I set my T/9X RELs according to the bass frequency response of my Wilsons which meant an approx 50 hz setting. The test results posted for the Wilsons seem to show a pretty bumpy bass response where there is a 10db dip at 20 hz but a strong rise to a peak of 50 hz. My gain is very low so it augments here and there but has added to the spatial response in a nice way.
