So this would be the idea (some EQ is needed anyway). Especially suitable for drivers with large exit angles.
(Right now I'm looking at FANE CD131 1" driver - seems like a nice candidate.)

Hi again,
I have spent some time off-line (a blessing in itself...). What i mean by donating is just that, donating. These mics are "left overs" from my former employer and i grabbed them before they where thrown in bin! I can spare six of them for a good cause but if you plan on putting more than 6 in an array it might not be the best way forward for you.
On top of the mics you will need something to drive them (ICP amps) and that will of course add to the cost, nothing very expensive or complicated but still needed. They have been used for acoustic testing in mass production of mobile devices with the main interface beeing a PC with an NI NIDAQ pci card and various SW solutions.
Let me know if you are interested.
BR,
Anders
No need to get carried away, the Sica will crush every Bliesma tweeter as far as SPL is concerned.
An externally hosted image should be here but it was not working when we last tested it.
Can't comment on the Bliesmas (bet they are among the best dome tweets), but I know I prefer the sound of the Sica's PEI diaphragm to most metal diaphragms.

For example, this should be possible with BMS 4554 (note that the throat impedance is referenced to ⌀17 mm, which would be the actual throat diameter in this case).

Thanks for the offer, I'll have to think about it - frankly I don't want to mess with another electronics and I'd like to stay at the DIY level regarding the costs. At the moment I'm able to use my old trusted E-MU Tracker Pre which has quite nice stereo input for pre-polarised electrets. If that shows to be insufficient, I'll just let it go...
BTW, the electret capsules arrived from Texas yesterday 🙂
Thanks - but this was more aimed at mabat and the horn that was 3D printed... where there any listening impressions?

Very impressive that you can come up with and idea and then simulate it and all! Hopefully the industry sees your work and all future horns and drivers will be perfect 🙂 These simulations and ability to iterate variations is very valuable, demystifies horn design a lot. 99% all commercial horns seem like shot from the hip when comparing to the data presented in this thread.
I was wondering if there was any listening impressions of the horn made by the 3D printer (grey, taped and in 3 parts)?

1,5 - 2 kHz without any problem, IMO. This would be for small home speakers.
- It has also a bit wider coverage than typical to be well usable even with 7" midwoofers.

Nothing special, really. After making some proper designs with waveguides, it's just routine. The sensitivity is still there to spare.
