Ambient 4 , On Land

To make it work the two -VE terminals of the two amps need to be connected 
as 
well.
(for a stereo amp this is usually the case, but certain stereo amps may be 
damaged
by this)
Impedance? probably safer to use an impedance at least twice that of your 
main speaker,
the higher the impedance the less volume you'll get from the extra speaker.

The system is assymetric  in that the extra spkr is in phase with only one 
of 
the main speakers( this situation can be helped with another spkr in 
series 
and out of phase with the additional one).

I used an ancient spkr with a volume control  along with my hi-fi  for a 
while, nice effect.
