Cheap CD Experiments

Hello everyone,

I've recently been in contact with a Chinese supplier of horn and other goodies.

I've managed to convince them to send me free samples (see pictures 1 and 2).
They do have a wide variety of horns (at least 150 different models).

Most of it seems to be unbranded JBL Pro stuff.
Dimensions are formatted this way:
w*h*l all units are mm

Big horn:
370 x 190 x 165

Front:

Top:

Back

Small horn:
200 x 95 x 80

Now the question is, what cheap CD would you advise using with horns like these? It'll run active with a Minidsp 2x4 HD.
I've been looking at a couple of different drivers myself, including:

Celestion CDX1-1748.
Build-in 1" 3/8 threading. Very smooth response. Minimum crossover at 1600hz.

.Kartesian Cmp35_vPA
Smooth response. "new driver"?. I haven't seen it mentioned much.

RCF ND350
falling response towards the treble area, 2. order HPF would probably smooth it enough?

What else could you recommend me to try out?
My budget is 100-150€. I will document my findings using a Umik-1 in the future.
 
What type of flare expansion is used on those horns? Did they provide their own measurements?

Not sure if you want my honest opinion but those horns have long parallel walls at the throat and crude details... You should look for something more modern unless their is a specific reason for choosing these, such as loading capability for lower crossover etc

I don't have any idea at all. The info provided to me was a picture and the dimensions. In typical Alibaba fashion, they didn't have any measurements either.
What caught my attention about these was the horn walls, which resemble the newer JBL horn style by the way the horn walls curve inwards.
My plan with the small horn -provided that I could get it to work, was a poor man's version of a jbl 4306

What kind of horn, big or small, would you recommend?
Luckily I got these for free minus shipping
