Horn loaded dome tweeter 500-20 khz?

[Defo]

Is there any dome tweeters around that can work from 500 hz and up in a big enough horn? I've looked at these:

Scan-Speak Discovery D2604/833000, 1" Dome Tweeter from Madisound

Scan-Speak Illuminator D3004/602010 Tweeter, deep chamber from Madisound

SB Acoustics SB29RDCN-C000-4 Neo Magnet, Ring Dome from Madisound

Any thoughts?

I already have a large spherical horn for it The reason I'm playing with the thought of using a dome is that I havent found any compression drivers without a metal diaphragm (which sounds harsh) that can be used down to 500 hz.

I would love to have the softness of a dome, with the dynamics of horns.

Here's a thought.

Get a small (2") wide range driver. Surely, something like that would be more suitable to go as low as you require...

Problem is too low sensitivity and no natural roll of around horn cf which complicates crossover.

You have many CDs that are good for mid drivers work ("2” (50 mm) exit compression driver for high sensitivity, low distortion and smooth medium frequency response applications") from 500Hz and lower.

Also interesting (for tests, low SPL?/91dB) and never considered is the

Titanium diaphragm = harsh to my ears

but comp.drivers is offtopic
what about (linear) excursion of dome tweeter at 500 Hz?

Cool driver, but I don't want to go 3-way

Linear excursion should be low at 500 hz due to the horn. But I'm no expert, so it would be great to hear some thoughts/experiences.
