Owning a Trinnov Amethyst, I never really bothered engaging SO on my KDS, it just never occurred to me how SO could improve listening further....How wrong I was!

When upgrading to the Katalyst earlier this year, in a moment of madness/inspiration, I thought I would try following the basic Linn SO guide, and subsequently this thread, for additional optimisation - beyond the rabbit hole.....I could not believe the further listening improvements I was hearing.

Prior to using SO. Whenever I would switch the DSP out and bypass the Trinnov room correction, the music would sound flat, one dimensional. In fact a dealer friend who was here one occasion, couldn't believe he was still listening to the KDS - his words, "where's all the soul gone?". Now after using/tweaking SO, the difference when Trinnov is bypassed, is much less noticeable. The music retains all its soul.

SO is the basics of getting your room to play fair, the Trinnov allows me to further tweak the results based on my mood and music.....Thanks Linn and Paulssurround

Thanks Evo,

Glad it was helpful, as we all explore this journey of Space optimization.

Linn has provided us with a great tool to get the best out of our Linn systems. Big Grin

I was looking into the shoutiness and vocal depth issue (Ophelia by Natalie Merchant is a good example that I am now using). You said in the original post:

Quote:Okay, you are listening to your music and playing your favorite reference music tracks, and notice that female vocals are shouty or have sibilance. You notice that the soundstage is detailed but flat. You notice that the piano doesn’t sound quite right.
You notice that a male or female singer’s voice doesn’t have enough body and depth to the lower range of their voice.

I tried your suggestion re. the 60 and 70Hz ranges. Some improvement. But I have found the most effective is the 50Hz range. Just as an experiment, I turned mine off (at 54.86, LW- mode) and.... bam! Best ever. Deep, and what shoutiness there was is gone.

Explanation? None. Any ideas why this should be?

Just Listen Smile

Well, at a guess...

An axial 'L' mode simply means a standing wave that is set up between the front and back wall - half the wavelength being the same as the distance between the walls. So the sound is bouncing between the two walls and that frequency builds up as a result as the peaks and troughs of the waveform add together as the sound wave bounces between them.
Similarly, a 'W' mode is a sound wave that bounces between your left and right walls. 'H' between floor and ceiling.
An tangential mode, 'LW' means that the sound wave bounces off all four walls, front, left, rear, right - going right around the room. Therefore, if there's any obstruction such as a chimney breast, bay window, or if one of the walls doesn't actually exist (ie in an open-plan setup), the sound won't bounce off all four walls to complete a circuit, so the standing wave won't build up.
In the case of fireplaces or bay windows or if there are four walls but they're not parallel, that's not to say that the sound won't find a different path to bounce around - in which case, it's the length of that path that determines the frequency of the room mode - and could well be quite a bit longer or shorter than calculated by SO - and hence a different frequency - probably beyond the +-2Hz that SO allows you to adjust a calculated mode filter by. The fact that it's bouncing off at an angle also reduces the strength, which is probably one of the reasons why the SO guide says that those modes will be over-compensated.

So, if you don't have the standard four walls as described in the SO model, you can probably safely dump the LW mode. If you have a chimney breast or bay window etc, it would be worth trying different frequencies to see if you can pin it down that way.

But at the end of the day, Paul's method of 'just listening' is probably just as valid, even if it might not be dealing with room modes as such, rather just using SO as a killer graphic equaliser.

I do have an inglenook with wood mantel, and an open 'corridor' through to the kitchen, both on SO's front wall, so that could explain it.
I may try re-instating the mode and playing with it's gain and frequency as you suggest. Or it could be an invalid filter. We shall see Smile

For example, if your calculated room mode 1 is in the 32Hz to 49 Hz range, there is almost certainly a real room mode in the mid to low 20 Hz range or may even be below 20 Hz. Thank you Linnrd, for this helpful discovery.

I have learned that different speakers seem to respond to specific frequencies. For example, my Akubariks benefit greatly from a custom room mode 1 at 21.5 Hz. I usually start with a gain of -10.5 for this custom room mode and a bandwidth of 0.014427.

...

