You hear the name Polk Audio and you would expect excellence. I was mistaken. The enclosures are ultra light. Giving you the feel that they are cheaply made. High range is ok but not that crisp and clear. The Bass sounds absolutely dreadful mainly due to the light and cheaply made enclosures. If you get these make sure you have a sub woofer. You will need it. If you are using these for rear speakers, then they will probably do ok More then likely I will be sending mine back.
