What I have in mind is what balerit suggested in post #2, different speakers.

Am I opposed to 31 band EQ? Not in the slightest. I have been in pro audio for 40+ years. A system is naked without one, or an equivalent. I just disagreed with the premise in the OP. If his speaks sounded bad in a room, were boomy or had a dip, sure correct with the EQ. When you are trying to get the sound of a 2x15 cab from a 10" speaker, then I don't think the graphic is the tool to use.

That is how I read his post. You may have read it and got a different idea. Perhaps indeed he is only curing a dip. Then fine. Right or wrong, I got the impression of a novice approach to insufficient speakers. All my arguments are made with that opremise in mind.

Sofa, I respect your knowledge, and I mean no disrespect, but I am going to stop arguing this point as I don't think we are advancing the thread now.

if you need to cut or boost a frequency 12 db there´s something very wrong with your speakers or system

No, no disrespect intended from me either. I don't prescribe every differing point of view as an argument.

I have an audiosource eq100. I bought it at a pawn shop for maybe $20-50. I tuned it using pink noise and took pains not to be too drastic with the controls and I did not try to get flat high or low frequencies, and I tried to balance the controls so that the level was approximately equal whether the eq was enabled or not. I found that the sound was fatiguing with the eq enabled. It adds a 'graininess' to the sound. I have found this with other EQ's in the past as well.

In the end they add enough noise and weirdness that I prefer leaving them out of circuit.

Don't forget you have to use a 10 band VU meter in conjunction with the equalizer and pink noise generator.

Default Cause over effect

Thanks all, okay, I will stay away from the equalizer, and keep my chips to resolve the cause, otherwise I am trying to at best, and dubiously at that to dope the effect, the lack of bass from the floorstanders. So I will remake the speakers.
I have purchased a David Weems book Designing, Building and Testing Your Own Speakers; written in very tangible insights for the novice, on the design and building aspects. When finished I will take them to a speaker technician for the electronics side. Thanks to all
