Today we discuss Polk Audio PSW505 12 Inch Powered Subwoofer. 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’.

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 a heart-beat-increasing, goosebump-giving bass experience can be provided only when a high-quality subwoofer is added with the components.

A quality subwoofer speaker is the master of enhanced low-frequency limpidity. But sadly there are always little glitches here and there which turn your satisfaction into misery within a short amount of time.

This often happens when your speaker starts giving an excellent result at the beginning but wears out pretty soon due to poor construction or you have to deal with a transitory speaker since most quality subwoofer speakers are too expensive.

We don’t blame you for that, adjusting the quality with the budget often leads us to these mistakes and they can’t be always avoided.
