beyma cd10fe

   This is one of the most common 'issues' with speaker design, finding a pair of components that work together to give the optimum sound, and more often that not there is a slightly compromise somewhere.
People often try crossover frequencies between 1.6k and 2.5k and test until they get the sound they are happy with. 

Depending on the 12" driver, you may find the response starts to drop off a little around 2k, if its a gentle roll off I wouldnt worry about it too much. To me a slight dip around 2k is preferable to honk and distortion. 

The CD10Fe is a nice compression driver, when I have used it I have preferred it crossed over around 2.5k, you can go lower but you may find it harsh on female vocals. 

The CD1014Fe is competitively priced for what it is, but it is just a CD10Fe with a wider exit. The diaphragm and voice coil are exactly the same as the CD10Fe so you are unlikely to get much different performance with that compared with the CD10Fe. 

If you like Beyma the CP755Ti is a really nice sounding compression driver, but the price reflects that, so may be out of your budget.

With a little bit of fine tuning, I'm sure you can get very acceptable results with 12" and 1". If you have an adjustable active crossover, try varying the frequency between around 1.6k and 2.2k until you get a sound you are happy with, and then go with that, wont be perfect, but like I said, you almost always have to have some compromise.

	Thanks Andy. I guess I will need to look at the beyma cd14fe then. This the the 12inch driver that's going below. Not sure if it will play well up to 2.2k. https://www.dropbox.com/s/ak7f74p3v762c9l/CELTO_12MB420_EDS_2014-04.pdf?dl=0 Edited by rish - 18 June 2016 at 2:52pm

	Many compression drivers that state a low minimum crossover frequency (1000-1200Hz is low for 1") will manage it, but usually with the maximum power handling having to be reduced 20-30%. Although they will do it, its not necessarily a good idea, most 1" comp drivers tend to honk and have high distortion at lower frequencies. I generally try to keep 1" crossover points above 2.2kHz Keep the comp driver well within it's maximum operating range and it will last longer and sound smoother. Your car can probably do 6-7,000 revs - doesn't mean its a good idea to driver around in 1st gear at 6,000 revs all the time, and it wont sound very nice...

	ive never crossed one over that low ,i think i did mine at 1.6/1.8 they might work that low but i dont know how that would effect the quality, if you have to cross that low on 1" driver then id look at bms 4550 not that much more meoney but deffinatly able to cross that low
	GOD TOLD ME TO DO IT !!!!!

	Hi Guys I am undertaking a small project and want to know if the beyma cd10fe will actually cross over at 1.2k as its state. Anyone had any experience with this driver? Rish
