Polk Audio PSW505 12 Inch Powered Subwoofer Reviews

What is the definition of the ‘perfect bass’?

When you turn the sound on and those cones of the components start to tremble back and forth with every wave, when low-frequency notes make a smooth but deep “boom boom” sound without any distortion or unpleasant noise, that’s when you know that you’re experiencing the ‘perfect bass’. And when you experience this in your car, you can officially claim that you’re an honorable member of the “Car speaker master race”.

You can easily become the owner of the best stereo system with pleasant bass quality if quality woofer components are already included in the system; but heart-beat increasing, goosebump giving bass experience can be provided only when a high-quality subwoofer is added with the components.
