Sony XS-L120B5D Dual 12" Ported Enclosure Recommendations

The P5 has some unique design features that make it a force to be reckoned with. The cone is made of polypropylene, which is a strong, lightweight and durable cone material. The P5 Turbo Cone design contains spiral ribs for increased rigidity, which also act to virtually eliminate all standing waves on the cone??s surface. Even lower distortion is realized as a result. The surface area has also been increased, improving Sound Pressure Level by increasing the amount of air moved with each thump of the cone.
