What's with all these new SIXohm Stereo Speakers coming out?!

Trevor:
"SOA"?
== Safe Operating/Operation Area == combinations of frequency, voltage and
current that will not blow the device (transistor) up.
Remember again the issue of phase angle between output voltage and output
current in a reactive load, something that leads to a demand for output
current at zero crossing output voltage in some frequency/cies.
Amplifiers as well as SOA protection has to handle that situation well, lest
you should get situations like the previously mentioned unnamed amplifier
that had 300 watt in 8 ohms capability on the spec sheet and 11 watts in a
real world load when tested by some magazine that put a scope across the
loudspeaker leads.
Kind regards
