The SC-IIIA's are almost identical to the Athena/Aletha and the Cantata. The "new owners", before Dunlavy tanked discountinued the Athena, Aletha and Cantata in an effort to consolidate the line. I can't say that I disagree with their decision. The SC-III I always found to be a bit lacking, mostly in the low-end for obvious reasons.
I use mine 80% 2-channel and 20% HT. I disagree with "forever's" comment about running them full range. I have always run the Cantatas full range without any problem whatsoever. You will loose quite a lot if you roll-off the low end to the SC-IIIA. They are spec'd down to around 30-32Hz and Dunlavy's specs are always conservative. If you select the "small" mode for your left/right the bass will roll-off around 80hz I believe. That's a lot to miss for those speakers that, IMO, can well handle that.
If you like the way they sound and I'm sure you're getting a good price go for it. I don't think you'll regret buying these speakers.
