This is a new JL audio competition 12" W7 sub woofer in an amazing ported box! I've had this in my car for about 3 weeks and just realized it is too loud for me! This was originally purchased for $1100! The sub itself retails for over $800! JL is known for their quality, sound and durability and this sub is NO exception! This is a great sub that is very loud and can be yours for only $600! Thanks for looking! pm me ..
