Klipsch subwoofer when powered on producing 'boo' noises continuously after short use

Bought from Amazon, and told from an unauthorized dealer and refuse to providesupport.

However, customer is following the Kliptch brand name, and from a reputable Amazon platform, - how can customer easily tell which one is authorized, even with trust of Amazon platform, and how can the unauthorized dealer get the product from Kliptch with a resale margin!? This is just absurd. 

Don't you think it's either Kliptch or Amazon that be responsible for regulating the market, and eventually it's still essentially Kliptch the company itself to protect and honor its brand credibility. this way you are damaging the Kliptch brand, market as well as trust of customer!

It's still Klipsch product within warranty, and NOT a fake one!
