WTB two 12 inch subs

I have a pair of Oz Audio Matrix 300L 12" woofers for sale. They are similar to the old Image Dynamics IDQ series. Needless to say, they are excellent sq subs. Contact me for more information, or just follow the link below.

Introduction

Never again will you find a better driver for less money! The all new dB-500, offers you the absolute most bang for your buck that we can possibly provide. This amazing entry driver shares many of the TC-1000's defining features including the beefy 135 ounce high performance motor, a high thermal four layer aluminum 2" voice coil, and up to 2” peak to peak excursion. This driver is built to last and we construct each with the same standards as our high end speakers. The dB-500 simply can’t matched for this modest price and best of all, we're still building this driver in house right here in San Diego California.
