C-W were also showing a 12-inch(?) driver which they
would plug directly into the 120V power mains outlet in
the hotel room.

There were rumors that C-W cracked some plaster and had
to pay the hotel for repairs.

I believe that there are a number of extant modern
woofers that can survive this treatment for at least a
little while without tricks. 120 volts is the same as
1,800 watts into 8 ohms, which is not an unbelievable
amount of power by modern standards.

On the tricks side, a woofer with a 60.0 Hz resonance
would not absorb *that* much power, given that its
impedance at 60 Hz might be as high as 30 ohms or more,
and only 4 amps (480 watts) or less would need to be
dissipated in the voice coil.

Also, a woofer with a 16 ohm voice could would need to
absorb *only* 900 watts. A mere pittance! ;-)

Mmmm.... Don't try it over here in England.

Yup - 230 volts, 50 Hz.
