So, I have my new black matte RAAL Towers. I am in the process of doing an AB comparison with the Spatial M3 Turbo S, but I am already starting to plan a sub pairing.

Should I do the sealed 12? The compact sealed 15? Or...maybe even consider a pair of the F8 dual 8s? Who is happy with their RAAL Tower sub pairing? My room is roughly 18 x 28 with a high ceiling.

I will be either be running the Marantz 7702Mk2 with separates, the Denon 7200WA, or maybe the emotive if they get their stuff together in the next month. I'm interested in your suggestions here as well.
