I have the Bose Companion 2 series, and they sound alright. I find the bass can be very over powering at times, and that's common with all Bose equipment.
I would never pay the MSRP ($299? What for 2.1 speakers) But I snagged them on sale for 1/2 price, which is not bad. Another reason I bought them is the space. They fit nice on the desk, especially near the ACD and they sound decent.
Those Swan M10 speakers really look nice, and I would love to hear them in action. If only we had a nice place to listen to them.
We need a section in the Apple Store for this stuff. Considering mine just opened.
