To BFD or not to BFD


Been thinking about EQing tonight and looking at various options.

FEEDBACK DESTROYER PRO DSP1124P - £70 approx

FEEDBACK DESTROYER PRO FBQ2496 - £120 approx

ULTRADRIVE PRO DCX2496 £220

ANTI MODE 8033 - £240

The first one seems to quite popular but am worried about the frequency response only starting at 20hz. What about frequencies below this as I am sure mine will hit a bit below that. How does that get measured. The second one has an auto facility on it from what I have read which would be handle with the option of manually tuning it. The third has a frequency response starting at 10hz and the Anti mode is 16hz. Does all this really make much difference.

Opinions would be appreciated please.

cheers
Graham

Re: To BFD or not to BFD



Hi Graham,

The BFD operates well below 20 Hz. It's just the lowest frequency that you can set a filter for.

The Ultradrive is primarily a speaker controlling processor that has equalization along with crossovers and other features. For the most part it's way overkill for subwoofers

Unless you need to kill a peak below 20 Hz, the BFD is your best bet.

Regards,
Wayne

Re: To BFD or not to BFD


I'm using the UltraDrive and it is top notch...very flexible...and on top of doing EQ duty, you can also use it for crossover, dynamic eq, etc etc....it's worth the extra money!

Re: To BFD or not to BFD


Is there anything that the BFD does for EQ'ing subs better than the DCX ?

Im looking at EQ'ing my new subs for both HT and HIFI use and im currently researching my options. If the DCX can do everything the BFD does, then Ill most likely just get one of those.

Not that I'm aware of. It doesn't come close to the features on a DCX, but it does EQ subs at an inexpensive price.

cheers.

I figure if the DCX does what the BFD can do, then i might be worth the extra dollars as it could be later used for a more complex task if the need arises. Whereas the BFD is really only for one thing from what I can tell.

Re: To BFD or not to BFD


It might be useful Graham considering an EQ device which also works in the time domain as decay times or what some call ringing can still be bad even when a response looks flat, I believe the Anitmode also works in the time domain and seems to do a very good job or else you have the more expensive option which is the SVS EQ1...

Re: To BFD or not to BFD


All the Behringer equalizers use IIR filters that counter room modes in the time domain.
