I believe a year or two ago, a brick-wall filter was implemented for EP500 at 150Hz (and any of its other settings?). If the 600 has the same brick-wall filter, you will not get a slope (i.e. a smooth transition on the 600 side) at the set frequency on the 600, so as Wid and Sirquack have suggested, it is probably best to keep the 600 at 150/bypass and let your processor/receiver apply the bass management and slope on its side. Doing this would allow you to slope into MBM and 600.
