I've had these as a spare pair for a ham transmitter modulator for 25 years. They may be unused, but I don't have the original boxes and not really sure. They both test as new number my tv-10 @ about 140%. I also have tested them in the past in the modulator and they sounded great. A little dirty from sitting, I started to clean one, but stopped when the lettering started to go away, as seen in the pic. Sorry, no returns, but the price is right! Shipped and insured USPS Priority to cont. US 48 only!
