I purchase this unit about a month ago . when I try to hook it up , the wireless woofer would not respond to the sound bar . I contact tech support , who take I through the step to set it up . when it still would not work , they have I ship it back to they , and they would replace it with a new one . when the `` new one '' arrive , -lrb- with a lower serial number than the first , in a box that do not appear to be new -rrb- , it would not work either . I be send this back today , hopefully at some point I 'll either get one that work , or a refund so that I can buy something that do work
