You would need some kind of amplification for these speakers. All depends on where you are getting your music from. Do you want to control it from that room - i.e. have a CD player, phone dock etc. right there - or just have extension speakers and control the program from somewhere else?

If the former, you need a receiver of some kind in the room. Run all the speaker cables to a panel on the wall where you want to put the eqpt.

If the latter, you could just have a volume control in the room and control your program from elsewhere.

There are wireless options too. You might want to look at Crutchfield or Parts Express and see what kind of gear is available.

Oh, and I would think about 4 speakers would cover this kind of space, maybe more but probably not less.

That's super helpful, thanks! We're planning to control it in the room, we'll have a built in media cabinet in the corner.

We put 4 speakers (8-inch) in the ceiling of our basement gym, and connected them to the Sonos amplifier. The speakers were relatively inexpensive, and while I considered adding 6-8 speakers throughout our space, the four units ended up covering it well.
