This has devolved a bit for the OP. Classic ASR vs Tekton owners thread. The truth is somewhere in the middle. I don't find Amir to be the most unbiased person, so his comments I take with a grain of salt. He trashed the Sony SSCS5 speakers that sell for $77 regularly, yet have a flatter response than many speakers costing much more. Sure it hits distortion fast with some SPL pushed, but it's a $77 speaker.
Point being, OP, I wouldn't judge either side because of a personal disagreement among two seemingly opinionated and type A people. At the end of the day trust your gut. For subwoofers, rhythmik seems like the king unless you want to take a chance on the tektons. They may be a bigger bang for the buck but return shipping is not cheap if you don't like them. Best of luck to you!
