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

Viva a good LR4 with magnesium mid and LR4 with the tweeter as well ! But it's forbidden to mix the sponsors
At 1600 Hz the Seas could be a good match according Zaph measurement : https://www.madisoundspeakerstore.c...xcel-w18ex-001-e0017-7-magnesium-cone-woofer/
After the Sophia SB semi clone, perhaps a Sophia-Seas half cloned, hey ! (at the price of LR4 instead LR2) !
Btw al quadratto Sophia Scan Speak Sister with a Be in the high, a Revelator coated below should be an alternativ...
More and more the OBL-15 seems pretty to me in a dedicated room, although yet a little to low efficienty ! Zaph measured a low 91 dB efficienty with the old 8" Jantzen.... (he measure at 1 W, not 2.83 sensivity ?)

Agree Face. but i was wondering what that is doing to the distortions produced by the tweeter at high SPL

I have an LR4 between Seas magnesium W15CY and Seas T25CF001. I have to say i have heard better.
It is a pretty robust tweeter, but there's no way to know without listening and measuring.
Seas W12CY and SS Air Circ together sound very good.
