How long are your cable runs?
Do you plan to run any wire inside the walls, or is this strictly going to sit on your floor?
What type of power will you be feeding them?
Monoprice is almost always a good choice when it comes to cable in general. They have both in-wall rated cable (Access series) and regular cable (Choice series) as well as several options that add features like plenum rating or direct burial ratings, but Access and Choice are really the most typical to use from them.
The price is in line with what most of the industry will charge at 'best pricing' levels.

A lot of people like Blue Jeans cable as well. They are respected and treat people well, but are a bit more expensive for what really isn't going to deliver better performance.
EDIT: Looking online, it appears that Monoprice has about a 10% to 20% price advantage over Mediabridge wire. Crutchfield speaker wire is about TWICE the price of Monoprice! That's insane. Don't buy anything that's just stupidly overpriced without any clear advantage.
I see no reason that the Mediabridge wire is bad, but you will hear a lot of well deserved love for Monoprice for a reputation they've rightfully earned. So, I would spend my money there.
