hi,
i have four faitalpro 12fh500 (500rms each, 97dbspl) acting midrange. i need two compression drivers to keep up with my mid drivers.
first i thought i would go for two used gs audio tw-75: https://audio55.se/sv/products/tw-75
but then i thought i maybe should go for something that actually would sound okay, instead of just being very loud (which is what i am aiming for btw)
what are your sugestions on a loud compression driver that can keep up with a pair of 12fh500? i am on a budget

as far as i understand, not all horns fit all drivers.
but okay, fair enough, i am looking for a driver/horn combo

what will you do with these speakers and where will you do it? you must choose a horn by cutoff frequency, dispersion pattern, coverage angle, driver exit size, etc. if you tell us the application we can suggest horn/driver combos.

i will put them on a truck bed like this:
there will be people watching from the streets, but it will be people on the truck bed too

you want a single stack with arrayed tops like in the photo, or L+R stacks with one horn per side? will you be building the cabinets?
yes i will be building the cabinets.
it will be a single stack. i was thinking i would do two 2*12" tops, but i could as well just build a single 4*12" box and then a box only for the tweeters. that way it would be less cables to connect, because i will run horns on a separate channel and use DSP, instead of building an XO

I would look for a constant directivity horn with a 60 degree horizontal pattern. Both of these are very nice:

You will mate them with a 1.4" compression driver. I don't have a "budget" suggestion off the top of my head. Faital HF146 would be a good choice though. I like polymer diaphragms as opposed to titanium, they sound smoother to me, especially at high volume. You will definitely want DSP to EQ any horn/driver combo. Also, this horn/driver combo isn't inexpensive. But this is the frequency range that makes the difference between pleasure and pain in a high SPL system.
You'll want to pay attention to the directivity of the woofers as they cross over to the horn. Ideally the patterns match at the XO. Usually a 15" is used with a 1.4" CD + 60deg horn with a 1kHz cross. The larger woofer becomes more directive as the frequency increases towards the crossover. A 12" will be somewhat wider dispersion than the horn. A quad array of 12" might be OK here too but would err on the other side of being too narrowly directive, with comb filtering as well. Whatever you do keep the distance between the mids and horn as small as possible. Up to you if you want to pursue this design rabbit hole, many dance stack designers don't seem to be too concerned ;-) You could investigate placing the woofers in a V-shaped baffle to better control their dispersion.
You don't want the horizontal horn patterns to overlap and cause interference, so build "trap" cabinets with a 60 degree splay. A listener will mostly only hear one HF source at a time and you will cover a 120 degree wide area. Also think about the vertical aim of the horns, many stacks put the HF up high and pointed straight ahead, wasting most of the horn's output as it flies over everyones' heads. Try to angle the horn down at the audience if possible (yes this makes construction even more difficult.)
I wonder if anyone has a link to proven designs that would work here...
