Yeah I'm pretty sure that insulating against that is going to be a primary
concern of any decent speaker manufacturer. Also, wouldn't the transformer and
amplification process (going through to DC as well as through capacitor banks)
pretty much mute most of that even without specific engineering?
One of the nice things about 60Hz, though, is that it's pretty close to the
specific frequencies used for acoustic weapons, due to the effect that it has
on the CNS of humans (not sure about other animals). It can causing headache,
nausea, disorientation, and all kinds of other shit when you get enough power
behind it. So, basically, if you plug a sub that can handle it into the wall
(probably with a little amperage limiting), you've got a speaker that'll keep a
crowd of people at bay. ;)
Can't remember for sure, and I just woke up so I'm not feeling like googling,
but I think the weaponry I'm thinking of is the 'LRAD' apparatus. Okay, I
actually googled it. That's the one. Though it's touted as being at 2.5kHz.
So maybe I need to shut the hell up. I know that I've heard 60Hz being touted
as having significant bogus effects on humans, though. I'm gonna have to
research this more when I don't have wage slavery awaiting me, as well, it
appears.
