Quick Amp question

[Pycroft]

Does an amp have to say that it can handle a 6 ohm load to power them? For instance, my Soundcraftsmen amp is rated at 205 watts for 8 ohms, and I believe 325 watts for 4 ohm. It says nothing about 6. I'm assuming if it can handle 4 ohms, it can handle 6, correct?

Thanks.

Yes.....

Yep, that Soundcraftsmen will power just about anything. Remember, speaker impedance ratings are "nominal" which means an impedance of 8 ohms is just an average over the frequency band for that speaker.

To better illustrate, here's a Paradigm Ref Studio 60, rated nominally at 8ohms, note how impedance shifts with differing frequencies (solid trace). This one sweeps from 3ohms minimal (@ 200Hz) to a max of 23ohms (@ 75Hz):

I'm not sure I understand that. It's okay though, not all is meant to be understood. George says he know what people would say...well let's see.

What would be better to power SDA 1C's - the Soundcraftsmen PCR800 OR a B&K ST-140. Anyone have experience with either of these amps actually powering these speakers?

Thanks
