Romy, after reading my previous post I realize I would have to express myself more clearly, sorry for the misunderstanding! This hobby is an important part of my life, I have specific opinions and am probably not less serious about them than you are....

[quote user="cv"]Romy, Can you expand a little more on what the issue with dipole bass is and what it does incorrectly? I'm still not sure I know exactly what you mean (and I've had a look at some of your other comments on the site).[/quote]Chris,

Hard to comment on this one... Seems like most everyone I talked to there hears with their eyes, and thought they were beautiful sculpture, therefore sounded wonderful... Maybe I should just be honest and say I flat didn't like the s...

[quote user="el`Ol"]IMO you can never get realistic imaging from dipole.[/quote]
this is almost certainly true.
[quote user="el`Ol"]Here is a very detailed description of a dipole horn for the BG Neo 3.

With stereo you hear sound from more than one source (speaker) and the sound from each source is very nearly the same except for some variations in amplitude of certain frequencies and some phase differences which occur because the microphones us...

The ideal horn system would have to be well integrated into the room, acoustically as well as optically/cosmetically. As far as a commercial venture goes, I believe that Marc Henrys "La Grand Castine" was already (except for the ULF dipole panel) ver...

Allo
Well, my baffles are for a vertical array. A friend of mine built a "clone" of the Nola Grand reference and got a very good deal on the G1 ribbons... will send you a PM.Don't be pissed about me keeping you in the dark regarding the ribbons; you...

[quote user="el`Ol"]Weren't these speakers (at least in Germany) normally used built-in (infinite baffle situation)? And I don't like the word "open baffle" because it can mean anything. It reaches from quasi-IB like proposed by PHY-HP up to that mor...

Macman, the “annoying peaks above the usable frequency range” is something that your specific installation might have in context of your room and your acoustic system location but it might not be a characteristic of tapped horns. I do feel ...

Another few months and the guy from Moscow have another change: http://www.soundup.ru/index.php?option=com_content&view=article&id=4296:2014-01-09-11-48-09&catid=91:2013-&Itemid=111 The text shall be translatable, even though I was no...

[quote user="Markus"]Interesting take on the Altec 820. No way can this be done for 20k. Looks like dipole bass with some attenuation for mid frequencies.[/quote] Markus, the price of this thing might be anything they want. They can set if $100K and ...

This is what I try to stick to: Try to create closed magnetic (steel) loops around magnetics. Ideally acompany itwith closed electric (copper) loops. This I think Pieter has done that already for you, but,as Romy impicite suggests, double boxing will...

Hi all,In my experience it is VERY hard to get anything resembling realistic bass from a vented box, particularly with a Q of around 0.9 or 1. There is too much stored energy in the system and too much overhang. The best bass I have heard...
|
|
[quote user="Romy the Cat"]our logic is correct but you refuse to see the whole picture - this is the biggest mistake the admirers of the open baffles do. Let trace the entire process. You grow the size of the baffle in order to keep the speakers to ...
|
|
I see, this tri-way Quad system for sure shall be much different from regular Quas. I kind of even understand why you stay with open baffle bas to support the system’s bass. For sure it will not Bruckner-style pressurize a room as non-dipole bass wou...

A “casual” look at full range usually results in 3 or 4 way playback for standard dynamic drivers or horns. There are a handful of “full range” commercial efforts from Edgar, Wilson, JBL, etc that are doing similar things with the range of each chann...

This weekend I decide to take my FM where it should be. I ran ~125” and installed a dipole on the roof of my building and serviced my tuner. The result was as expected but there was something unexpected. Along with all normal benefits of better anten...

Well. That dude down my street in the esoteric shop would say "i feel negative vibration is in the air here"...Though "only positive counts" may sound very positive in the first place, it rather seems to be used for discrediting majority of opinions....

|
moreart,It is the theory that you feel comfortable with but I am not. If you compare a radiation from a single 40Hz transducer and a dipole 40Hz transducer then you will recognize the differences. Also, you look at the 40Hz but I ma talking about a ...

Quickly again, for the record, and The Google:The back wave of the Manger has a much less flat response than the front wave. There are peaks out the back. It is not a symmetrical dipole. This issue is only of interest if you are using the back ...
|

Thanks for the detailed answers. I will explain my setup.You are right about the dipole bass correction instead of the injection channel. Since I am waiting for both a subwoofer and the Fane Studio 8M and their horn, I am using the 12" as a b...
|
|
Well, it unquestionably much better, still I am afraid that they are trying to spread one ass across two chairs; I will talk about it in the end. The change from what was before was around the frame and upperbass horn. It looks like the guys are tryi...

[quote user="cv"] Don't be pissed about me keeping you in the dark regarding the ribbons; your comments elsewhere on the Nolas and ribbons in general had me loathe to make any recommendations. I think we may have very different tastes in terms of tre...

Richard, I think we should differentiate (and this should be applicable no only to this thread/post but to whatever you might read on this site) two very distinctive things: a seriousness on the subject and a seriousness of “perceive ourselves” on th...

I have 2nd order crossover both on the upper knee of the ob bass section and on the lower knee of the midbass section. My measurements show phase response and the summed spl is as good as it can get. Have you tried the direct servo technology or do y...

[quote user="guy sergeant"]Hi Romy,My experiences with the SL6 and SL600 date back 15-20 years. My problems with the sound I could get from them related to their inability to recreate music with scale or drama. I found the subjective lack of high fre...

[quote user="guy sergeant"] I don't think I'd be tempted to make a back loaded horn to begin with. [/quote]
Yep, it is what it is. The back-loaded horns might have as convoluted back path as Scriabin music is but the sad truth about them is th...
