What is the best way to sell B&W speakers?

USe auction when market value is not clear. Use classified when it is. Agon blue book provides retail and actual market values based on historical sales records. Most B&W speakers will have a lot of historical sale data points to help establish the market value, so go classified in this case in order to quickly sell for teh fair market value.

Sometimes bidding wars develop on certain popular auction items for no real good reason and there is a chance of getting more than current market value. Its a risk that might be worth taking in some cases. Of course, you might also get less, or not sell at all if the minimum initial bid is set too high.

Auctions usually benefit from a large number of participants. I would only use agon auction for something with potential unique value for many audiophiles. Most b&w speakers would not qualify. eBay would be abetter option due to large number of users. I have always had good luck selling audio gear for a good price on eBay. Have not had a reason to try it on agon yet. I have a Dbx 3bx that I am not using that might be a good candidate but I suspect eBay would work just fine.
