All decent speakers are magnetically shielded these days, so just choose whatever you like.
At the extreme low-end range I suggest the Logitech X-140, they have surprisingly good sound for their ridiculous price of 30$. They can put out lots of sound if need be and are clear in most frequencies. They're also virtually indestructible, very good build quality.
