Have you played with speaker placement to mitigate room issues? I think the SVS SB1000 Pro is a better (and cheaper) sub than the 3000 Micro and isn’t all that much bigger. The REL doesn’t go all that much lower than your speakers but may still help within its limitations. Personally I’d go with the SB1000 Pro as I think the bottom octaves the REL doesn’t have can contribute significantly to imaging, soundstage, and sense of space, and it comes with their helpful app for easier integration and has a 45 day risk-free trial (including shipping both ways) that I’d definitely take advantage of. BTW, I have an SB2000 and it’s very good especially for the $$$. Just my $0.02 FWIW, and best of luck.
