Copie 4345

[cricri]

Hello everyone,

I'm new to the forum, and I introduced myself to yours.

Am french (nobody is perfect!) And I live in Normandy, I am passionate about food and listen to the JBL 43xx series, I have a pair of 4333A, 4315A, L300, L65 Jubal, and I make copy of a pair of 4345 with plans found on this forum
it is almost finished I lack the filters and badges.
I'm looking plan, or directly from filter 3145, you have given me advice for my project finished.

excuse me for the translation but I'm very bad in English, like many French, I think, I use google translator to write you.

3145 network.pdf (http://www.jblproservice.com/pdf/Network%20Schematics/3145%20Network.pdf)

It's kind of hard to read and I've redrawn it and posted it somewhere on this website. If you need to know any specific values just ask.

goodnight Thread

Thank you for the plan, I had already, I find the site of other plans and you gyskar but I'm a bit hidden with the translation! I do not know which one is best? people may not be exact we do tests to test the other plan with 4345, you want pictures of my body JBL 4345 (clone)



Bonjour à tous,


Je suis nouveau sur le forum, et je me suis présenté à la vôtre.

Suis français (personne n'est parfait!) Et j'habite en Normandie, je suis passionné au sujet des aliments et d'écouter la série 43xx JBL, j'ai une paire de 4333A, 4315A, L300, L65 Jubal, et je faire une copie d'une paire de 4345 avec des plans trouvés sur ce forum
il est presque fini, je manque les filtres et les badges.
Je suis à la recherche plan, ou directement auprès de filtre 3145, vous m'avez donné des conseils pour mon projet fini.

excusez-moi pour la traduction mais je suis très mauvais en anglais, comme beaucoup de Français, je crois, j'utilise le traducteur Google pour vous écrire.

amical

Yes, please post pictures. It is allways nice to see how projects take form!

[cricri]

Hello

I'll take pictures this weekend and posted for you, I also looking badge of L-CSA and grill for 4345, or you one can find it? also tissues for grids

cordially

4635046349463484634746346Hello everybody,

As promised here are photos of 4345 clone fund, it is not finished yet, I hope to have time this weekend.

the plan that I found on the forum is very well He commend?

I need your valuable advice for me not mistaken.

thank you pour votre aide.

Bonjour

Je vais prendre des photos ce week-end et affiché pour vous, je cherche aussi insigne de L-CSA et les faire griller pour 4345, vous ou on peut le trouver? également des tissus pour les grilles

cordialement

Oops!

I forget to set the terms of crossover, it is He commend the best?

[4313B]

No, I finished the final version of the equivalent network last weekend and ordered a few new parts from Parts Express this week. I'll probably start putting the networks together this weekend barring graduation parties, kids birthdays, social events and all that stuff. If I can't escape those things, then next weekend. I am extremely pleased how the final version has modelled using actual driver loads compared with the stock network.

Maybe I'll plug the network shown above into LEAP and see just how far off it is. I believe that I did it using Circuit Maker 2000 years ago.

[cricri]

I understand this plan is not better than the original plan JBL?

I is not a filter for my clone 4345, I can plan to use you one made?

GOOGLE The translator does not translate very well, it's not easy to understand.





Non, j'ai terminé la version finale du réseau équivalent week-end dernier et a ordonné un peu de pièces d'occasion à partir de pièces Express cette semaine. Je vais probablement commencer à mettre les réseaux ainsi que ce week-end de limitation des fêtes de finissants, anniversaires enfants, activités sociales et tout ça. Si je ne peux pas échapper à ces choses, alors le week-end prochain. Je suis extrêmement heureuse de voir comment la version finale a modélisés en utilisant les charges réelles par rapport aux pilotes du réseau stock.

Peut-être que je vais brancher le réseau ci-dessus dans LEAP et de voir à quel point c'est loin. Je crois que je l'ai fait à l'aide Circuit Maker il ya 2000 ans.]

Do you already have all the drivers ready?

[cricri]

yes I have all the HP, but with a small difference 2241h, K110 edit, 2405, 2420.

I have only to make the filters.

[Quote = pos ; 290231 ] Je vis à Paris , pas si loin :D
Avez-vous déjà tous les pilotes prêts ? [ / QUOTE]

[pos]

The 2241H is not appropriate. You need real 2245H's. You should also recone your K110 to 2122a. Ferrite frames would also be better.
I think member 4313b also has an equivalent network for the 2123H that is much more easy to find than 2122H.

[cricri]

I will try anyway with a membrane 2241 that less severe than the 2245, and the K110 is to change the aluminum dome was removed and replaced by a cardboard dome, I'll see how he plays the music, I have a friend who lives in Paris who owns a pair of original 4345 so I will compare the two versions:):D




Le 2241H n'est pas appropriée. Vous avez besoin de Real 2245H . Vous devriez également remembranage votre K110 à 2122a . cadres de ferrite vaudrait mieux aussi .
Je pense 4313b membre dispose d'un réseau équivalent pour le 2123H qui est beaucoup plus facile à trouver que 2122H .

