As Kal mentioned, REW can prescribe filters. But the success depends on how you configure REW after the measurements have been made. Some key steps:
Treat the subwoofer EQ process differently from the main speakers. The goal for mains is to smooth out broad EQ differences among the speakers. The goal for the sub is to kill sharp resonances, and set an overall response curve.
For the mains, measure once for each speaker. Set the REW smoothing to 1 octave. In the EQ mode of REW, tell it you have 5 bands. set the gain for the filter generator near the lower end of the response curve so that it will induce REW to use EQ peak reduction. (The SSP-800 EQ offers 20 dB of cut range but only 3 dB of boost -- as boost is almost never a good idea).
For the sub, measure several locations within a ~2' diameter. Use 1/12th octave smoothing. Average the results. Let REW prescribe filters.
Sorry, have to run, but just wanted to give a thumbnail of the process.
