It might sound like a joke fore some, but the Klipsch R-12sw which in paper are the same as the R-120sw. The R-12sw is just $240 at Klipsch, but Costco have then on sale sometimes down to $140. I have two, and they do rattle my living room just a 1/4 of gain, and the receiver auto eq set them to -15db (I set them -10 to -5 depending of the movie). I would love to see a frequency response and spl test on them.
Note: the room is about 500sq ft and open to another 400sq ft space which then has a open door frame and a large window size opening to the open concept kitchen. (not closed family room and lots of windows).
thanks.