Bonjour à tous,

J'ai presque fini, je n'attend que le condensateur du filtre et il est parti, je suis impatient d' écouter les orateurs , puis comparer à mes 4333 et 4315.

46778Hey everyone,

I received the capacitor and set up the filter, I am surprised at the values of middle outlet that is not related to acute and acute super!:blink: middle = 19,848 ohms, hf=4,487, uhf=3,818.

I installed the filters in the box and away it works, but it works badly, I think a break is normal at first. After four hours of functioning that begins to feel better I am reassured. :D

I will keep you from further development, and I think it will be hard, having regard to the sound of my bass I think hemp wool is too thick (1.5 inch) 40 milimetres must I replace it with something less dense.

- The 9 volt battery feeds its' positive voltage ( + ) to the junction ( of the twinned ) capacitors through 3 mega ohm resistors ( 3M ohm ) . Your pictures don't seem to show these ( tiny ) feed resistors .
- Hopefully, 3 Mega Ohm is the value that you used in your network ( and not 3 ohm resistors ) .
- If you used a value substantially less ( than any value in the Mega Ohm range ) / then you are shunting audio frequencies of those twinned capacitors to ground through the 9V battery ( that'll surely give you audibly bad results ) .


<> cheers

[yggdrasil]

Your inductors will interact when placed like that.

They interact less when placed in different directions, i.e. put a standing inductor next to an inductor lying down.

[cricri]

[QUOTE = Earl K ; 291881 ] - La pile de 9 volts alimente sa « tension positive (+) à la jonction ( de l' jumelées) condensateurs à 3 méga résistances ohms (ohm 3M ) . Vos photos ne semblent pas montrer à ces résistances aliments pour animaux ( minuscules ) .
- Espérons , 3 Mega Ohm est la valeur que vous avez utilisé dans votre réseau ( et non pas les résistances 3 ohm ) .
- Si vous avez utilisé une valeur nettement inférieure ( de n'importe quelle valeur dans la gamme Mega Ohm ) / vous êtes de manœuvre des fréquences sonores de ces condensateurs jumelés à la terre par la pile 9V ( qui va sûrement vous donner des résultats audible mauvais) .

Hello

the resistance are doing the 3.3 mega homs 1/4 watt, I had it available, I do not think this is a great influence on the sound quality:( by cons that I had also resistance as 22 ohms 10 watts instead of 20 ohms He commend my problem can come from here? I myself perceived also that my diaphragms of 2420 was 8 ohms (5.3 ohms actual)
:banghead:can I have a shame I did not strictly following the 4313B, I hope that it will be able to help me.;)

Thank you for this information, I do not know!:)

I corrected this,;) after many hours honing the sound gets better:D

[pos]

here are some guidelines

[pos]

4313B, what would be the best bet for a 2123H / 2425H / 2405 network?
I was thinking about the 4344mk2 network, the only real difference being the aquaplassed 1.75" diaphragm vs bare 1.75" titane diaphgrame of the 2425H
Do you think it will make a big difference?

Do you think it will make a big difference?Yes, the 4344 Mk II network is a turn-key solution.

There is roughly a 1 dB difference between the non-aquaplased and aquaplased diaphragms. The L-Pad will handle that.

[pos]

thank you :)

[4313B]

here are some guidelinesJust for fun, notice the inductor orientation on the K2-S9900.

[cricri]

[QUOTE = 4313B ; 292459 ] Oui , la 4344 Mk II réseau est une solution clé en main.

Il est à peu près une différence de 1 dB entre les diaphragmes sans aquaplased et aquaplased . La L -Pad se chargera de cela. [ / QUOTE]



Thomas Goodnight, goodnight Gyskard



Thank you enormously for the helping hand that really make fun of people found on the Forum to help others without the fun of them about things off topic, is really pleased that I advance on this project haunted me for several years, I am on vacation for less than one week and I miss it already! it is amazing what speakers are really what I have heard better, I'll run the filters for some time, about the break-in filters it is time how long?



in all cases I made the filters with identical 4344mk2 and forth those authorities in order to make tests more easily.



still a very big thank you to POS are helpful and are working to gyscard helped No Information produced around the world and up-graded these grandmothers JBL :applaud:


I will inform you of my endurance tests of filters on my 4345 clones :D

[pos]

Would these Lpads work for the 4344mk2 network?
http://www.parts-express.com/pe/showdetl.cfm?Partnumber=260-252
http://www.audiophonics.fr/attenuateur-pour-enceinte-impedance-constante-at52h-p-5299.html

Also, would somebody have a close picture of the 4344mk2 foilcal, to see how much attenutation is needed for the "0dB" position, and also check if 300° is the proper adjustment range?

[4313B]

I use the 1" shaft version.

If I remember correctly, the 0 dB position on the Mk II foilcal is at 3 o'clock instead of the usual 12 o'clock that we are used to, so there isn't much play left if you are going to use it full passive with a 2245H instead of a ME150H. I think it will just work. Of course bi-amping makes that a moot point. Triumph Don has a pair of 4344 Mk II's and maybe he can post a photo?

