Behringer BFD - can you compensate for no subsonic filter? (1 Viewer)

[John*S]

Is it possible to use one of the bands on the Behringer to act as a pseudo sub-sonic filter?

How low a frequency can the bands on a BFD work?

Probably not very well, John. I think the lowest frequency setting on the BFD is 20Hz. If you set too wide a bandwidth you will get into the critical frequencies. Too narrow and all you have is a notch; everything below it will still be there.

A subsonic filter should be shelving. Some parametrics will let you do this (like the Ashly models), but not the BFD.

You might try experimenting with the bandwidth setting using a test disc and SPL meter to measure the effects. Maybe you can make it work, depending on your sub.

Thanks Wayne,

I've seen a lot of your posts. I don't have a BFD but was considering one.

The ART 351 has high and low pass filters, but of course that is a graphic EQ, with only 7 or so bands usable in the bass range.

Even if all you used it for was some gentle EQ'ing and the subsonic filter, it might be worth the $150 to you.
