These must be picked up. I do not have the shipping cartons.
I am the second owner, purchased from the original owner about a year ago from this site. The 7/10 condition as noted is conservative - the imperfections are virtually un-noticeable once positioned. One of the grills has a small hole about the size of a pencil eraser, and there are a couple of minor surface scratches here and there. There is a picture of my setup in the virtual systems section here.
All of the drivers are without imperfections - the electronic equalizer bears noticeable signs of wear but is 100% functional. Frequency response is 20hz-20khz, nothing is missed with these speakers and, unlike models further up the Thiel line, these are the easiest to drive. A 100 watt amp or higher will suffice. I have never stressed these in any way.
$500 is appreciably below the Bluebook average of $972.00 and is firm. Heck, current trade-in average is just north of $700. Speakers of this quality are untouchable at or anywhere near this price. For someone seeking admission to audiophilia these truly upgrade a system far beyond the price. Excellent loudspeakers.
AMENDMENTS JUNE 2: I erred in response to the question asked regarding their age. Stereophile's glowing review was originally published in 1989, then uploaded to the web in 2007. I purchased them in November 2015 from the original owner. That would make them around 30.
