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.
