OP contact the manufacture and see if they are available, FIRST. Ask what is the wait time and is there an alternative. Don't wait. I would also ask the manufacture's tech department what they think. Don't bellyache to the tech, just ask what would cause TWO tweeters to blow?
1. oscillating amp
2. WAY to high of volume.
Result:
Blown tweeters and possible crossover.. ASK THE TECH!!! You'll see..
It's not a broken wire for god sakes X 2!!!! Fix your speakers or dump them broken, but don't wait..
There is only so much time to file a dispute.
Second, there is no warrantee if they been sold 2 times. There is a friggin' reason they were sold TWICE, RIGHT? He's trying to get you to do something illegal. That is what is really happening. Make him aware, he gets to pull that one off and can sell you the tweeters if he gets them before you do.
Understand YOU dictate the terms not the seller. Refund the money for the tweeters UNTILL they show up and 300.00 for installation. That is a good compromise until they actually come in. 6 months my A$$
I'm not gonna say "Sucker" just yet.. But we're getting close.
If it's in the states, I'd fly there, no kidding, if he's still there.. :-)
Come on dog, time to feed the chickens!
