Passive Crossover Specs, What frequency? was created by joshworthy
Hi,
I've just ordered a pair of Eminence Delta 12 and a pair of Beyma CD10Fe 1" 8 ohm 70W Compression Drivers.
I'm building some single 12" dirver versions of the SMT 212 (SMT112 if you will...)
I'd like to have a crack at buiding my owen passive x-overs for the cabs but I'm not sure where to cross them... I was thinking 3KHz but maybe this is too high?
I'm also wondering how much I need to attenuate the comp driver ? Do I calculate from sensitivity 109db vs 98db?
Or is it better to Biamp and active x over the comp and 12" separately? I'm looking to pick up a dbx drive rack soon and I hope that this will handle it.
Regards,
JOsh.

Looking at the specs for the Beyma i be looking for a crossover at 1.2 to 1.5k. You will need to keep your 12s at a 9.04 ins center to center.

I ended up going with these 3K ones as I was In a bit of a rush to get the project finished for a party in July.

I initially found that they sounded a bit shrill and put it down to comp driver being more sensitive that the 12. I ended up getting a driverack 260 and EQing seemed to smooth it out
