I bought these to be the surround speakers in my home theater system & definitely made a good choice. My speakers are all Polk Monitor series tied to an Onkyo HT-SR875 Receiver (also awesome). The thing that really stands out is how absolutely clear and pure the sound is from the Polk speakers. When watching movies - the soundtrack sizzles and the dialogue is crystal clear. While watching the Superbowl - I heard this funny popping noise coming from the opposite side of the room from me -and then realized I was hearing someone at the game, sitting by a microphone and applauding. Clear as a bell.I don't think I would like these as well for a dedicated bookshelf stereo speaker - they reproduce mid to high range well, but don't have much bass response. Paired with larger front speakers, a center channel and a good subwoofer, they help create a really terrific home theater experience.
