This Lanzar OA10 subwoofer is a great addition to any car audio system. With its dual voice coil and 10 inch size, it provides powerful and clear sound. It's a vintage piece, made in the United States with a RMS power of 150W.  I purchased this over 20 years ago for a project that never happened. Still in excellent condition.  Please See Pictures.  Other Lanzar Speakers Available.  Check Out Our Other Listings.  Combined Shipping Available.
