I have a low opinion of the Tekton design principals. It is flawed in many ways; however, the above claim ("build your own clone") truly devalues the work in the design of these speakers. The designer in essence has created a a coxial driver without some of the design problems exhibited by some coaxials (the movement of the mid affecting the dispersion of the tweeter). His solution has obvious flaws, but clearly many like his solution. The crossover design for the "coaxial" driver the design creates is clearly not a simply design that any diy hack can just implement (unless they have access to the actual x-over used by the speaker). So arguing that one can just build their "own clone" suggests that you have a poor understanding of the design.
Why People Like Tekton
I saw this You Tube clip yesterday and I really think this guy gave one of the most well-reasoned explanations of why some people gave up their hyper-detailed "audiophile" speakers for Tekton. I've never heard them myself, but I think the same reasoning applies to many other brands like Harbeth, Spendor, Wharfdale, etc. I personally feel the way he does, but I think he expressed it better than I would have. Eventually, at some point in the journey, you may get tired of listening to the singer's saliva and chairs creaking and just want to relax and hear music in a more natural manner.and not with your ear 6" from the singer's mouth. Or maybe you do. Anyway - take a watch if you have the time. And I'm guessing most of you do.
