You are not messing with it. It is the room that already messed with it. Correcting low frequency response with acoustic material alone is darn near impossible and even if you got there, you risk creating a very dead/dull room. EQ when applied to minimum phase response of the system completely reverses this distortion. It is not at all messing with it.
This has been tested formally of course. From AES paper by Sean Olive:
"Room correction, when done properly, can
provide significant improvements in the sound
quality of loudspeakers in rooms. Three of the
five room corrections produced significantly
higher preference ratings than the uncorrected
loudspeaker/subwoofer.
[...]
Listener comments and spectral balance ratings
indicate the more preferred room corrections
sound more neutral, less colored, with more
ideal spectral balances."

Unless you tell me all of a sudden we don't value what we hear and those terms that describe it, what you are saying simply is not correct. If you have an ordinary room and have no EQ, I guarantee your bass is colored and can be improved.
I'm going to put an unadulterated plug for myself here; you're partially correct 853guy in your assessment regarding some vintage components but that's only part of it, setup is the other half of the equation. You can change, make or break a system through setup as much as through the components, if not more. When I visited Steve the only thing we worked on aside from setting up his table was his setup and that's how his sound changed from what it was towards "Natural" transforming his listening experience and not changing the system. He continues to improve his sound by himself; more "Natural", by tweaking the setup more than we had time for.

No, I am trying to do my best to avoid it . Your question hugely increases the topic of discussion and the last thread we on that made a bunch of people super upset. Here, our main business is to keep digging into the meaning of the word "natural."Amir: would you care to address the question i put to you and Tom in the first paragraph of #304 (which I reposted in #328)?
No, you can do serious damage with room EQ. Not all of them are created equally. You would have to do careful AB testing to make sure it gives subjective improvement. The ear is critical in that. Unfortunately mass market EQ systems don't make that easy or possible and without it, I usually turn them off.Separate from that, you seem to be saying that any sonic artifacts imposed by the electronics in digital room correction are of less significance than the result in measured performance, as validated by listener polling or studies (or alternatively, that there are no such sonic artifacts, based on measurements and listener polling).
I sympathize with that. I can appreciate that someone who avoids digital systems would not want to stick an ADC and DAC in the path especially in midrange. I respect the choice to avoid DSP in that regard.I know Avantgarde, who make the horn system I use, has now gone to digital room correction and electronic crossovers for their latest line of products, which I have not heard. My (older) Avantgarde (Duo) has no Xover whatsoever between the amp and midrange horn, which runs its full range. (The other drivers do have crossovers, including an active woofer system which I have always found tricky to blend with the character of the horns- there I could see some value in room correction, but I'd be loathe to mess with the midrange to use David's parlance).

I will stop here and note what a rich discussion we had about the "sound" of your system by providing just one graph to us. A lot was conveyed and feedback given to potentially improve the system performance. No subjective accolade of "great harmonic structure, natural sound, fantastic microdynamics" would have gotten us anything whatsoever. This is why I say might as well throw all of those pretend terms out the window and just say you heard great music reproduction. Let's not provide technical terms that at the end of the day are not actionable in any way.
Thank-you, thoughtful and sympathetic to my views, which are always being refined, in part by what I learn from others.No, I am trying to do my best to avoid it . Your question hugely increases the topic of discussion and the last thread we on that made a bunch of people super upset.

I will say one thing though: I care next to nothing about correctness of time. If that is important in loudspeakers, the designer needs to have dealt with it. I am not going to use DSP to change that.

My ask is to consider it for bass region where it does most good and any artifacts are simply inaudible compared to the good it can do.

One can only wonder is it the use of the term natural that is bothersome or the system it was appllied to that is so provocative,
We have an entire thread where we took the position that "natural" is a lay term that has little insight coming with it. Now you are saying I have to accept that descriptor to have a meaning??? It has no meaning. I don't know what it means to have natural bass in your mind. I do know what is correct bass when I create it and a bunch of people in a listening test give it thumbs up. And I can correlate that with measurements of the same. Naturally , remedies fall out of that, i.e. correcting the response.- This is a separate matter, I'm not arguing that better in room bass response isn't desirable but that end result of digital EQ won't sound "Natural". Here's what I said;
"IME digital EQ is the furthest thing from "Natural" as argued by us here. Eq'ing a system has nothing to do with the room, you're only messing around with the system's frequency response"
- "Room correction, when done properly……" Room correction is a misnomer to begin and none of this article is relevant to my comment on digital EQ in reference to "Natural" sound.
- Dampening is but one way, there are other methods to change the room's qualities, I agree that the end result shouldn't be dead.
- There's no point in arguing in circles, for example you look at an ordinary room differently that I do. For me an ordinary room means fewer issues and is a good thing. We both accept that good bass response is important but we have different methods for getting it because our end value and definition for better isn't the same. What I've defined as better i.e., "Natural" IMO can't be achieved with digital EQ. You should understand and accept my "Natural" first then show me where I'm wrong, but don't ignore it.

Yep, and if we are talking about the same speaker, that one hasn't gone to the digital X over, room correction versions yet. I think those speakers are effectively the end of the line for that model.The new Avantegarde Duo Mezzo is a massive improvement over their previous model imo. In the past I'd never consider AG but the Duo Mezzo is compelling.

Natural as a term of enjoyment or good feeling about a system doesn't yield any analysis or response.
Ok, here's a question to all: One of my friends the other day said to me; "Bob, I like my women au naturel".
What did he mean by that..."au naturel" ?
* And please, don't draw any comparison of naturel women with "natural sound", ...just don't.
...Now go ahead, give it your best shot. :b
