I have a couple of Fostex FD600 lying around and am considering building a couple of speakers from these, preferably with active sharing. Does anyone here have input/experience with these drivers and what can match? Maybe the Celestion H1SC-9040 can fit as a horn? They are essentially reasonable.

The FE208eZ needs a big horn and typically a high output impedance amplifier to get bass. It goes up to 5k, i’d look for something that gives up some of that top and adds bass potential.
What is your support kit?

Xtz edge a2 300 for bass/bottom. Anaview 0100 for mid/top, shared with Audiolence.
Yes, I also suspect the FE208ez will be too weak in the bass.
I don't have much experience with 2-way. I think it is easier with several drivers that are implemented in AL. Do you have any candidate drivers in a 2-way construction?

You can get bass out of them, it takes something like this: (1867x292x445mm HxWxD)
and a highish output impedance amplifier.
Something like a 10 that can reach high enuff to meet the horn.
A 3-way could take greater advantage of the orns sensitivity as one wouldn’t have to worry about getting bas sout of the mid.
Say a 6-8” midrange and a pair od 10s or 12s on the sides.
Big compromise is more bits means bigger budget.

This will be too much. Looks good then. Nice looking construction 👍, and yes budget with several drivers is precisely a topic.
Just sat down to study Fostex 12W 120 Woofer. This has a nice frequency curve that can match the FD600ez. Was hoping to avoid too extensive construction as I already have this in the listening room.

Paper cone has a kick in the bass that I like. Another option is Seas W26FX002. This, in turn, has a narrow curve so it will be worse to get implemented. Maybe had to get help from larger construction of speaker box.
OK. First some comments: That ringing would keep me away. The curve suggests hard to use above about 500 Hz. No sensitivity given but it looks like aboit 85 dB. You would have to pad the horn a lot.
Looks like 70 litres is about right. Tuning showing is for a nominal room. F10 in the low 20s.
I would look at the SEAS A26 instead. Much smoother, much easier to cross. About 5 dB more sensitive. There is a long thread with some well developed plans, https://www.diyaudio.com/community/threads/seas-a26-devore-style-build.369124/.

I like sealed. Push the woofer closer to the top of the box, leave the tweeter out and plop the horn on top. And i’d tweak the woofer a bit.

Hello,
i‘ve had them on Jabo KH-53 horns about 10 years ago. The Fd600 are very nice speakers and can be crossed at 800hz.
This speakers powered with se tube amps were extrem fun to hear.
