Hello,
You may need to get some interim speakers for now. You could open a dispute with PayPal but in the end you loose the deal on the speakers. Everything in audio is going through the roof in price. I can’t imagine what these all aluminum speakers cost now. You might be giving up a once in a lifetime deal due to current prices. Last thing is try to find some tweeters on eBay or AGon or something else to get them going. There might have been a pair of these speakers or another model with the same tweeter that has serious cabinet damage. That’s how I got a hinge and sub platter for my Linn TT. Not cheap but cheaper than new. I hope this helps and this all gets resolved soon.
