Key Features :
The Hertz Energy.5 ES 300.5 car audio subwoofers offer a dynamic bass and are capable of outstanding SPL never achieved in this category of the market. The introduction of the V-coneĀ® technology had a big impact in the efficiency of the ES.5 subwoofers, also improving cone stiffness and reducing the weight of the moving assembly, allowing a higher strength voice coil for a higher peak power handling. -
