I have 2 RTi6's, along with 3 other mismatched Polk speakers, that do the home theater thing in my living room, and they do it well, in my opinion. I'm very happy with the sound that the RTi6's produce when it comes to movies and high-def tv, and I almost always like how they sound playing rock music.
On this board I have read the opinion that the RTi series do home theater well, but that they are a little bit bright for music, particularly non-rock music. I play a lot of music, so I'm interested in having speakers that do a variety of music well.
So I bought 2 energy RC10 speakers, and I am breaking them in for about 100 hours, which is the manufacturer's suggestion.
In a day or two, I will compare the 2 speakers using a wide variety of music, and if the energy speakers don't do a wide variety of music better than the RTi6's, then they'll be returned.
I will let you know what my non-audiophile ears hear.
