Im looking to upgrade to maybe a HSU or Velodyne sub ~soon. The AR sub was bought less than 3 months ago from J&R for $100, I will try to provide the reciept if I find it. It was used less than 10 times, I initially bought the sub to provide a little more bass for music but changed my mind and I decided that I liked the s-direct out of my marantz than stereo mode (which I used more) so the sub was hardly even turned on. It is in mint condition with no blemishes, as if you just bought it new from a shop. The build quality and the performance of this "little" sub will definitely suprise you, check audioreview for some opinions on the AR S108PS. Im asking for $75 shipped through paypal, also check my feedback on Ebay under the username linlkz. Thanks for looking, you can email me at firstname.lastname@example.org.
