The patent is complete horse***** and could never be enforced. It goes to show, if you pay the fee, you can get any nonsense approved.
But the guy does have many good points. Most subwoofers on the market are slow, muddy, and one note. And that includes most ID offerings raved upon by this forum.
I also like that he uses Eminence drivers. A lot of them are state of the art and are some of the best transducers in the world. Much better than the Scandinavian companies China bought and are now ripping off builders with complete garbage that have no resemblance to the original inventive European products. In general, SB, Dayton, Peerless, Tymphany, etc. are trash.
And good for him for not giving out any measurements. Building speakers is 50/50% art and science. I never in my life have heard a flat measuring speaker with a flat power response sound good. And I've heard a lot.
Anyone have a pair of Tektons in Chicago area and is willing to audition them?
