A great sounding subwoofer in good condition with a ton of options for integrating into your stereo or home theatre system. There are a few dings here and there but it’s in good shape overall and the surrounds are still intact and good to go for years. This unit has an active crossover so you can send everything above 80 or 100 hz to the main speakers and have the sub take care of the very low frequencies. This setup worked really nicely for me and it has a lot of other ways to tweak this sub seamlessly into your setup.
