For a long time now, Phoenix Gold has been producing top quality, high performance car audio products. Over the years, the brand has earned a reputation for rugged, ‘over-engineered’ gear that’s designed from the ground up to handle the abuse of its most enthusiastic customers.

The new SX series of subwoofers is a great example of this philosophy. Built with larger-than-typical motors, heavier steel frames and large diameter voice coils, the SX woofers are designed to sound great and handle pretty much whatever you throw at them.

The most popular model is the SX112d4, a 12-inch dual voice coil subwoofer with a suggested retail price of around $300. We put one of these woofers through the paces here in the lab to see how it performs.
