Kii Three have the purifi amp now

I haven’t really found that a quality compression driver ( Cessaro used TAD drivers almost exclusively ) to sound more open or more detailed, more coloured yes.
And though I assume someone might disagree with this, I don't believe internal electronics we have today are truly transparent sounding either. It's quite easy to hear the difference between the Hypex DLCP and a better DSP/DAC.
I can offer the speaker with a compression driver with aluminum diaphragm instead of beryllium as well. This brings down the cost substantially. The compression driver I'm using also sounds very open, clear and detailed with aluminum diaphragm.I haven’t really found that a quality compression driver ( Cessaro used TAD drivers almost exclusively ) to sound more open or more detailed, more coloured yes.
The Danleys did sound very clear, but I assumed that was more to do with their narrow directionality.
One of the reasons I find your designs interesting.

so this only the mid-range horn?Vera Audio is developing a horn speaker system. It consist of a midrange horn, a midbass horn and requires a bass/subwoofer solution. It will be active and offered with a separate high quality DSP.
The 2-horn system look like the following:
I'll show some measurements of the midrange/top horn. With the driver we're using, it's able to cover the range from approximately 500/600 Hz and all the up to the highest frequencies.
The measurements of a prototype horn were conducted in a small gym with the ground plane method.
Due to size of the facility, the measuremen isn't anoechoic and we couldn't measure far enough away in order to get the beamwidth 100% correct. The horn has a likely a narrower directivity then what's seen in these measurements. New measurements under better conditions will be made later.
The horizontal directivity without any gating looked like this:
A gating with 24ms isn't sufficient to rule out all reflections as there were reflections arriving as early at 15ms at certain angles, but is shown below:
The horn was also measured vertically.
Vertical directivity with no gating:
Vertical directivity with 24ms gating:
Conclusion
The midrange horn measured with an extremely uniform directivity. Horizontally the directivity is text book apart from a small widening at 800-900 Hz. Vertically the polar is also very constant with some minor abberations. The horn is able to maintain direcitivity both high in frequency and very low in frequency which is unusual for speakers. How low exactly will require measurements in a more anechoic environment.

The speaker link gives an error for me
It's a 2-way horn that requires a separate bass solution/subwoofer.so this only the mid-range horn?
Ok, I see, but the picture for the measurements who only one. So they were measure one by one and then combined? what is the xover freq?It's a 2-way horn that requires a separate bass solution/subwoofer.
The 2-way horn looks like this:

Our subwoofer will get some aesthetic modifications, but prototype looked like this:

The subwoofer is a dual 18" design with horn loading in a small area.
The polars are measured separately. However, there's a measurement of both indoor over a reflective floor at different heights here:Ok, I see, but the picture for the measurements who only one. So they were measure one by one and then combined? what is the xover freq?
