The HSU ULS-15 mk2 subs are excellent sounding. I had dual ULS’s before and they’re more than enough for 95% of bass lovers imho. I wouldn’t stress too much on getting subs with built-in ARC abilities since the MRX already has it. As another poster has already mentioned placement of subs is crucial to getting the full potential out of your subs. Unless your subs are placed different distances from your MLP Anthem’s ARC Genesis does a great job. Mine aren’t equidistant to MLP so I’m using a MiniDSP 2x4HD and my JTR’s blend better with my speakers now. Good luck!
