Go off the Richter Scale with DBXi Subwoofers

The DBXI-15 Single 4 ohm 15" subwoofer is the perfect example of what it means to carry the Earthquake Sound name. Earthquake Sound subwoofers need to not only be loud but also sound great and perform without any problems. With an RMS of 750 watts this woofer will produce enough bass to really satisfy those low-frequency reproduction needs. The woofer features a pressed pulp fiber woofer cone and high-roll rubber surround for added stiffness, rigidity, and higher excursion capabilities. Its turbo propped cooling reduces thermal heat and thus increases output and lowering distortion during all periods of play. The woofer also features a 2" voice coil and double stacked magnet structure able to produce an impressive 3.5" of linear excursion, giving you deep impact bass. The DBXi woofer is your everyday driver that will perform day in and day out without compromising quality.

Earthquake Dbxi

I was looking at this sub a couple years back when they where retailing for 400+$. I just got it for almost half price. I just did the install today and bought all my goodies through Sonic. Everything arrived on point. Sub quakes if you build a decent box with the right specs this thing will keep up with the competition for a third of the price. -durability to be tested ;-)
