Using the system, people can compile their own personal playlists before they die and the music will be streamed into their coffin.
Even when they have gone, relatives can update the songs for their dearly departed via Spotify and a ‘Catatomb app’ using a touch screen built into the gravestone.
The music is piped into the casket via two-way front speakers, 4 inch mid-bass drivers, ‘divine’ tweeters and ‘a hell-of-an-8-inch subwoofer’.
They are powered and fine-tuned to the coffin’s unique interior acoustic space which is fitted with an external cooling system so they don’t overheat.
“Just because you are dead, you should not be deprived of the life-enhancing power of music. Some people believe that a beautiful melody can reach beyond our senses. Now you can expect nothing less than godlike comfort and heavenly sound from the catacoffin,” inventor Fredrik Hjelmquist of Stockholm, Sweden, said.
“This is designed to allow customers to embrace their passion for music, in this life and the next. Hi-fi is my biggest passion in life, and I will take it to the grave.”
“People in Sweden are so stuck up about death - I wanted to give them something to laugh about. I was very afraid of death and I wanted to lighten it up a bit,” he said.
