Verified Purchase(What's this?)
This review is from: Polk Audio RM705 5.1 Home Theater System (Set of Six, Black) (Electronics)
These speakers are wonderful; I wanted a good speaker system set and I took a look at forums but I'm happy I got these for about 300.
-Subs is perfect for me
-Speaker are very beautiful and match with TV
-Sound is amazing; now I can hear the bits and the bangs of my blu-ray movies
-I have no cons so far
Tricks for good sound from these bad boys:
-Turn the sub's cross over all the way up
-Turn the phase nob to 0 degrees
-Turn the receivers cross over to 80hz
When you are done, listen to the system and if there is not enough boom from the sub turn the channel level setting on the receiver for the sub a little bit. Listen to it, turn sub level, listen and so on until you find your taste.

Actually set the cross over to 140hz!!! The Polk RM7's only work as low as 95hz, So you have a frequency gap from 80hz-95hz

Why would a person want their sub producing frequencies over 50hz? That's the highway to boomyville and will make your whole setup sound terrible. You're better off losing those ranges than pushing them to the sub. There's a reason speakers are often called mid-bass drivers: they're for middle bass frequencies. Subwoofers are not. If you're shoving 20 different frequency signals at your sub, it's never going to be able to move air fast enough to accurately produce all of them.

John actually the general accepted crossover for subwoofers is 80hz. Frequencies below 80hz are not localized. THX systems in fact are built for the 80hz crossover. Sorry but John you have no clue what you are talking about
Boomy-ness comes from room acoustics and positioning. Corner loading a subwoofer results in boomy bass more than a high cross over.

Two simple questions. Is it a powered Subwoofer? My bro's browser doesn't seem to have a cntrl+f find function. And do speaker wires come with this system? Someone in the reviews said that it doesn't.

No speaker wires and yes the subwoofer is a powered subwoofer. You need a receiver to use these speakers

I am wondering how these speakers sound like with music? As I know many 5.1 speakers don't perform well with music.

Really depends on the size of your room. Though if music is your main goal a pair of bookshelf speakers and a subwoofer is much better choice

The actual RM705 manual says to set the crossover frequency to 120hz. There is no way those little 2.5 inch drivers on the speakers could go as low as 80hz or lower. Like R. Martinez mentioned, you will have a frequency hole if you set the cross at 80hz.
