I bought a pair too. Still sitting in the box while I finish other designs in progress. That large face plate (4.53") has me thinking 8" woofers.
I'm not sure it would work out well for a 2-way: F3 of 77 Hz in vented 1 ft3 (per PE) and 2.3 mm Xmax. Plus, due to its size, it would be hard to mate with a tweeter that can go low enough so you don't end up with a dispersion mis-match at the crossover. Perhaps a robust tweeter in a large waveguide (e.g. SEOS-10 or SEOS-12) plus a sub or two for the low end. That would certainly give you a high efficiency system. Or as a mid in a 3-way.
That driver is designed for exactly that alignment (with an aggressive low cut filter) to serve as an anchor to an affordable stage monitor, or possibly even as part of a top sitting on a 15-18" bass bin. Pair it with a compression driver and 12" horn, and a XO of 1000hz is easy enough. I wouldn't personally try to fit it into a home HiFi application.

My pair of DX25BG60 register at a Zmax of about 20 ohms, so this tells me the Tymphany/Peerless to not have F/F.
That's interesting! The spec sheet from Tymphany shows aomething like 14 ohms, and yes I got the idea it had FF from the very suppressed looking Z curve shape. So I was wrong!

Madisound is a great company to deal with. I always get my standard shipped packages the next day. Too bad they don't offer free shipping like PE.
Now what would be a good quality low cost woofer 6-8" woofer in the 40-60$ range for this tweeter? no frills but gets the work done without any objection? something that's better than the RS line and widely available....
IMO in that price range, there is not a lot of variability in driver quality. Take your pick of 6-8" woofers and run with it.
The Tymphany will cross fairly low, so 8" is likely a possibility. I guess I would give the Peerless mentioned a try, or 8" aluminum designer from Dayton.
In the 6-7" range, there are even fewer drivers that standout on cost/performance ratio in this price range. A safe bet is SB, but the Seas Prestige is an overlooked driver in the DIY world that sounds just fine.

Waiting on @Gowa to snag more 8¾" Rivals.
What do you guys think about this deal? I don't have time to model it today, but looks promising for a high efficiency TM or TMM.

OB mid?
Yeah, it probably would have worked for that (high Qts) , but I do not have the proper room for an OB setup.

Sweet! Thanks JR. Ordered 10 @ 21.60.
What ya got planned for em?
I'd love to see an honest, blind listening comparison between that Tymphany and this ScanSpeak: https://madisoundspeakerstore.com/scanspeak-soft-dome-tweeters/scanspeak-discovery-d2604/833000-1-dome-tweeter/
Clearly two versions of the same overall design, one has FF, one does not, one has a superior xmax (and lower sensitivity), etc. etc.
That would be interesting. Fs is actually lower on the Vifa?
Forget about the opinions of blind people, send one of each to Erin and get some real data!

I use them to much. For under $10 and it’s frame size It’s a great driver.
So is the SDS 4" there...

My pair of DX25BG60 register at a Zmax of about 20 ohms, so this tells me the Tymphany/Peerless to not have F/F.

What’s F/F ?

Maybe not. This is on the Madisound page JR linked above.
It is not my experience that tweeters with F/F have Zmax as high as 20 ohms, but I suppose it is possible.
