BFD question (1 Viewer)

[Brian Dobbs]

Can the BFD cancel out any frequencies above a certain frequency? For instance, instead of using a crossover to cancel out high frequencies when running a full range signal to a subwoofer, can I use this device to deny any mid to high frequencies? I am trying to find a way to cancel out the high frequencies in a full range signal. thanks

IMHO, a BFD is not well-suited in function as a crossover or low-pass filter. You're better off getting a real crossover.

I don't think it would be possible. Even thought the BFD has 12 filters, more than enough for sub equalization which is what it is mostly used for in HT work, it would be impossible to attenuate everything above a certain frequency. There just wouldn't be enough filters. And I don't think they cut 100%, only a certain number of DB.
