These are in great condition, with the original paper cones and not the later poly cones (I have had both and the paper sounds WAY better). No scraping from the coil gap and the surrounds are perfect - no deterioration whatsoever. The DC resistance on the coils measures 6.3 & 6.4 ohms.
I looked on ebay and priced them according to just one ($200) refoamed later model polycone that looked pretty lame. These are worth way more than that. Shipping will be a well packed 20 bucks US, but will consider other destinations. Parameters may still exist online, I just don't have them but they can be used in a ported enclosure, sealed box, or with the Dynaudio Variovent and take about 150 watts RMS with no problem. Linear excursion is 1/4 " and these are legendary for their speed and accuracy.
