Home theater arrived with a defective subwoofer.I had to return it to 6avenue the vendor that Amazon shipped it from.Horrible service-still waiting for the replacement subwoofer(3 weeks).6ave has told me 6 times they would ship in 24 hrs.I had to file a A-Z gaurentee claim with Amazon.(still in progress)Stay away from anything coming from 6ave.
