I am shocked at the lack of reviews around the Airmotiv S12 and other subwoofers. The S12's small size intrigues me for a dual sub music setup. I just can't seem to find any detailed info on the sound quality and how it would stack up to the cheaper Rythmik L12. Which sub is going to have more output? Does the Emotiva keep up and stay clean with music compared to the servo tech in the Rythmik?
