I'm considering replacing my rear surrounds with a pair of 6-IW, and noticed that the frequency response on the website differs slightly from the freq response in the downloadable user manual.  Specifically, the website lists the freq response for the 6-IW as 70Hz - 22kHz, while the manual lists the response as running from 50Hz - 22kHz (plus or minus 6dB).  If the website is correct, then do you have updated + or - 3dB freq responses available for the 6-IW?  Thanks.
