This auction is for one Alpine Type R 12" subwoofer with a box. The box is vented, which is reccomended for this type of subwoofer to get the best sound. The box is made by QLogic. I bought these at the same time and both were professionally installed. The box and sub are in excellent condition with no markings, was only installed for 3 months. I spent alot of money on this system and take good care of my things. Asking $150.
