Hey Audiophiles: Can you solve this problem?
I am a freakin' genius...
A friend of mine went nuts and setup a beautiful home theatre. Looks amazing, sounds great. Watched a movie, oooh'ed and aaah'ed at the earth-shattering kabooms, etc.
EXCEPT: 1 of his 2 sub woofers had this bumpbumpbumpbump sound (A thump sound that played about 5-6 times per second). It was too low to hear when music or movies were playing, but it was definitely there and could be heard throughout the room when quiet.
He has fiber-optic Internet, fibre-optic audio from TV to processor, HDMI 2.1, all the latest and greatest. Internet connected everything.
His Sub Woofers are wired and self-powered.
Techs went to his house after the installation and could not find the problem.
I figured it out in 5 minutes, hearing nothing more than that sound, and with no more information than I provided above.
Can you guess what the problem was?
