The imaging is probably terrible with the speakers located down around one's waste waist.
I bet the ambience is a really dead in there anyway.
I would think true audiophiles would prefer greater dispersion.. like dust in the wind.
I wonder how many are interred with headphones?
Perhaps in-ears would be more appropriate for eternal slumber or at least the open-casket funeral service to assist the deceased drowning out the room chatter.
Imagining future civilizations unearthing such a sarcophagus and drawing conclusions about our current day pharaoh’s conceptions of the afterlife.
