Anything But Entry Level

What RE Audio calls entry-level is anything but entry-level. Introducing the new REX series. It offers incredible output and distortion free sound you would come to expect from subs costing far more. REX car subwoofers are perfect for those just entering the car audio scene. Popular among the import and other cars where weight is important, these lightweight subwoofers are an excellent solution for performance vehicles that can’t have heavy subwoofers with large boxes. The mica filled poly cone is stiff and rigid, while the Santoprene rubber surround allows excellent response. Behind the cone is a high temperature 8-layer copper voice coil, a FEA optimized motor structure, and a conex spider that all assist in the linearity of the subwoofer when in use. With a RMS power handling of only 175 watts, these subwoofers do not require a large, powerful amplifier. However, like all of the RE Audio subwoofers, they are capable of accepting much more power then the recommended RMS. For an entry-level subwoofer that is far beyond all the other entry-level subwoofers, trust the RE Audio REX series of car subwoofers to bring great bass in your car.

Awesome Sub

I put two of these in my '03 Tiburon with a MBQuart 5 channel amp. The amp is rated at 500 watts RMS on the sub channel at 2 ohms and these subs love the power. For such a small package, these really put out a pounding.
