Okay, shooting from the hip... I've never heard of anyone having tinnitus at 20 hz,or even 250 hz, It'd be like a bumble bee living inside of your head. But this is where most of the wattage in our amps is used.
I think we all agree that we WANT the extended frequency in our audio systems because there's information above 20k that we don't hear, but there are subharmonics generated below these supersonic frequencies that translate into harmonic information and/or spatial cues in the range that we DO hear.
Rupert Neve, recording console designer extraordinaire has been designing audio recording equipment that is intended to reproduce up to 100k (100,000 kilohertz) and higher since the 1970's.
High frequency sound waves like this are pretty easily attenuated by walls and carpeting so unless the kids are right in the room with you it's pretty hard to imagine them
being harmed by it. I do however wonder about my dog's hearing when she sits beside me during listening sessions...
