I have read no negative speculation. However, I have seen how they are made and what I said is what I recommend. All speakers will sound better if time aligned, and use better parts, more dead cabinet and have diffraction control. I have been making speakers since the 70s. Heck, even the Dalquist speaker was time aligned. This is nothing new. I do not hate anything or anyone. I love everything and everyone. We are one. We are ALL beautiful. I am sure your Tektons sound great. I just know how to make them sound even better. Or better yet, make your own fully open baffle planar mid/highs speaker that will be better than pretty much any box speaker.
My friend owns the Ulfberht. I helped him design a wild outboard xover like yours and he also felted around ALL the mid/tweets for even better sound. He loves them. However, the drivers still need damping, the cabinet needs to be deadened, the wiring needs to be upgraded, he needs to wire directly to the voice coil wires on the woofers (use no tabs)........it will then be even better. And all xover parts, jacks and wires should be cryoed, as well.....way more info. However, no matter what you do.....the woofs will never be time aligned to the mid/tweets and in the Ulfberht the big woofs and little woofs are not time aligned to each other. Check out Dunlavy and his super time aligned speakers from the 90s. BTW.....it sounds much better to run the signal through a coil.....from the inside out. That is: into the inside winding and out the outside winding. So the outside winding should be towards the driver or ground.
