Bests & Worsts Reviews from Amazon

I purchased this product in July, 2017 and at first it seemed fine. Reasonably good sound quality in my media room. However, after 8 months it began making a very loud noise; not just a hum. I checked the audio cables, amp, etc and it is definitely in the speaker. OK, no problem, it has a lifetime warranty...right. Well I first contact Amazon to see how to handle it; they gave me an 800 number. However, it was to the distributor. Contacted Amazon again and they gave me an email for Acoustic Audio aka Goldwood Sound. They replied it was the seller's responsibility ie Amazon. Back to Amazon who said...to contact the seller again. I was really disappointed in Amazon for not interceding in my behalf and have left me out to dry. To date I have heard nothing more from the mfg...I don't really expect too. Yes, you can rest assured I won't buy any products from Goldwood Sound and I will now have to reconsider Amazon prime and their "customer service" or lack thereof.
