Just heard my 8530k00 and 2905/9500 tweets sing for the first time. Wow! Just a first order crossover at this point.

Gringo....
What did you use for x-over?
I just picked up a pair of 15w/8530k-00 I'd like to try with first order x-over.

Just a 1mH coil in line with the 8530. 4.7 mF cap and 8.2ohm resistor and 4.7mF cap in line with the 2905/9500 tweeter. Polarity inverted on tweeter.
I know this is not a full range speaker. I mistakenly posted here first then on Multi-way where I took abuse for the minimalism of the post.

I have a second order crossover ready to go. I will hear it this weekend. It has a friendlier impedance curve for the amp.

Thanks. I'll try something similar with my DX25 tweeters.

Here is a complicated crossover for this pair and a good justification for it.

I am thinking about merging Paul Carmody's Carrera woofer x-over with his Amiga DX25 x-over. Probably have to increase the 5ohm resistor. Reason being, I have almost all the required coils and caps in the parts bin. At the moment I am waiting delivery of the woofers.
I also have a 2x4 minidsp to play with.

The 15w/8530k-00s arrived and I stuck them in 0.5 cu.ft cabinets with the LCR network that Paul C uses in his Carrera build. Running full range, they sound extraordinarily smooth and extended.
I have them toed-in to cross just in front of me. I am trying to decide if I need a tweeter?!
My ageing ears are limited to 10khz.
I'm thinking of building the 48" long mltl described earlier, folded and a height of 32"(WAF).

Any updates on projects with this driver? Despite my simulation looking flat these sound too bright.

Default Mltl

I did build a pair of mltl cabinets and used xt25 tweeters with the 15W woofers.
Picture attached. The crossovers are similar to those used in the ElamXT.
The enclosures are 32 high and work beautifully in my smallish music room.
