I want to buy new speakers for 50,000 and see it used for 30,000, what should I do?

I saved 13k on my current used speakers. Only reason I did it is I was able to drive to the seller and check the speakers out before purchase. But getting them shipped without checking them out, count me out. Items under 5k maybe.

Not a good feeling paying 50g for something that your expected to realize a 20g opened box devaluation. Given today’s market not even caring what brand or model I highly doubt they were worth 50 when new. At that price one would think you’ve spent Considerable time listening and like what you hear. If the money is there and cost doesn’t matter… It doesn’t matter. If you’re feeling pressure and sitting on a shaky fence perhaps that budget is telling you something. Definitely a personal thing, good luck with that.

Cheers

If the product is available on the used market you'd be a fool for not looking at least. 

1. WHAT speakers? You never said.
2. Everything depreciates. And speakers at that price level are boutique, not appealing to very many consumers. Most people buying them are rich enough that they are NOT "stretching" their budgets to buy them, so they’ll buy new, sight unseen and likely they’ve never even heard them. They are buying them on some dealer’s recommendation. I recall the story on here of Elon Musk blowing the hell out of some speakers or amps because he didn’t have a clue. He was just wanting good sound for playing video games.
3. If you want to save $20K, spend a day and go see and hear them in person. Play them well with music you know at various volumes. Examine drivers, cabinets, smells, grilles, everything.
4. How will they be shipped to you? Buy the damned insurance and insure them for $100K, just in case.
5. Everyone has price ranges they are comfortable with. If you were considering $50K, but now have pauses because in 18 months they are only worth 60% of new, then I wouldn’t buy them.
6. Does depreciation really matter? If you bought them at $50K and kept them 10 years, what is the problem? Will these be your "end game" speakers?
7. I often see old 1980s and 1990s "vintage" speakers going on Reverb for MORE than they cost originally, factoring in inflation. People are dumb or too nostalgic if they cough up that money for something 30 years old with questionable crossover components.
8. OK, so you found ONE seller asking $30K for them. That doesn’t necessarily mean there are 20 people out there that would sell them so quickly for that amount. You don’t know the person’s reasons for selling them. Maybe their dog peed on the drivers. Or, maybe they are going through some tough times and need cash and are willing to take a hit to get that cash. Maybe there’s another "plaything" they want to buy more important to them than these speakers.
9. Life is short. Make a decision and go with it. Either way it isn’t the end of the world. Enjoy.
