This is a good idea for a desktop system. Of course it is not truly a near field array but you should be OK for near listening at a couple of feet from the source. The only drawback I can think of might be how well the small woofers integrate with the tweeter at that distance.

Another thought for a near field desktop system might be a single full range driver such as the Creative Sound Solutions CSS FR125S per side. No close up integration issues with that driver.
