Hi guys I have a FI 12" SSD D1 with copper coils for sale. This was last years model when you had to pay extra for the copper coils. I'm sending FI and email to see if they still have the specs for this sub. If they don't I'll post the ones that i have in Winisd. I had the sub in a 1.5cuft sealed box ran off an ESX 275.2 (which is rated at 700 Watts at 2 ohms) crossed at 80hz and below for about 7 months. Its got a few scratches on the basket and motor from being pulled in and out of the box. The rubber gasket has a few spots where gluey fingers touched and a few scratches from getting most of the glue off, this part can be replaced easily. The rest of the sub looks really good but if you look real close you can see two spots were something rubbed up against the surround, nothing major, and it doesn't effect performance. I have the orginal box that was sent from FI to me. Id give it an 8.5/10 apperance and a 10/10 performance. Im Looking to get 145 + shipping and I'll pay the paypal fees. Also open to trade offers. Now onto the pics, if you want more just pm me.
