I would like to sell both my KRK speaker monitors, for I am upgrading my to a newer setup. I would like to get 200 USD plus shipping for the pair. That is saving around 100 USD off the original price. I've had one for about a year, and the other is much newer (around 2 months old). I exchanged it because of a slight hissing coming from the tweeter. Both of these currently have no loud hissing. (there is of course the normal light hiss if you stick your ear right up against the tweeter)
PM me for details and shipping costs
