A long time ago (about 1979), I purchased a brand new pair of Monitor C7's. They were my second pair of speakers on my system and I didn't use them much. Long story short, I moved a couple of years later and put the speakers in an upstairs bedroom closet where they have sat ever since. I'm moving again and I just got them out and looked at them critically. They look brand new - not a mark on them anywhere. My new place really doesn't have room for them either so I guess I should part with them. Any idea what they are worth? Is eBay the best place to sell them? What are expert buyers (i.e., folks like you that know Polk) looking for? I've read some stuff on here that the particular tweeter they have is of importance/concern. Anything else? And how does one go about shipping such beasts without destroying them? TIA for any and all responses!
