Ghostrider: Thanks for the clarification. For some reason, i was thinking that these were quite reactive loads.
As far as 1 ohm speakers go, some of the Acoustats ( and possibly other E-stat's ) hit 1 ohm at very high frequencies. I know that my Ohm's drop well below 2 ohms but do so at low frequencies. Nothing like asking an amp to deliver all it can at frequencies that already need gobs of current...
As far as the Scintilla's dropping down to .6 ohms, good luck : ) If we put 2.83 volts into an 8 ohm speaker, we have about .353 amps flowing through the output stage of the amp. This is equivalent to one watt of power. If we put that same 2.83 volts into that .6 ohm load, we've got almost FIVE amps ( 4.717 ) flowing throw the output stage. This is literally 13+ times the amount of current. Needless to say, MASSIVE heatsinks and / or forced cooling would be pretty much mandatory. This is especially true if you were "standing on the throttle" for any amount of time. Sean

PS... I don't think that the guy that was using the bridged Perreaux 2150's was using them to drive Scintilla's : )
PPS... People with Scintilla's can charge folks money to break in their power cords. If they rig up adapters, they can use power cords as speaker cables and draw as much or more current through them as a refrigerator would : )
