I kind of depends on what you value the most in the sound you like to hear, but I think Tyson, Danny and others who have heard both would say to go with the NX-Oticas and don't look back. What is consistently said is that the NX-Otica Tower is richer, has more weight, in the lower mid-bass area than both the MTM version of the NX-Otica and the Super Mini. This is with all three having servo subs to cover the bottom end. Now when Danny comes up with a solution for the new bass module for the Super Mini, that perception might change. Honestly, hearing how much Ron and his brother loved the NX-Tremes (even in some ways over the Line Force!), I think you are very safe in going with the NX-Otica Tower as it has very good DNA. If you can afford it, and have the room, go for the NX-Tremes.
