I have listened to some dipole/bipole speakers (can't remember the exact brand at the moment). Anyway, on movies they are awesome, really awesome; but if you are going to be listening to music in surround sound I would opt for non-dipole/bipole rear speakers. The dipole speakers are not near as accurate when it comes to music listening, but if movies are your main concern then definately go with the dipole/bipole speakers, you will not regret it.
