Polk RTi4's or 6's vs FX3's or 5's for surrounds?

Hi guys,

I'm thinking of surround speakers to finish up my HT setup. As my signature states, I have the RTi12's and the CSi5 center is coming when it is available. Back-ordered right now. Now I've already spent more than what I wanted to on the front 3 and the receiver so I'm in no rush which is good cause I can do some research.

Anyway, I was considering the RTi4 or 6s for surrounds. They sounded pretty good for stereo when I auditioned them. My question is about FX3 of FX5's. These are apparently dipole/bipole speakers. What is the advantage to have these are surrounds? I'm sure since they were specifically design to be surrounds, I anticipate a better sound field? Does that make any sense. Anyway, I just wanted to get your opinions on these. Are they worth the extra $$$ over the RTi 4 or 6's?

If so, what is a good price to pay for them? I find the Polk MRSP way out of wack, especially on all the sales going around online. Cheers!

I personally don't like bi/dipole surrounds. I have only heard two systems that I felt sounded really good using them; one of them was over $100K. Some like to have a very diffused sound from their surround but I found that I prefer the more precise, directional sound that comes from a monopole speaker in surround duty.

Your room is a factor also, if you don't have a near rear wall to bounce some of that back sound from a bi/dipole when it is mounted in line with the listening position, you will not get the proper effect.

Thanks for your opinion. The section of the living room dedicated to my HT is not huge. I have 10 foot ceiling. I would say the dimensions are 15x12x10. There is a back wall, left wall, and front wall, the right side is open and I was going to put the speaker on a stand or a table and set it to the height of the other speaker.

I guess di/bipoles would have an issue with this setup right? hmmm... any one try bi/dipoles on speaker stands as surrounds? do they have to be on the walls?
