I.S.C.T. - 'Hearing Music The Way The Artist(s) Intended It To Be Heard'

[UpperCut]

Next up no. 2: I assume best suited for ... well, very wrong! as I have used these now in a Hi-Fi & automotive set up, and I'm smitten with its performance! yet of course need some more measurements for really judging, but they sound graet if not better then the system I sample with. Usefull for 6x9, 6.5" & 8" with PR(s) - (presently AS IS shown in my Images they are running around 40 Hz). I always claimed myself that 6x9 speaker chassis were underestimated and are I mean if you find a good one can be used in many different settings!





Next up no. 3: Great performing set up especially with these Ifinity which are very good speaker chassis (factory specs 46 Hz).

The next Image shows outer and inner decoupling rings A) left side white outer speaker decoupling ring & an inner ring both for the 8". Middle one is a 10" outer ring again & an inner one this time with threaded rubber nuts. The third set are both inner decoupling mounting rings for two 12" PR's.


This Image now is showing the two drivers I will use, and as well as two more options of using the exect same enclosure as above in a different way!


Well, that is it for today but more will come ASAP - some of the main items are getting covered at the moment!

Do you do box modelling?

Hi there, thanks for your reply! Please could you explain a little more in detail what you are looking for, but in general YES if you mean enclosure modelling. rgs UpperCut

Your info would be more interesting if you gave box volumes, tunings, and provided Qts, Fs, and Vas for your drivers (or your own sim graphs). Do any of your projects use passive XOs?

Hi there,
It is of course questionable what anybody is looking for by preference !) it could be the graphs or another maybe not 2) the second likes something else and the third something different again!
As in my case I have such all behind me because in the end it was mostly all questianable as this was not right or missing or something else to get some results pleasing enough!!! But as you mite have noticed the no.2 & 3 using 6 x 9 which is mostly Impossible to get a full set of data anywere they are just not suppliyng all of that freely as it is automotive??? So no.1 is in construction and as that is a Hi-Fi item that will have in time the right data provided.
This particular design build up has a lot of data enough to judge what was needed, but in general this design was outlaying & trying to prove the missnoma / disbelieve that of angles .....
I'm personally have given up in the search for clinical sounds rather addressing issues which really matter in audio & with that in the sound reproduction - developing enclosures towards the chassis specifications not the other way around and in that I find my answeres including placement and angles. The final outcome is determent by proper audio physic & real experience not just by a set of graph which by the way once you do your homework properly come out just like intended so that you are at an stage of finetuning not guesswork!!!

Sorry, forgot YES passive crossover some times as needed or tested I have a few so I swap alot to find different answeres to different items yet always on a quest to improve or to find limits in what I build.

Well, that is one classic answer. You might think of running for our new President. We vote this fall. It's a 4-year term. Anyone can do it. (You might have to be U.S. citizen. Maybe not.)
I offer this for your reading enjoyment.

I have also built maybe 30 projects over the last 15 years. Maybe more. Maybe less. I have built boxes from 5cf down to as small as 0.05cf. Mostly in-between. I like to use drivers almost always no larger than 15" but no smaller than 2-1/2", unless they are tweeters we are talking about. If tweeters, I THINK they've almost all been about 1" dia. Some might be a little bit bigger, but I think at least once I used one a little bit smaller. Maybe not. I also plan on using a VERY expensive ribbon some day. I hope.

I've never used an "off the shelf" XO. I can design pretty good ones today, but not so good when I first started. Some 2-ways. Some 3-ways. You pick. I've also built subs from 6" to 15". Built an 8" once. Also built a 10" once. Also designed 1 or 2 12" subs, maybe 3, maybe 4, maybe more. Maybe not. Various brands. I like to paint my speakers white. I have pictures too. You can build one if you want. They all sound good. You can't please all the people all the time.

Re: I.S.C.T. - 'Hearing Music The Way The Artist(s) Intended It To Be Heard'

Hi again,

Not quiet sure were the agro comes in at this my comments were not mend offensive at all it rather mite be my way of writing in English!
Anyway, now as I read your reply I’m honestly not sure if I understand it??? I’m sure that you have had your own build and I never ever would be judgmental about it why should I – I have given up on that any moons ago, but I know that it is not easy to comprehend at first what it is all about what I’m doing.

It is a great problem not only for me, but in general to convey something of such magnitude such difference of sound reproduction in writing what it is and what makes these units so very different, and believe me different they are!!! I simple put it down to the shape and angles just as I believed it would for years now!!!

