 dB through destructive interference.
Ok, 6dB at the corners is not a huge reduction, but it's the difference in our house between The Boy being able to sleep upstairs durning a movie played downstairs.... and not.
Ask Nelson over at the Pass Site about the Shadows.

Your problem is that you live in a reverberant space. Once you get the distance between the speakers and wall to equal their critical distance at which direct and reverberant SPL equal additional increases aren't going to drop the SPL reaching the party wall more than 3dB below what you hear at your listening system unless you're within the critical distance from the speakers. This happens at about 3'.
Reduced listening volumes will help. Dynamic compression aka "midnight mode" will keep the details more audible at modest listening levels.
Turning off the sub-woofer will help. Sound transmission is worse at low frquencies.
Mechanical low-pass filters between sub (especially)/floor and speakers/floor will help. A flat piece of wood on top of thick carpet is a place to start. Wood on sand would work. Commercial products like the Sub Dude are available. The idea is to stop structure borne transmissions.
Hi,
best cheap way to decouple the sub from the floor is employ 3 ( or four) steel spring instead the spikes. Choice a "soft" type to obtain a FR very low,
out of the audioband, 3-5 Hz is easy target. ( push the sub and check
visually the oscillation) . Probabily you will hear better sound quality also
😀
Cheers, Paolo

Hello, I would love to - but any headphones I wear start feeling unomfortable after 30-60 minutes and painful after two hours. I have tried more brands and it is always the same. The only headphones that I would probably not mind are AKG K1000, which are not manufactured any more.
