Salk SoundScape M5.2 Monitor.
All the other SoundScapes have a moniker pegged off of their woofer size; therefore this could be an M5, a model next down from the M7. It is not a three-way like all the other SoundSaapes but it does have the RAAL tweeter like in all the others. So the ".2" is to indicate a two-way application in the series.
