That's a MID CD (160-6500Hz). There are a few implementations that you can do with a Mid-CD from this and other manufacturers. One is a Visaton here (The mid-range horn with the DK 8 P 100 V/15 W horn speaker) Visaton - Lautsprecher und Zubehör, Loudspeakers and Accessories

Another one is the Selenium D250-X 1" Phenolic Horn Driver 1-3/8"-18 TPI here Parts-Express.com: Selenium D250-X 1" Phenolic Horn Driver 1-3/8"-18 TPI | compression driver tweeter horn driver high frequency 1" exit 1" throat midrange PA driver tweeter driver selenium083108

from my point of view CD mids are very interesting...
I read that the ku-516 could be crossed at 300hz, i suppose 12dB/oct, but how power can handle?
I also read that must be crosse at 1200-1500hz (higher limit) in order to avoid some hardness...

Do you agree? Do you ever heard this CD?

Thank you!
🙂

They are interesting and they are used many times in Bull Horns too.
You can look (more brands) at the (old) RCF's ("D" reference letter) D-3045 or D-5076/16Ohm (N/ND for compression Drivers) and EV-1823 EV-1824 Midrange Drivers. Like the ones from Monacor and Pyle capable of very high SPLs you can design a very powerful speaker adding a CD Tweeter or supertweeter. Compression drivers are easily damaged at low frequencies. The 1823 can go low to the 200Hz with AR/FR 150 Horn (180/8kHz) with power handl./Sine Waves of 90 watts. So in your case I would model the CD and check what it could deliver with adequate xover in conjunction, so having the resonance out of the way. Curves of measurements/complete specifications are also very helpful in this situations so that we know what to expect as is the case with good drivers for modeling.

thank you for the info.

I can find monacor components for a good price, so i will probably try this CD.

I would use it for PRO appliation:
- bass cabs: folded horn cabs 50-500hz
- mid CD: 500-1500hz
- high CD: 1500-20000hz

if possible i would like to increase the highest crossover frequency (1500hz) but I don't know if there are accettable hardness over 1500hz...

in order to handle enought power at 500hz i will build a 300hz horn (4phi design).

What do you think about that?

Hello everybody!
Please, I need help!
I am a beginner DIY and I want to build loudspeakers with Celestion Trovox 1525, RCF D-5076 and Horn Twitter. Crossover Freq ca. 300Hz and up to 5kHz.
Box for 1525 is ready and tested. It remains to find drivers and horns for MF and HF.
Who would have opinions about this?
Thank You all so much for the help!
With respect,
Vladi

Lose the midrange part and build a 2 way with a HF compression
driver and a XO frequency around 1000 Hz. Pick a 1" driver so your
high frequencies are not rolled off to soon. A higher quality horn
is worth the investment. Check the threads on the horn/waveguides.

An expert on horns is our member Dr.Geddes aka gedlee.
There is others, of course.
Google the horns by Auto tech.
Good luck.
