Is your idea just to throw a bunch of speakers around the game room for music listening?
If your goal was TV viewing/movies with surround sound, then sell the speakers as they are not appropriate for home theater use. They say right in the description that they are for distributed sound applications in a commercial environment... not home theater. This makes a difference because they are 70v speakers, not 8 (or 4) ohm speakers.
You pretty much gave us the absolute minimum information you could on asking for help.
The BEST setup would be completely different speakers, a really nice amplifier, a incredible preamp, a lossless high bitrate audio source of the highest quality, super nice speaker cable, and a budget of $100,000+.... Since you asked for the 'best'.
Sarcasm aside, you really need to figure out what you want. What do you want to listen to? What are you hoping to accomplish? What is your end goal?
At this point you have some commercial speakers you have in your home, and it seems like you don't know why you bought them. So, figure that part out and you will get more direction on whether they will work for that.
THAT SAID: 70v amplifiers are available on eBay for not a lot of cash which will power all those speakers easily. It will be MONO, not stereo, as that's what 70v systems are designed to do.
