Those Exodus Audio Maelstrom subs look simply amazing. Where would you find one? i had never even heard of these subs until you posted this thread so I won't be much help lol. But after looking them up I can see why it would be a tough call. "better" is a tough term though to have a definite answer to. What kind of application will the sub be going in? Power?
No experience with either one,but after the purchase of my epics im now becoming a huge tc fan. But...you would also have to look at the price difference too. Assuming you would be buying new, The Lms ultra is almost double in price. Would this be more of an ht project or just a general question?
It seems like the Exodus subs are more for HT set ups. Not that they wouldn't work but their Fs is super low which is more important in HT. For car audio use, I think the TC Sounds would do better, but that's just my opinion.