What do you do if Konfig has already calculated a room mode 1 in the 20 Hz range?

I have seen enough Linn systems now, that I can say that sometimes SPACE optimization does calculate this lower frequency room mode in the 20 Hz range. If that is the case, then I adjust the frequency of this calculated room mode 1 up or down in frequency as well, to see if you can capture the specific frequency, and zoom in on the specific frequency that is excited. Then create a narrower notch filter at that frequency.

Thank you Paulssurround for sharing your experience, knowledge and conclusions! One question with connection to what you write above: if I understand you correctly, a custom room mode 1 at approx. 21.5 Hz has worked well for all Akubariks that you have listened to and worked with, not just your own Akubariks?

I have a calculated room mode 1 at 26.98 Hz. Any thoughts on where to start tweaking this one - is the text above that I have marked in italic, applicable or do you think I should do something else to take into account the custom room mode 1 at 21.5 Hz?

Hi Linncredible,

I would certainly try a custom room mode at around 21.5 and see how it sounds.

I think my custom room mode is actually around 21.13 at the moment

Thank you Paul for your excellent suggestions concerning my system! I have now added 3 custom filters:

1: 21.2 Hz, -10.5 db, 0.014427 octaves
2: 63.5 Hz, -7.10 db, 0.014563 octaves
3: 74.30 Hz, -7.10 db, 0.021457 octaves.

There might be room for some further small improvements, tweaking the gain on custom filter 3 (maybe 2 also) some more. However, the result right now is a great improvement when compared to before. Thank you for sharing so generously Paulssurround! Smile

You are more than welcome.

That is great news. I am glad it was helpful.

The more SPACE optimizations I do on Linn DS systems, the more I am amazed at what it can do to have a profound transformation in sound quality.

I know of no other Hifi manufacturer that provides a means for it customers to get so much from their stereo systems with a bit of tweaking using SPACE.

I have now worked on everything from Tukans to Komris, and the improvement in sound quality when using SPACE optimization has been mind blowing. Big Grin

Oh snap! I disappeared! Sad

But really a lot has been going on and nothing has been going on. Basically, I've just been getting my ducks in a row. I have new speakers now, so Tekton Double Impacts, which means that my $15k AudioPhysics speakers are covered up in the garage.

I've also purchased some acoustic panels from GIK (which means I'm broke). I'm in the 13x10x8 room.

Now, here's the thing. I'm almost done with the panels, but I have no idea how to measure for SO now, since I have removed the front walls from behind the speakers.

Pay no attention to some of the scribbles there, because the windows are now replaced with acoustic treatment. The angles of the speakers are a little different in real life (the pic doesn't account for proper toe-in), but what has me flummoxed is who to I measure the front walls if the rear of the speakers has no walls?

The sonic benefits to getting rid of the front walls have been superb. Getting rid of all right angles in the room has been great! Of course there is still a wall in between the speakers, but it has freed the speakers up. So...Okay, I'm about ready to dig deep into SO. Will I still be able to do it with this configuration?

The front wall and speaker positioning is almost identical to mine with the exception that both openings are functional doorways which need to be used in my case, so the speakers are a bit nearer together and have a bit of wall behind each of them. In addition, I sit symmetrically in the room (although I must admit I find your asymmetric positioning an interesting idea!) The other end of the room, in my case, is a simple rectangle and the room is also a bit longer, however, I suspect that would probably tend make the room acoustically worse than yours.

I spent many months (on and off) with no success as far as SO is concerned, However, when Paussurround turned up, he managed to get things singing in a remarkably short time - thanks again Paul! Big Grin (Actually, I think the time was probably a bit too short, but when there's a flight to catch, you can't take any chances! Sad

As far as the measurement is concerned, my guess would be to measure from the mid-point of the front of the speaker to the front wall or the virtual extension of the line of the front wall for the other speaker. Similarly from the centre of the outside side of the speaker to the wall / virtual extension of the wall. And that is just a guess! However, if you have a microphone you could try generating sweep tones and analysing them with something like REW (Room EQ Wizard) to check that the main modes are correct

Conclusion: it will probably be possible to get really good SO results, but it will either take a lot of time and patience or the assistance of somebody like Paul, who's done SO a few times before.

