Re: EQ'ing of main speaker bass drivers?


Hi bob

450 hz is rather high perhaps for the bfd, and according to all reports may not be clean enough up there (never experienced on myself).

Not really sure what PAMP is...Power AMP??

Personally, I would be very comfortable in using the DEQ in this situation, it is considerably more expensive than the BFD but to my ears does sound pretty clean and carries a heck of a lot more power.

I was going to do some test's on it earlier, indeed Wayne suggested what type of test's I could run on it for everyone, don't recall where to find his suggestions now!!

Wiyhout fully understanding your setup yet, I would put it between the pre and the bass amp and imply integrate it by using REW sweeps.

As Wayne mentioned though, perhaps the only sticking point could be that all the processing is done in the digital domain, so would have extra ad/da conversions in the bass only, which may even introduce some sort of processing delay between the bass and mid/highs, which nay not be ideal.

The only alternative to that might be to run the entire signal thru the unit (digital in), avoiding a un-needed extra conversion and controlling the bass response that way.

I perhaps wouldn't put this unit on a $6000 pair of speakers, but feel reasonably confident that the gains on anything else would outweigh the negatives.

If I can answer any questions I would be glad to,assuming of course that you may want to investigate further.
