When buying used speakers are cosmetics important to you?

Seems a good deal.  You could probably reduce or remove the scratch to make it less visible or completely disappeared.

Really depends on the damage.  Surface scratches that are difficult to see unless fairly close or a specific angle?  Ok. A ding or broken edge or similar on the back?  Probably ok.  Deep gouges in the finish? Probably not unless I can hide it or patch it or the price is just insanely good versus the performance.  Anything more substantial than that is probably a no.

Function over form, within reason. A scratch here or there isn't a big deal. Peeling veneer? Not an issue. But, anything cosmetic will affect resale if you go that route as most humans are form over function. People buy cars and dogs and all manner of things simply because of how they look. Why do you think D'Agostino makes the audio jewelry? So he can charge a lot more for it. Put all that in a plain black box and it wouldn't sell nearly as well at the prices he charges.

I'll bet at 74 you might have a few scratches as well.enjoy your new found love in that speaker and the sound.keep healthy and enjoy the music. Now give us a followup on how you like the sound
