Well a scepter or a baton... Last night before setting up the RTA, I listened to a recording of orchestral works from Strauss (Kempe conducting)... It was early enough that I could "air out the system" a bit. And Ok, maybe I don't have all ...

Dear Romy,
well the horns are actually not designed for HF. The intended working range is up to 5-700. But since we use low Q, only second order filters we want to have a rather large overlap in the crossover region and a fairly even pattern over ...

time alignment?
why on earth have you got those horns aligned like that?
I have a pair of the same marinelli horns.. 15" wide. stunningly pretty, solid birdseye with tad-2001's.. i'm not impressed at all.
can't wait to put a tractrix or lecl...

Jessie,
When I spoke that I would go most likely for exponential I did not mean the Exponential vs. Hyperbolic but rather that it would not be a Tractrix. I have no specific preferences for Exponential, Hyperbolic or any other long profiles. A commo...

Robert, what I meant is following: when you will be collecting requirements for you own drivers specification and will evaluate the implementation methods then you need to have you own identity what you are trying to do. I might post a lot of differe...

[quote user="Romy the Cat"]I am not sure what you are asking. If you willing to get 400Hz horn into 1” tractrix then it might not be any controversy about the horn’s length, it is already given and the folks from lab.de will know it and will do the r...

My idea is a upright horn like your "midbass hanging thing", at 200 hz for the smaller size of it, and this will be my work for 2009/10. What I would like is exponential curve, not tractrix horn, something like this one perhaps?
this is...

I set two multicells with LF-enabled S3 drivers. I set them on the outer side of Macondo MF. Playing with crossover, volume and towing of the multicells I was able to a degree to get the effect that would like to get. The pointing the multicell...

Actually it is not exactly accurate. In the way my Macondo is a magic bullet. If you read carefully old article about Macondo axioms then you will see that one of the major underlying principle...

There is a guy named Ad in Netherland who makes looks like aluminums (but I am not sure) horns for 1.5 inch compression drivers. The first picture it looks like an exponential: W=39cm/15.4Inch. L=45cm/17.7Inch.
I do not know if Tractrix and the Fren...

[quote user="serenechaos"] If I were in your shoe I would take make as you wish but wish a slight correction:

Romy,
Just to be sure, I ran all the tests again today, but this time at various volume levels.
I got exactly the same results as yesterday.
To answer your question (sorry it took me this long) : Yes I do use metal suspension on all 4 S2s....

Ok, I have been experimenting with placement : Long wall versus short wall. Though the frames have wheels and roll very easily, my room is cursed with an elevated platform smack in the middle of everything (about 14 inches higher than the main floor)...

Hi Romy and thanks a lot for the always interesting topics and discussions going on... I'm quite new to DPoLS and consider the approach of "obtaining sound in a room" more than "speakers positioning" - too often to WAF fullfillment and aesthetics, th...

Interesting, thanks Guy for posting.
Let analyze what was done in there. It looks like well-thought, time-aligned, looks like multi-amped configuration. BTW, how the filters were implemented and what (slope/order) filters were?
To my knowle...

Jorge, that is good but a few thighs I would like to mention in this approach:
1) What you depict will work with tractrix or conical horn but not hyperbolic curve. The hyperbolic has own “swell” into exponential curve that would make it to...

I'm also of the opinion that the bass is one of the most critical and most challenging parts of playback. Not talking about quantity, but rather the quality of bass reproduction. My approach has been to split the bass in two parts - Low and...

[quote user="Romy the Cat"]I wonder: does it mean that you will take the rest 28 drivers? Hm, are you trying to research the subject of the drivers’ critical mass or become a speaker maker? Be careful with their claims that they will be “manufactured...

The system is still very much a work in progress, but I have come to the conclusion that the concept as such is very, very good. It's only up to me to make it sound as well as I know it is capable of. Making and fine-tuning the crossover might take m...

[quote user="jessie.dazzle"] Once I am done with more of this project, I will make a 330Hz Tractrix to try in place of the upper mid 400Hz. [/quote]
Hm, I wonder what would be the purpose to make 330Hz horn for you if you have 400Hz and a dedicated ...

I except suggestions and critique. I live in Turkey and I am not living in a city, I live at the coast. It is not possible for me to go and experience most of the stuff first hand. There is no one really interested in horns or have multi-way horn sys...

[quote user="Jorge"]I guess it would be simple enough to add a couple of inches in order to bring the throat down to 4" in order to try the Studio 8M. I have already reduced it temporarily to 3" in order to try the JBL 2490h compression driver. ...
