In another thread, Thomas wrote: I've owned the Behringer DSP1100. I currently own a DSP1124P, a FBQ2496, a DEQ2496 and a pair of Symetrix 551 analog parametric EQ's. When Eqing a sub I'm at a loss to hear an audible difference between any of these. There's an obvious difference when EQing my main speakers. Which is your favorite for EQ'ing your mains? Are you running the eq between a digital source and your DAC? Do the benefits outweigh the negatives? I just EQ's my subs with a DSP1124P, and the results are so good that I'm interested in EQing the rest of the system. That and Room EQ Wizard showed me how uneven the mains are. |

That's a very nice looking speaker!
While you don't EQ your mains now, according to the quote above, you did try it out, maybe with different speakers, and you said that there were clear differences between the various eq's listed. I'm simply interested in your thoughts on the eq's mentioned for eq'ing someone's mains who doesn't have nearly as nice of speakers as you do.

I've played with the Symetrix on the mains in my family room (different speakers) . I wouldn't consider using either the DSP1124P or the FBQ2496 on mains since they were never intended to be used as equalizers, they're designed to cut micophone squeal.
The Symetrix (discontinued) and the Rane PE17 are analog parametics EQ's. Sound good, VERY difficult to set since they use little knobs not digital readouts. This means they can't be accurately set without test equipment.
I have the components on the way to make more balanced cables. When those are here, I'm going to play around the the DEQ2496 on the family room mains (probably 10 days-2 weeks away)

Thanks Thomas. I look forward to what you find out. I was thinking of trying the DEQ2496, but it'll have to wait awhile.

The black panels are Acoustat 1+1's, there's a line array of 16 Techinc H400 leaf tweeters. That's an older pic, the current incarnation has a B&G RD-75 as midrange.

I've done some reading on this, and I found many people came to the same conclusions when they tried this. While one can make the speaker's curve look better graphically, it takes the life out of the sound.
Any thoughts on this?

Mains don't have the same kind of room interaction problems as subs. But they're more revealing of the quality of the electronics in the signal path. So cheap EQs aren't a good idea for the main speakers.
Perfectly 'flat' FR is perceived by some as un-involving since they're accustomed to peaky sound.
IMO for mains the first line of attack should be proper room placement and acoustic treatments. Then EQ can be used to fine-tune if needed/wanted.

Agree that most EQ's are not enhancing to the sound of the mains.
However, if using a really good processor, then it really makes a positive difference.
My Martin Logans are extremely revealing, and I found that the PEQ in the DBX DriveRack 260 I use for Crossovers is quite clean.
But I caution against setting this stuff 'by ear', results will not be good. I use ETF and spend hours calibrating.

My Denon receiver does EQ on the whole of the system with the exception of the bass. So my other 7 speakers get EQ to my listening position. Works great.

The thing that people tend to forget is that EQing for one fixed spot in the room is a fools errand unless only one person sits in the room.
Mapping the room then using an average is the best way to EQ all the listening positions.
The 'demo room' information from the ETF website is a great tutorial regarding the correct use of EQ.

Fortunately my wife has tin ears, she cannot even identify sour notes the singers on American Idol regularly belt out. So I EQ for my postion and she gets whatever her position gives. She prefers to sit way off to the side of the room anyway.
I don't use the flat, or all same as front, I use the normal which is better to my ears. I have EQed many years ago in accordance with some guys assessment of psycho acoustics. I had an EQ with self calibration. Would set it all flat then adjust according to the psycho acoustic curve that seemed best for my ears and brain. The Normal setting on the Denon seems about the same as that.
