FiringSquad has posted a review of the Klipsch ProMedia 5.1 speakers:

The original Promedia v2.400 was replaced by the ProMedia 4.1 with the ProMedia 2.1 as its baby brother. Things that then changed include an improved pre-amp with less gain, and thus lower noise levels, and a slight tweak of the satellite crossovers. Now we have the new ProMedia 5.1, which adds more power with a 500 watt BASH amplifier, and a larger sub with dual 8 inch drivers
