What about Monacor ku-516?

[andrew_87]

Hi diyer!


I'm very interesting in this kind of compression driver, expecially because they can go very low...


here is a link to the product:
MONACOR INTERNATIONAL:Pagina con particolari dei prodotti

here is a link to this forum where you can find some info on this driver (see also releated link):
http://www.diyaudio.com/forums/multi...drivers-4.html

but, to you know something else about this ku-516?

thank you!

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?

Any succes with the Monacor driver?
