Velodyne VX-10 - Any good?

Options
I see one on CL for $65, looks decent. Planning on using it with an Interga 4.6 and Pinnacle PN6+ speakers, or Yamaha CR800 and Monitor 5s. Is it too small for my intended purpose. How would it compare to a PSW111. I could use that and goo bigger in my HT. What do you think?
