I'm sure it depends very much on the program material. For a studio vocal recording, I doubt that there would be much difference at all. But if it's a big hog organ going full tilt in a church with lots of ambience, the difference wouldh't be very subtle.
well, what can I say now?
I listened both speakers playing some big band recordings with a female vocal and a double bass, and also some drums. No pipe organ, nor electric bass guitar. One thing- Frank's switch box levels the output of the speakers, so the sensitivity did not matter in this case. So, I did not hear
much difference between Silk and SS8 as Dennis said. I actually asked Jim about it, and his response was like Silk had softer presentation (that is why they picked the name), while SS8s are more resolving, full range speakers. Jim could probably explain it better. I think that SS8s are slightly more detailed and accurate in the midrange. I did hear SS8 reproducing very deep and clean bass notes on the other tracks. Cheers!