Thanks Roy.

Evolvist's room setup certainly has similarities to your room setup.

Doing a bit of research on the Tekton Double Impacts, I notice they are ported in the front for the mids and ported in the rear for the bass drivers.

I would think these speakers would benefit from having a front wall behind them, as that would tend to reinforce the bass. If you are getting good results with them now, I would try to enter the room dimensions into Konfig as a rectangular room, and not include the door openings at the front of the room if there is no physical wooden door. This will simplify the calculations for the room modes.

The speaker placement in the room with regards to distance from the walls is very important, as well as accurate measurements to your seating position in relation to your front and side walls.

Having the speakers at different distances from the front and side walls will produce a set of calculated room modes that will differ significantly for gain between the left and right speakers. By having the speakers placed symmetrically the same distance from the front and side walls will simplify the calculated room modes,

However, the proof is in the final results, and what sounds good to you, so the current layout may be excellent for sound quality. It may have possible advantages of not creating standing bass waves given that the layout is not symmetrical?

Evolvist, I was thinking it would be advantageous to have some pictures of the room, showing your speakers with the listening position.

Yes, thanks, Roy! All interesting feedback. As soon as my daughter gets back from school I'll have her snap some pics of the room, since her iPhone takes great perspective photos, while my phone sucks.

In the meantime, Paul, I know you dig a challenge. You're a great guy. You're also correct, as far as standing waves in the room, from the way that I understand them, are almost nonexistent. I've taken my SPL meter, and calculated 80db in the listening position, and this is pretty uniform throughout the room, only peaking when you get to the corners where the walls meet the ceiling, but merely a +2db there. In fact, ceiling traps do not enhance the sound at reflection points. They do the opposite, buy muddying the sound and creating uncomfortable energy. I've read a lot of your writings, Paul, and understand completely when you talk about a feeling of discomfort and fatigue because of room problems.

So, in theory, I suppose I could move my speakers to be square within the the room, all at right angles. This would still mean that the left speaker would have no left wall, and the right speaker would have no front wall, since it would have to remain roughly in the doorway.

I should note that I'm getting very solid center image. Everything is set up symmetrically, it's just that I've tilted the room at an angle to avoid certain problems inherent in most rooms. I just wonder, by doing so, if I've created something that SO cannot work with, which would not be good.

I should note that I'm getting very solid center image. Everything is set up symmetrically, it's just that I've tilted the room at an angle to avoid certain problems inherent in most rooms. I just wonder, by doing so, if I've created something that SO cannot work with, which would not be good.

Hi Evolvist,

If you are getting good results as it is, then work with Space optimization using your current placement of speakers and listening position. Carefully measure the dimensions as you enter them into Konfig.

If it were my room, I would move both the speakers the same distance from the front wall on either side of the rack on the front wall, but move the speakers closer together. Then the left speaker will have a full wall and the right speaker will have a partial wall.

I would not worry about the opening to the left of the left speaker, nor the opening behind the right speaker if you move the speakers closer together.

Please let me know how the two scenarios sound with Space optimization enabled?

Thank you, Paul. The thing is, I don't know how to measure from where to where anymore, as it relates to the front walls and side walls, since they are all at angles. I did some measurements last night, turned on SO, and it sounded like crud.

So, here are the pics. First, the front wall, then the rear wall. Note, it is all under construction, since I'm taking panels on and off, doing measurements, etc., with no cable management at the moment. Those big panels on the rear wall are bass traps with scatter plates in them, dedicated to my pop idols (I mean, I could have put my classical idols on there, but my wife wouldn't have it, plus, there's just something about Bach's ugly mug that doesn't sit right). Huge panels! I custom designed these and had GIK make them to cover that awful glass back there. Note, also, that even the rear wall, if I took the room out of a cant, there are no right angles, anywhere.

I'm probably going to need some online help from the resident experts here, so that one day I can repay the favor in kind. Big Grin

Ugly speakers, great sound!
