the Tantric MD is a superb sub. HELLLLLLLLLLLLLLA efficient. Throw it on anywhere from 500 rms up to 1.2k and it will get loud and wang all day.
As with all Tantric subs, it's built with music in mind. Daily first subwoofers here that get loud while doing so
Haven't experienced a SSA Gcon but I've heard an Xcon and the output wasn't a slouch
Never experienced or heard any C2 subs, but for the people running them, they seem to be pleased for the most part
Flip a coin here sir. Heads is Tantric, Tails is Tantric //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif
