Hi terry,

Thanks for your response. It sounds like you've had some success with the device overall.

I also have a gut feeling that the DEQ might have a cleaner sound to it, but I'm not sure why I feel that way. It may be hard to tell when EQing sub levels only. I did use a peaky gain filter the other day, and there was terrible audible ringing, even though my sub measured flat. I forgot to look at the waterfall plot; it would probably have shown what I was hearing. It wasn't subtle; it was bad. So I wonder if these two devices implemented different types of digital filters such that they would have a different sound. I guess I may end up being the guy to try to rate the differences between the two.

I think you're right about the shelf filter being a little shallow, and also correct that you can make a resonable cutoff by using it in conjunction with the GEQ and/or PEQ.

Yeah, the Vandersteens are probably revealing enough so that I wouldn't want to try to EQ them. Of course, once I get the DEQ in place and everything running, there would be no harm in doing a test to see if it improves things over the full frequency spectrum.

No tests in mind at the moment, but if you come up with any ideas, go for it!

Guess that's it! Time for work...
