My house is pre-wired with shielded cat6. There is a drop in each location around my living room where my speakers will be placed. I can replace the wire for the surrounds easily but the fronts and center are placed on an external wall that would be extremely hard to replace. The runs are about 50ft to the receiver in my AV closet. I plan on using two pairs (twisted together) for the + and the other two pairs (twisted) for the -. The room in question is an "open style" living room / kitchen. The living room area measures about 16 x 14.

Here is what i'm thinking o purchasing:

Fronts: Two Polk Audio RTi A5
Center: Polk Audio CSI A4
Surrounds: Two Polk Audio RTi A1
Sub: SVS PB-1000 OR Polk Audio PSW505

This would be powered by the Denon AVR-1613 i already own.

My questions:

1) Will i be losing out (significantly) on quality using the above speakers with Cat6 cable instead of real speaker cable? Would i be better off purchasing cheaper speakers since i can't replace the wiring?

2) Will my Denon AVR-1613 be able to drive the above speakers?

Here is a drawing of the room in question:

Hum are you sure you can't pull speaker wire?
Access from underneath?
I'd opt for some patch and paint work before I used cat cables for speaker level signals.

Cat cable for speakers level is a bad idea for many reasons.
Lack of sufficient gauge, high impedance....

Use this to calculate the required gauge:

A 50 foot run needs at least 18 gauge, which is the equivalent of three 23 ga. wires.
