I looked on Apple's site and most speaker sets are ridiculously overpriced. I would want to spend in the 150-300 range and have a set that has good sound with hopefully a decent sub. I haven't bought speakers for a computer in a long time, with my last set being a creative 6.1 that had like 5-6 audio connections. Is everything blue tooth now or does it utilize USB3 or thunderbolt? As you can tell I'm quite a noob at audio in modern macs. Thanks!
