I'm considering building a U12, designs available from B&C, with the dedicated passive crossover FBU128.
Now I'm not a fan of Titanium diaphragms and would like to replace the suggested DE780 compression driver with something else.
AudioXpress tested the driver and you can see 3.66ms long streaks in the waterfall plot around 14kHz - that won't work for my taste.
Now my question is, can I still utilize the FBU128 crossover when using another compression driver under certain considerations?
For example I'm looking at a Beyma CD14ND.
Obviously this driver would have to have the same impedance as the DE780. But when I look at both the DE780 and CD14ND impedance curves, they differ naturally along different frequencies. Or any driver for that matter. If at all, how much of an effect can this have on the end result of a targeted flat response? Also, does the power rating of the driver have an effect as well, other than me having to rebalance the outputs of the two drivers in the box.
I'm going to use a nice Pro amplifier with quite some DSPing available.
I'm also open to suggestions for other compression drivers (budget is up to $250). Also considering BMS 4554 (even though crossover to high for this one probably) , FaitalPro HF146,...
I'm a bit new to passive xovers, so far I used actives only. I hope my questions are not too naive.
Thanks!
