I turned off all external EQ in my Onkyo TX-NR 1007 receiver (no Audyssey, no dynamic eq, mains crossover set to 100hz, sub LFE set to 120hz) and just measured the pair of Klipsch RW-12D sub's frequency response in my 3500 cubic foot room using my Omnimic and their three native EQ settings. Distance calibrations in the receiver were accurately set. The following frequency response graphs are taken with no smoothing but averaged over 10 captures each from my main listening position (8-10 foot away from the subwoofers). The sub placement for these measurements is one on each side of my projector screen facing outward toward the outside room walls. (this configuration is the best/flattest position I've found in my room) Here are how the subs measured per Klipsch DSP EQ setting.
Note: SPL interval is 2dBFlatPunchDepth
All three EQ overlays (still 2dB spacing):
And the same overlays again using the more common 5dB spacing on y axis
It appears, at least in my room, that Depth
is the flattest Klipsch DSP EQ setting. I would probably recommend that as a starting place for most Klipsch RW-12D owners. I also noticed the quick settings music
mean nothing in and by themselves - you can save or change them to be anything including volume levels, LFE crossovers settings and native EQ setting. I don't know if they come from the factory configured one way or the other, because I didn't pull the subs new out of the box, but in messing with these used subs I determined that only the EQ setting (flat, punch, depth) matters until you save it one way or the other as music
. If all other EQ settings are the same, then the movie and music toggle does absolutely nothing to frequency responses or spl levels. Perhaps Music could be saved as "punch" and Movies saved as "depth" with the other settings (volume levels and LFE 'crossover') varying per individual's subjective preference.
