I purchased this subwoofer form an estate sale and the owner told me that it works great. I wasn't able to test it myself because I just sold my last receiver so I honestly don't know. By all appearances it looks to be in great condition. If there are any issues with the item upon arrival please let me know before leaving feedback as I strive for excellent customer service. Since all I have is the owners word and the fact that it looks great , is the reason in the low price I'm offering. If you have any questions please message me. Once I'm able to properly test it I will relist it for a higher amount. For now I'm selling as is. Thank you
