I've not heard the Tektons, but am aware they get a lot of (+ & -) talk around here. So, when I saw a Stereophile review of the DI recently, I skimmed through it. They did get a good review and I believe made the Recommended Speakers list.
However, on the test bench their sensitivity was estimated at 87.5db, which is quite a bit lower than claimed. Perhaps this is one of the reasons there are such varying opinions on these speakers. If you're buying them because you wish to use a low power amp and need "highly efficient" speakers, you may well be disappointed by what appear to be speakers of average sensitivity.