[cricri]

He commend someone already used this model it: http://www.public-adress.fr/pr-car-562/DIY/Attenuateurs/Attenuateur-a-impedance-constante-Monacor-AT-62H.html #

would he not best suited for medium and medium high.

Hey everyone,

I found it on ebay germany: http://cgi.ebay.de/1-m-Akustikschaum-Pyramiden-Dammstoff-PYRA-3000-HL-/140426253120?cmd=ViewItem&pt=Lautsprecher_Selbstbau&hash=item20b20e9340

is that it would be better equipped for my 4345 clones as wool hemp 40 millimeters that I've been inside the boxes?

[pos]

Hi Christian,

Why don't you use normal fiberglass insulation?

The foam in your link is not thick enough to be efficient in the frequency range of the woofer, as can be seen in their absorption graph:
http://www.dinaflex.de/images/pyramiden/Mittel_und_Hochtonabsorber.jpg


Pourquoi n'utilise tu pas de la laine de verre?

La mousse de ton lien n'est pas assez épaisse pour être efficace sur les fréquences basses du woofer, comme on peut le voir sur leur graph d'absorption

[jerry_rig]

The foam in your link is not thick enough to be efficient in the frequency range of the woofer, as can be seen in their absorption graph:
http://www.dinaflex.de/images/pyramiden/Mittel_und_Hochtonabsorber.jpg

It isn't clear to me that the point of cabinet insulation is to absorb all frequencies. As most here would agree, too much insulation yields a lifeless sound. What you don't want is sound waves reflecting back out through the woofer cone. Only medium to higher frequencies are the problem here. So, I think he's probably fine with this material.

[pos]

The 2245H plays in the 20Hz-300Hz range, so if there is no significant absorption in this range why stuff anything in that box in the first place?
This material is very expensive and those little pyramids are of no use at the frequencies he is interested in, so why pay premium when he could just get away with the original fiberglass stuffing material, and get a better result?

[cricri]

[Quote = pos ; 293012 ] Le 2245H joue dans la gamme de 20Hz - 300Hz , donc si il n'y a pas d'absorption significative dans cette gamme de quoi que ce soit des slideshows pourquoi, dans cette boîte en premier lieu ?
Ce matériel est très coûteux et les petites pyramides sont d'aucune utilité aux fréquences , il s'intéresse, de salaire majoré , alors pourquoi quand il ne pouvait s'en tirer avec seulement la fibre de verre originale de matériau de rembourrage , et obtenir un meilleur résultat ? [ / QUOTE]



Thomas Salut,

Je pense que le chanvre laine 1 3 / 4 pouces d'épaisseur que j'ai utilisé pour mon 4345 clones altère le son de la fréquence trop faible . Je n'ai pas réussi à Touva de laine de verre de 1 cm ou moins:dont-know: , que ce soit dans mon 4333 ou mon 4315 est juste l'épaisseur d'un pouce, c'est pourquoi je pense que l'utilisation de ce produit n'est pas si cher que, compte tenu de l'annonce sur eBay Allemagne .
Je suis sûr que le forum , il ya certainement des gens qui sont déjà confrontés au problème .

[4313B]

The fiberglass insulation adds virtual volume. Basically it negates the volume displaced by bracing, subenclosures (within reason), drivers, ports, etc. You can use other materials but then you will need to plan for their volume displacement or lack thereof.

[cricri]

[QUOTE = 4313B ; 293029 ] La fibre de verre isolant ajoute un volume virtuel . Fondamentalement, il nie le volume déplacé par contreventement , subenclosures ( dans des limites raisonnables ) , les conducteurs , les ports, etc Vous pouvez utiliser d'autres matériaux , mais il vous sera nécessaire pour préparer leur déplacement de volume ou de l'absence de celle-ci . [ / QUOTE]


So if I understand correctly, the original fiberglass JBL is not very dense, the volume taken by it is nonexistent, by cons if I replace it with another material denser I must take this into account and recalculating the volumes?

Giscard forgiven me if I misunderstood:confused:

[cricri]

Bonjour à tous,


environ 30 heures après avoir consulté les filtres sont de mieux en mieux , alors j'ai enlevé la laine de chanvre et le son est beaucoup mieux je l'ai commandé sur eBay Allemagne : http://cgi.ebay.de/5-m-Pyramidenschaumstoff-Dammung-PYRA3000-/130415343435?pt=Allgemeines_Musikinstrumente_Zubeh % C3% B6r (http://cgi.ebay.de/5-m-Pyramidenschaumstoff-Dammung-PYRA3000-/130415343435?pt=Allgemeines_Musikinstrumente_Zubeh %C3%B6r) :bouncy:
Je paie 40 dollars à 20 plaques de 0,5 x 0,5 mètres , je décorer l'intérieur du boîtier .

J'ai fait une 4344MK2 filtre à comparer avec celle de Giscard que je réalise déjà mon équipe et clones 4345 .

Je suis passionné par ce projet, mais il me prend beaucoup de temps

J'ai joint une photo de mon système
