hi
I would go for the cd10 over the cp25 personally
if your not set on beyma then also look at B&C DE12 from 2.2hz up around the same price as the cd10 and very sweet comp driver
also BMS 4524 another option

Hello Guys!

I'd like to build a pair of mid-top cabinets 120Hz and up.
I have two Beyma 10M250 drivers and im looking for a budget compression driver that would pair nice with the 10M250.

I was looking at the cd10Fe, crossing them around 2k-2,5k, but i fear that it will do poor at the real high frequencies.

My other choice would be the Beyma CP-25.
I saw cabinets built with them (Dare Audio Micro-10, the old ones), but i never heard one.

I dont know which would be the better choice.

Please help if you have any experience with them!

I prefer them a little higher myself, but it does depend how hard you drive them. At low power levels 1k6 - 2k is fine, at higher power levels I find it a little abrasive and need to crossover a bit higher.

Cross them at 1K5 at the moment, sounds sweet!

I love them. And yes if you do close listening with same material AND SAME SLOPE you can tell that 1.4 is no good and 1.6 is. Well I can. Straw camels back, blah
I have CDX1745 at moment, crossed 2.2k, they are sweet but the Beyma seems to have that, "big boy" sound rather than just being a tweeter.

For the price, the CD10Fe is an excellent comp driver, and yes I agree, needs very little EQ to sound nice.

I'm not aware of another driver at the same price point that beats the CD10Fe.

Sorry to bump a old topic, 

Because of a faulty amp I blew my BMS 4544 drivers, and needed a very quick replacement...
The Bms drivers are not readily available to me, and the cd10fe were on stock and very reasonably priced.
Must say, I was pleasantly surprised by the sound quality!

They don't suffer from the nasty 3K peak that the BMS drivers have, and needed very little EQ to sound nice. 
Top ''budget'' drivers for the money!
The BMS drivers will get a recone but the beyma drivers stay where they are!

It depends on the compression driver, and personal preference. I have tried the same compression driver, and just 200-300 hz shift in x-over point makes quite a big difference. It will depend on your program material, I find the issues with low x-over points most noticeable in powerful female vocals - if you are just playing dance music, there often isnt a great deal of program material in that range of any consequence, so you probably wouldnt notice.
 
But in terms of what's significant, I would say a frequency shift of 5-10% can be audible and significant.  A shift of 1% is not really significant. All components, horn and cabinets can have resonant frequencies, hot spots and variations in distortion levels, crossing over before you reach any nasty bits can make a big difference. The closer you get to the nasty bit, the more of it you hear.
 
In an ideal world components wouldnt have nasty bits, but sadly they do.

Some people like the harshness from the bottom end of the range of a compression driver, some dont.

I have to wonder how a driver can be brilliant crossed over at 1k6 and not good at 1k4, as the difference is so tiny as to be negligible. What matters more, I think, is the crossover slope. If Beyma says that the driver can cross over at 1.2kHz I'd be inclined to believe them, although I've not tried it personally. It certainly looks good for the money. The distortion curves and waterfall plots will reveal all, however.

I *have* tried the Celestion CDX-1731 compression driver which Celestion recommend crossing over at 2.2kHz, and that is fine crossed over at 1.2K with a steep x-over.

Very nice driver for the money at 1k6. Brilliant replacement in the cheap JBL JRX stuff. Tried at 1k4 on some 2x15's and you could hear the beginnings of trouble. 1k6 sweet.
 Some of those BMS need some serious EQ to get nice IIRC. Had some off the late Tony and moaned, he sent LMS settings and all was good, can't remember model. So maybe not good for passive cabs all the time?

Agreed, HF146 is much nicer, but then you are in the price bracket of quite a number of 1.4" compression drivers and have a fair choice if you are willing to spend that.
