It's not a well known problem and it isn't a huge problem either.
I also know that you disagree with Oehman about many things.
But I think its interesting point and not so hard to understand but a little difficult to find out how much and where this adjustnent is done.
I'm using a more a traditional BBC-dip in my own diy speakers.
So sorry I cant answer your questions about others research.

Just noticed that in my previous post I wrote "overseen" but ment "not overseen".

That Guru measurement wasn't transient perfect at all, the 3.5 way measurement of my own speakers was however. Chock one up for the DIY crowd 😀

Sorry if I used the wrong word, nearly phase linear is a better description. Silly of me to bring this up 🙂

BTW thanks for you own insights into what a "non-textbook" function means in this case.
Ok, if it´s only known as a problem in advertising of a certain brand, then it might be a imaginary problem?Gunnar said:
No marketing would work if it didn´t seem potentially true.
Wow, you really go to lengths trying to misunderstand things!patrikf said:
Is there something you need to compensate for 😉
I have had a problem with what I think you would call ambience
The imaginary "room and soundstage" was dragging to one side, but only on certain parts of an instrument and voices...at some point I thought my amps were to blame
I have cured it completely with very careful adjustments on midrange series inductor, RC and notch 🙂
Might this be the mentioned phantom effect ?

so, is there an adjustment available for ceiling height ??
what if you have a vaulted ceiling.. ???
what if you have sound deading on your ceiling??
Andy Graddon said:
Hey, this is a Swedish speaker. The Swedish standard states(?) a ceiling height of 2.2m (7.218 feet). Just order the Australian version adjusted to the Australian standard!! 😉
If you have a vailted ceiling...don´t buy it!!!!
If you have sound deading...you´r a NERD!😀
😀😉
😎About the ceiling height, if you fail bouncing that reflection into your sweetspot this doesn't make it a bad speaker. Using this technique into a 2-way MT diy project makes however good sense 😉
Dag said:
I guess you could say the standard for cheap homes is 8ft (2.4m)
because that is the minimum allowed.
Older homes often have 9ft or 10ft ceilings (this is a warm country) I much prefer this type of house !!
Newer non cheap homes don't really have a standard, certainly there is nothing in the buildiung codes except the minimum 2.4m.
Sorry, but a commercial speaker with such limitations doesn't seem like a good idea, I wonder if the salespeople would check where its being used first.. yeah.. right !!!

I don't understand your conclusion. Its not a limitation, why shold it? As long as you really dont know how the dispersion looks, you can't tell us somthing about it and how it works.
I can see that you dont like the speaker 😉 but I got no hard feelings.
Not saying I don't like it, I just can't see why all the fuss over something that is looking like just an ordinary decent 8"+ tweeter with a couple of issues.
If someone brings something with the claims that are made, please don't expect us not to try to get to the bottom of things.
In this case, any real information is still lacking, what more can I say ??

Did you do an acoustic analysis of the room to exclude the possibility that the room had severe standing waves in the problematic low frequency region?

As far as I know the Guru's that are on the market does not have adjustment. The 10-20 speakers (with many more variations) from the Ino line (that are the "ancestors" of the Guru line) are made for different rooms, listenig distances and preferences/listening habits. Some of these do have adjustment possibility in the crossover for the vertical dispersion.
Limitation? Most speakers are made without attention to polar response and dispersion..
And yes, these speakers are more or less only sold if they will be used in a set up where they will perform as intended. The designers wish is to deliver performance to musiclovers.. not to sell high volume.
So you say that your knowledge of physics and high level of expertise in the field of loudspeaker design allows you to look at a speaker on a photo and judge it's performance from that?
You talk about looks.. these speakers are not meant to be looked at, they are intended to be listened to.
There are Ino speakers in Australia, why don't you try to get in contact with those who own them and try to arrange with a listening session.. and then get back to the discussion?

Looking like, ahh fun with language differences..
I was not talking about the looks,, but the what can be taken from the information provided.
Perhaps with more information rather than rhetoric I might be inclined to search some out.
If you are seriously interested in listening to these speakers I guess you should ask Ingvar if he can get you in contact with someone downunder. Of course, I have no idea if there is someone that are willing to open the doors for a guest and a listening session.. but asking a question doesn't cost anything.

People responding with rhetorical comments, unfriendly
speculations and no appreciation what so ever for the attempts
to explain - kind of proves that informing of anything, is a bad
idea.
So, I accept that.
When what I'm writing results in angry kick backs, it rather makes
me less interested in continuing writing.
I would really have liked to clear up some things said by nice
people trying to explain, who however have misunderstood some
details a bit, but I'll pass. It's not that important.
Best regards, Ingvar

PS. People like Patrik Finn are the reason for my restrictive
attitude. I'm sorry for that, and I wish the situation were
different. But as it is today - I'd rather say nothing. No matter
what I say, there seems to be someone there willing to turn
himself inside out to misunderstand in a negative way.
The info Patrik Finn is pretending to be asking for is info that he
was offered a long, long time ago, and his response at that time
was that he was not interested - because he knew that there
were no such research done!
Shortly thereafter, I held a lecture at the royal institute of
technology regarding all these matters, for anyone interested.
People came from all over Sweden. Patrik did not.
When I earlyer invited him to my facilities, he was not showing
any interest listening to music (he started talking loudly thru the
music the few times I tried to play some tracks) nor did he show
any interest in discussing technical matters, only talking about his
viewpoint that any discussion is a fight and the goal is to win and
make the opponent look bad.
Well, I believe you Patrik Finn.
But please select someone else to stalk and torment. This has
been going on for far too many years. Or rather... select no one.
No one deserves it.

That's OK Ingvar you have nothing to prove on here, some questions weren't asked in the best manner(including my early ones) but its obvious that the design stands well in the eye's of people who have listened to it. In fact I don't really remember any negative listening impression being posted and that's pretty good for something as personal as a loudspeaker. Although having said that, there's still plenty of sceptics of course.
Good luck in your future endeavours.
