Jer,
MicroWalsh speakers will play fine at low levels, but I'm sure it will be hard to resist playing them moderately loud once you've tried it. I was quite surprised myself, how loud they can play clearly once we'd built the first prototypes and brought them to our home testing theater/listening room. Though they are small speakers, and designed more for moderate volume level listening in apartments/condos etc, or as surround/rear speakers to go with larger Ohm Walsh mains.
In response to Sean: No, they are walsh type speakers, omni directional over much of the frequency range.
