what can I expect the sonic differences to be between the SEAS 27TBFC/G and 27TBCD/GB-DXT? I would like to make a two way with an 8 inch woofer.
The DXT is a lower HD tweeter than the TBFC. It sounds better too.
If you want a kit with the TBFC with an 8" woofer, it might exist already. The TBFC was pretty heavily used about 15 years ago for such an exercise.
That said- 8" 2-ways are not the easiest designs to accomplish.
Good luck!

^^^Designed 3x 8" 2-ways, of which, 2 of the three were definitely better than the 3rd.

Wolf_Teeth thanks for the advice. What makes the 8n inch 2 way difficult? The large size woofer and getting high enough to reach the tweeter? If so should I consider a smaller dia driver or do a 3 way?

Woofer doesn't want to go high.
Tweeter doesn't want to go low.
Center to Center distance is long.
Directivity mismatch around xover point makes blending difficult. Waveguides can minimize this, or use clever FR manipulation to minimize this peaking.
The breakup of the woofer, especially if metal, can really a be a problem.
Fs of the tweeter and Xmax potential can be problems when reaching lower.
And of course- size of 8" 2-ways can be massive for stand-mounts lending them to towers. Of the 3 I've done (pending more), one was 2ft^3 tower, one was 1.2ft^3 stand mount, and one was a 1ft^3. I've seen others that were bigger.
Not saying you CAN'T build one. Just saying they have challenges. If you just want to build one and not design one, there are several available in kit or non-commercial-use information.

It can be like there is a gap where they don't join up, because the big woofer gets narrow at the top and there's not enough of it to go around.
A good option, because it allows you take the woofer higher, and it helps the tweeter to reach lower.
A good 8" to use would be the Scanspeak 22W/8534G00
Tweeter with no waveguide: Peerless DA32TX00-08 1-1/4"
Imho the DXT is a better match to a 6-7” woofer. Both because directivity matches better on logic X-over points and the baffle can be optimised more.
That what I thought, just too big a driver for a 2 way. I guess one can always insert a small mid and make a 3 way (i.e. 3 inch SEAS cone).
But I have a better idea. Since I am advised to use a 6-7 inch woofer I can use my MW16P with it. Does that have potential?

If you want to build a 2-way using your MW16P you might want look at either Jeff Bagby's Kairos or Adelphos. They both use that midwoofer and what is reported to be an outstanding Satori tweeter. The difference is just between a sloped front cabinet and a straight one.
