Seems a good deal. You could probably reduce or remove the scratch to make it less visible or completely disappeared.
When buying used speakers are cosmetics important to you?
I have an opportunity to buy a pair of used Totem Element Metal speakers that retail at $20k for $5k. They are flawless from a performance perspective but have cosmetic imperfections such as surface scratches that are not visible from the listening position, thus the price.
How important are cosmetics to your purchase of used speakers?
