I measured the frequency response of my EP2500 using REW and thought I'd post it here. I have seen it done in at least 1 other thread but another won't hurt. Sound card is calibrated and output level was set to 1Vrms, output was unloaded.
The full range measurement with SSF set to none, 30Hz, and 50Hz
The SSF matches 12dB/octave pretty well
