The model I have is the v.2-400, but I know they've come out with some new ProMedia 4.1s recently.
Anyway, I got them about 7 months ago, and they cost me ~$260 w/shipping and handling. The sub is rated at 160 watts RMS, which provides for some pretty impressive bass action. You'll be melting in your chair if you crank them up loud enough.
Alternatively, I could probably give a really old person a heart attack if I put the sub to their chest.
