IMHO, from 25+ years in the AV business and being a hobbyist...
Wireless is not a good option for quality, if you mean wireless speakers. The issue is that they are assumed to be about convenience, not quality. The amplifiers built in to (most) wireless speakers are weak.
Bose is not expensive. So even if you're paying Bose prices for some other setup, you're not necessarily paying a lot. But I have yet to find a comparably priced product that doesn't outperform Bose by a significant margin. They have some useful products, but their standard speakers are not competitive at all. Bose has a couple catch phrases coined by people in the AV business, but my favorite is "Better Sound Through Marketing".
I've had a lot of success with this:
Wireless Home Music Systems and HiFi Music Players from Sonos
The Sonos lets you access many online music services, plus any music you have on your computer(s), and another music source as well. Your computer or smart phone is the controller.
I like their Connect:Amp, which you would then connect any pair of speakers you want, and a powered sub if you choose. I've been told by a reliable friend, but haven't heard for myself, that their Play:5 and Play:3 sound pretty good, but I'm skeptical of anything that small.
Hope that helps.
