Daggar Audio Cones
I did purchase several cones to test before building the FAST TLs. The flexible vinyl ones seem to be the "deadest" when I drum on them with a wood spoon (Very Scientific). When you cover the regular thin 9" plastic cone with bytul on the outside and 1/2 thick melamine sponges on the inside, it works great: completely dead. That's what we used on the FAST TLs.
XRK has told me that there is a significant advantage to a five sided pyramid, so I'm just going to build those out of 1/2" wood in the future. Should we be designing a 5 side pyramid for 3D Printing?
Here are the Vinyl ones I tested and the plastic ones I used.

Oh yea !!!!
2 x 10f's on the way !!!!
Huh, had my wife order.
In my excitement, i hope we ordered the 8 ohms.........
I'll check tomorrow, lol.

How about letting the 10F "breathe" - maybe it'll bring an improvement similar to the bass driver. Maybe a tiny transmission line for the 10F?
Years ago I did a study on the differences between a open ended short TL vs a sealed Dagger and the measurements did not show anything and the listening tests did not show any improvement. It might be that the cone does not move enough to matter. On the RS225, it needs real movement and also, the cone is thin aluminum which might require-transmit back reflections easier than damped fiberglass.
I'm ordering a few drivers from SBA's local distributor.
Since it is really hard and expensive to get some RS225 to my place, I've figured the best alternative is the 5x8" racetrack woofer from SBA.
It sims quite well in a MLTL, pretty close to the RS225 in fact, and I have to figure out which FR will go under... either the SB65, or the B80, both of which I have and love listening to.
My only regret is the distributor doesn't have the new 4" coax from SBA... looks interesting.

The B80 was pretty nice with this setup. I think it has a nice performance/price ratio. Ultimately, the 10F is tops due to its very low distortion and glass-like smoothness. Good luck with the SBA racetrack woofer. The look is not my favorite though but let’s you use skinnier width baffles.
That's the plan. Put the woofer vertical, and choose between the SB65 or the B80.
When crossed high enough, they should provide distortion-free music just as well.
The racetrack style is growing on me! 🙂
I like the B80 for vocals, but the SB65 is so killer with stringed and woodwind instrument, it's mesmerizing.

There really is something fetching about that shape and for years my go to low woof was a KEF B139.
I just looked at the SB Acoustics SB15SFCR39-8 on Madisound and there is a matching passive radiator SB Acoustics SB15SFCR-00. Interesting.

Oh, I finally received the SB10PGC21-4 !
Took a long time!
I'll be able to fare it against my B80 and the TC9. Cool!

two in a mini-k would bring it to 8 Ohms.
My plan is to compare them mostly in the Nola Brio clones vs the TC9 (and B80).
And probably off axis 15 deg might make it ruler flat to 20kHz.
Tests are coming!

We never see the back of the drivers... this is a handsome one!

no holes....
But the wiring tabs are mounted each side, so it should make some nice clean wiring for a line array.
I just had fun and put one in a test sealed box, and another on OB.
Fun driver, lively, yet controlled. Good details.
I prefer the sound coming from the OB, it feels like the driver is free to do its thing, while the sealed box sounds a little stuffed.
I have yet to make measurements.
