Hey all - been lurking a bit here but came across a pair of KEF LSX ii for $500 - only photo is linked above. Seems like a steal from my novice understanding. Would be my first time buying used speakers curious if you think these are worth going after at this price and any advice you have for:

• things to look for in pictures for damage/concerns
• things you'd ask before driving 90 mins to see them
• things you'd check before buying
  • checking function ofc on wireless, but i'm unsure if I'd be able to check all the analog inputs/outs etc

Thanks in advance!
