Computer Speaker advice

I had a couple of Bose bookshelf speakers laying around and used a Pyle Bluetooth receiver. Works great. And you really can put it anywhere within bluetooth reach. The one I have is small and actually fits my under desk on my keyboard drawer:

If you want cheap:

Logitech Z313 2.1 speakers are decent. They're a little bass heavy, but sound surprisingly good for like $30-40

If you want cheap and versatile:
Logitech Z207 is a 2.0 set that has bluetooth connectivity if you don't want to deal with dongles and such.
They're like $40-60 and make great work speakers. (Won't be so bass heavy for a workspace.)

If you want better sound, you can go with the aforementioned Bose companions, but I think they typically run $100+.