Over the years now I have preferred to use in my developments Morel chassis and throughout these were an extreme suitable item yet need up to 1.5 years to really break in (Tweeter only) but at the moment I’m not so well equipped as they are quiet pricy, but I’m working on it to be able to work with them again in time to come.

Presently it is priority for me to build and with that use the knowledge I accumulated trying to proof things out of the norm of the ordinary audio scope I think, and until now that was 110% on the dot!!! And so much more of what I have or could have been expecting.


Anyway, I would like to ask you a question about audio which you are maybe able to answer for me? I have 5 projects I’m working on 1 which is the one above, and four more were is the no.4 the very-very big one which should incorporate all my knowledge, and this one I have just worked on the last few days and with that here the question!

*******
Do you know, heard or have knowledge of the following???
Semi - Closed / Vented Enclosure Arrangements like for example in a MTM configuration???

*******

This is not a catch 21 question it is something I want to build after my next one coming up!!!

A good book to read is "Speakerbuilding 201".

There is a certain collection of principles, terms, data and methods that every speaker designer knows of and practices when designing speakers. These things form the basic language all builders use to effectively communicate with each other. Terms such as Qts, Fs, and Vas are examples of the kinds of data builders look to in understanding how a speaker design functions. FRD data is another important factor as is understanding concepts in cross over network designs. Many will agree that methods such as box cross over modeling are important in producing a good sounding design.

Chris asked you about these things because he was interested in your design from a designer's perspective. Being able to understand and provide such information is important if you want feedback on your design.

I will also be brutally honest with you: The way you have documented your work--photos included--reminds me of an advertisement. You provided no substantial data about them or the way you went about designing other than "I listened to it and tweaked it until I liked it." That might certainly work for you of course, but I think you will find many here to be quite skeptical.

Plus, those photos.... are you trying to sell these? I do not believe selling is allowed here.

Exactly this. And the slogan.... gawd.

Hi there,
Thanks for your reply!

As you look at the Images presented you see the no.1 unit as raw as, and all other Images are no.2 and no.3 so I was intending to explain everything on this no.1 unit once I have more of that completed & available as the design is perfectly the same and elaborate on that no.1 unit yet also include different things for the others as well!
Only because I’m myself Artistically inclined does not mean I want to sell these yet I like to present my items a little bit more presentable, and as I’m a web & desktop developer among other things means that I look in what ever way I create my work very much more creatively and from a creative standpoint.

Whatever way you are or were used to have your info presented is fine with me yet I’m not doing it this way as it appeals to as medieval & over & over again the same, and I with any of my designs or whatever there is likes to create in this thread questions about yet as I can see you do seem not to have any which indicates to me why would I wanted seriously to share my knowledge with people totally set in there way and not at open to different things & advancement.

BUT, no surprise there as it has been this way 5, 10 or 12 years ago all the same, but I’m truly sorry to say old knowledge is not my cup of tea so I do not present it that way either!!!

A good book to read is "Speakerbuilding 201".

Is this that one from 2001 or the one 1978??? I would be happy if I could not that there would be anything else of value in it from any of which are in my Libary, but this one I do not have sorry!
All in all I think and sorry to say you are missing the point I'm trying to make here, and WHY these enclosures are so different in its reproduction of any music material gone through them. This all has nothing to do with the average set up any longer the whole way of approach is different, but therefor to find out you need to be much more open minded, and you are not oviousely.

I personally like to see & evalue my fellow audio entusiates by the questions they ask - but not by the info I present so that in any case pick holes in it without understandind. I ask you a question before yet you never answered and so it would be the same if I would mention why one of the enclosures has stainless stell cross bracong or why they are covered insted of .... and most of all why these enclosures use types of newly developed damping arrangments called ‘Air Cushioning - Area Trapped Air Arresting Motion Suspension’ and I could go on about it all day.

By the way did you maybe by chance ever heard of the following ‘Single, Double - Resonance Dispersion Panels’ as yet? All items which would be in your 'Speakerbuilding book 201 or elswere for that matter simple because that is midevil knowledge which has to let go of OR maybe not I mean if you feel happy with it stay with it at least I would - yet I was not happy with it so I spepped away from it into a new audio world full of excitment and fresh ideas.

Are you using a program to convert german to englush ? At any rate this is very hard to understand and follow what you are trying to say.

Yeah, it's really tough to get through the noise, particularly when the content seems to be such fluff- no technical anything just self-congratulation.
