I have been asking KLIPSCH for two weeks, via two separate emails to send me their FR Plots, On and Off Axis and Complex Impedance data plots, etc. for there expensive RF-7II's for front towers.
Nothing has arrived -- what is KLIPSCH doing?
Geez, I can go to the Philharmonic Audio site, and look at the Phil 3's and see most everything I want.
Thanks to Dennis Murphy, as he cares!!

To heck with Tone controls, if the speaker is designed correctly from the beginning (Drivers, Enclosure, Xovers, Terminus) to be Ruler-Flat for it's FR Plots On-Off Axis with 5 Point Average Listening Windows, even if it has only a Sensitivity of 85db (2.83V/1m), you don't need to mess around w/ tone controls at all.
