Not sure you have seen this, but this looks interesting

It looks a lot like what Jeff Bagby did with Kairos and later added 10" woofer. Drivers are the same, xover topology is almost the same, even the front baffle tilt is at the same angle. The only difference that i see is notch filters everywhere.

Aesthetics clearly based on Wilson Sophia
I would expect notch filters in a solid 3 way design, at least to tackle box resonance impedance peak for mid driver. The xover actually strickes me as simple compared to some of TGs other designs, I attribute this to the quality of the drivers.
There are not a lot of high quality 3 way Diy designs out there, the cabinets look nice but somewhat involved to build. Might have to give this design a go some time

Crossing mid/tweeter at 1.6K would be a prime opportunity to attempt to use a notch filter and asymmetric crossover to flatten out the wiggle/dip in the response of the MW16P that occurs at ~1.2K. To bad it still rears it's ugly head in the system response.

Im sure itsounds good, but im kind of done with the floor standing robot look of the wilson demi-clones. Thats my new word, use it ifyou must.

That's a beast of a (sub)woofer. I'd like to see that on the side tho, rather than the front.

I have a pair of those woofers, never thought they were anything special compared to Seas L26, etc...

I'll sell you mine for a good price if you still would like to try them.

Thanks for the offer Face. I'm in the uk atm so it'll probably not make sense with duty and shipping costs..
