Precision Power Pro12 Flat Piston Subwoofers

This auction is for a pair of 8 ohm PPI Pro12 flat piston subwoofers.  These subwoofers are used, and in good condition.  Each works perfectly, but they do show signs of aging.  The forged steel back plates are scratched, and the other soft parts are dusty.  They are VERY heavy, so shipping will be higher than many woofers. 

These woofers are rated to handle 300Watts RMS, but the Gates' Bronco used 64 of the 10in versions and they were fed 700Watts RMS each with no problem.  This speaker design shattered all previous records for both SPL and sound quality.  The flat piston design easily plays into the upper midbass range, and in a proper box will play very deep bass with ease.  I must warn you, these woofers are very inefficient, and need plenty of clean power to work their magic.
