The TREO Engineering Street Series Extreme is without question the most insane street bass woofer ever developed.  Every component of this woofer was custom-designed to deliver the deepest, clearest, and loudest sub-bass available at any price.  To that foundation we added incredible reliability and unbelievable power handling.

The SSX12.xx is rated to handle up to 2000 watts RMS and the SSX15.xx and SSX18.xx are rated to handle up to 2500 watts RMS.

TREO SSX subwoofers are now available with dual 1 ohm or dual 2 ohm voice coils for greater installation flexibility. A new 10 inch size is available for 2008.
