The speaker company - 2 choices

[Fors]

I am setting up a 3.1 setup, my first venture into home theater. I have a low budget so this is what I am working with. I have ordered the Denon AVR-1610 receiver, its on its way. I plan on getting this sub from TSC http://www.thespeakercompany.com/ASW...er-P62C17.aspx.
One question I have is what kind of wire do I use to hook the sub up, do they use normal speaker wire or do I need a special cable for it?

Now the main question is there, hopefully anyone who has experience with these speakers can chime in. This will be for left/center/right.
Option 1.

Option 2.
http://www.thespeakercompany.com/RC1...er-P38C37.aspx and http://www.thespeakercompany.com/P6-...ir-P37C37.aspx

Which would sound better? I plan on adding maybe a pair of the P5 or P6 at a later date for rears, but that could be over a year off, after we move out of this apartment.
