Lebercr living in townhouse condo is s real problem when having loud playback volume. Walls usually don’t offer much in the way of sound containment between units.
Me personally I would speak to the units closest to your rooms boundaries above, below and beside.
If you have a system already that you could play something you like at the volume you most likely will listen at considering peaks for explosions or deep bass in music.
Have someone in your unit resume playback while you and your neighbours listen to the sound pollution into their units would be the smartest and most considerate!
Be sure to set max volume in your AVR to the limit of the neighbour that whined the most or has the least tolerance to your toy!
My system in 2004 without a sub was so loud during playback that my neighbours could not hear their TVs when I played it back -20 from max volume. The LFE was going to my mains and shook their living room.
Sucks to have great speakers and other gear which isn’t cheap and put a muzzle on it!
Fully detached home all the way!
