any lawyers in this forum care to give an advice?

Might repair of the speakers be a less expensive route?

Just a few questions. Am a retired lawyer, not currently licensed to practice anywhere. So I won't. But  were the speakers visibly damaged upon receipt? If so  why did you acept them? If not visibly damaged, how do you know they are not defective from a manufacturer's defect? Or, were they damaged before shipment and the seller concealed that fact? Each of those three answers could lead to a different approach. At least this happened less than a year ago so there may be a valid warranty claim and the statute of limitations is probably no bar yet. So, not sure I can help.

Do you have unpacking videos?

First question did you pay by PayPal ?

how long has it been since you payed for them ?  
PayPal gives you 6 months ,a credit card only 3 months .

please let  us know , and how much $$ did you spend 

Were speakers in their original box ,what brand , they are all important factors.

last possibility is to file suit in the state they were shipped , i had a trial by phone 

I was in MA , the defendant in WA state ,we had a 3way conversation ,I sent all info 

to the prosecutors office  I win the case  and was paid within 30 days . This was about 6 years ago.

Try making a complaint to your attorney general. In NY, this can be done online.  I made complaints against AT&T and an insurance company and actually got results. It’s free and companies generally listen when they get a call from the AG.
