The response looks good for a measurement made in typical room. Although it is unclear what smoothing is being used (e.g. 1/3 octave), there appears to be a substantial response peak in the 35 Hz are and steep low pass filtering above 80 Hz. Moving the microphone position will probably produce a fair variation in response. Measure at the primary listening position and then experiment with subwoofer location to get a smooth curve and then electronically equalize only as necessary. Most listeners try for a response curve that smoothly declines 5-10 dB over the ten audible octaves (20 - 20,000 Hz). Good luck!
