@soix , I actually found those speakers on ebay before you provided the link, and I also found the review on Stereophile. I find this excerpt from the review interesting:
"With its 86dB sensitivity and 8 ohm impedance, the RM22si presented a consistently friendly load to the three different levels of tube power output I employed over several months."
(and the author goes on to describe the amps he used, the lowest power being from the Mesa Tigris--anywhere from 20wpc to 35wpc depending upon which triode or pendode setting he used.)
What I found interesting (bearing in mind that I make no claims to have a real good handle on this stuff) is that a sensitivity of 86 does not seem like a real easy or "friendly" load for a low powered amp to drive. And I am basing that mainly upon the discussions I have followed on this site. (This was what I also questioned about the Totem Arros, a similar looking two way speaker in its own integral cabinet instead of stand mounted, with a sensitivity of 87 but nominal impedance listed at 4 ohms, and 20 wpc to 80 wpc being recommended power requirements.)
I assume that what makes the Joseph Audios "friendly" is that the specs state that the 8 ohm nominal impedance does not drop below 7 ohms?
