Actually as I'm fond of saying on these fora the distance between speakers is more often that not considerably less than people think, you know, the conventional thinking goes something like in order to get a wider soundstage you have to place the speakers wider apart, right? And you have to tie them in a little too to aim them at you to improve the imaging, right? Well, actually not right. Start with the distance of 4 feet between the speakers and slowly work them out until you find the sweet spot. I kind of suspect this is especially true for small rooms. Lots of folks have small rooms and obtain terrific soundstage, perhaps even larger than the room dimensions. The room at the shows tend themselves to be on the small-medium size. I'm pretty sure you'll be quite surprised when you obtain the correct distance between the speakers. I also FREQUENTLY recommend the XLO test CD which really is the only fool proof way to set speakers up. Everything else is just guessing.

RoomTune :)

Don't have the tools, won't get the results!

Geoff:

I totally agree with your points; and also possess the digital files of the XLO test CD.

As for speaker separation, I did in fact start with them near 4' apart. However; mostly due to the unfortunate and very strong Bass preponderance that no amount of speaker positioning could remedy, as well as the fact I already have a main room luckily to fall back to, I dismissed my idea of a dedicated audio room; as nice as that sounded.

I do want to also clarify and echo with agreement that a "small" music room does not necessarily mean a "bad" music room. I think with the cathedral ceiling and just unfortunate acoustics, my particular smaller room presented immediately some serious challenges instead of what I had hoped to be an immediate improvement. Resulting again to just falling back to the main listening room.

Respectfully,

Ron

Yup, only so much one can do without a considerable amount of room acoustics stuff. Plus all the other stuff audiophiles are fond of. Takes a long time to get everything right. Everything is relative. It's difficult to know where the sound of our systems actually falls in the overall pecking order at the beginning and for quite some time, mainly because really good sounding systems are VERY FEW and FAR BETWEEN. I rate most systems - even really big systems - somewhere between unlistenable and pedestrian. I was an audio insider from the get go. It's a curse. Lol

Nah, it's not that hard lol. Just another part of the hobby to practice.

I look at RoomTuning from the positive side, maybe that's because of having more successful listening than un-successful. Last 30 some years it's a piece of cake, with once in a while finding a tough one to deal with. Main thing that makes it easy for me is doing so many of them. Now, I can get to that 3d sound pretty quick. it's all about becoming a listening master. One of my friends "Herns" is one of those guys that can knock tuning out of the park everytime. I love watching a master at work, and Hern's is one for sure. What a set of ears, and not only that but he is able to know which part of the audio-trilogy needs to be dealt with at what time, which is a big part of the art. System tuning is kinda like scaffolding. You make one side work and then pull up the other side, it gets higher, then you go back and keep inching your way up, seeing more of the landscape each time. If you get stuck sometimes, it a lot of times means you went too far in one direction and need to even things back out, and find where you lost part of the signal or just have it out of tune.

For myself it's like this fun video game I get to play each day. I get to tune mine and I get to work with others on theirs. Doesn't get much more fun than that.

Not that hard, and it only took you thirty years? Shirley, there must be a better way. Lol. I suspect a lot of audiophiles view themselves as listening masters and think their systems are the greatest. And that their hearing is the greatest. Especially those with thirty or forty years under their belts. And after, what, a hundred thousand bucks, at least? What audiophile would say his system sounds like crap? Answer later at 11.
My experience with room tuning, and I have a lot, if you recall I was one of your first customers, that it's like trying to solve two simultaneous equations in three unknowns - you can waste an enormous amount of time dicking around and never actually find the absolute best locations for room acoustic devices. Of course, I don't have that particular worry any more since Headphone listening completely eliminates the room from the equation. Hel-loo! But if you wish to continue to beat your head against the wall, please be my guest So, to summarize, tuning takes a long time, thirty years, to master, and it requires a certain shall we say lifestyle to master it. Kind of analogous to the lifestyle of owners of British sports cars who just LOVE fiddling with their cars. Again, experience! Lol. Plus, in most respects that matter to audiophiles headphones have better sound. Anyone not see the irony?

Let me explain:
- DALI recommends a "balanced" setting, i.e. not too far and not to close from boundaries but no toe-in (so keep your speakers parallel);
- Raidho recommends as much space as possible between speakers, even if those go less than one foot from the side walls and an "aggressive" toe-in, with the speakers aiming at your shoulders;
- Wilson Audio recently issued the "Duette", recommending a near-back wall placing and no toe-in;
- Audio Note speakers are designed to work in corners, with any toe-in required to achieve best bass response;
- finally, Dynaudio recommends their speakers be placed well clear of boundaries, closer than the distance to the listener and with no toe-in.
And this is just about "standard" electrodynamic designs, leaving out omnis (think MBL), planars (think Martin Logan) and horns (think Avantgarde).

"Don't follow rules, follow your ears!"

This my friends should be the rule! Listeners need to develope their own personal method of successful listening.

All:

I have found this thread very rewarding in the depth and competence of the suggestions.

In short, Thank you.

I have fallen back to my main listening room, as I really do need to do scientific research in a dedicated, quiet space. (the home office I temporarily stole to try as a dedicated listening room). My goal was never to have this room permanent ..it was just to experiment. Unfortunately, I do not have the time and budget to tune a temporary space...was hoping it was inherently "better" than my original main listening space was all.

Even though on the outside my experiment seems a failure, I instead again have gained a lot of excellent advice from a diverse group of talented people.

Thank You All,

Ron
