I too have his 399 drivers. I use them on 500hz round wooden tractix Edgarhorns.

I prefer JBL 15" drivers for the bottom though as they take up less real estate.

NIce looking system!:applaud:

I crossover at 2nd order lo-pass/3rd order hi-pass @ 800hz.

What efficiency do you end up with your system???

I am guessing around 100db/watt???

Good for tube amps I'm sure!

Thanks for sharing your system with us.

Nice job on your speakers.
I wonder if adding some fiberglass batting to the inside of the cabinet might be good idea?

[stephane RAME]

the store which the my sold high speaker and to give the plan, my adviser not to put a glass fibre.

[Chas]

Nice. I like the idea of using machine screws to retain the cabinet back. Allows for changes without worrying about the woodscrew hole becoming enlarged.

[BMWCCA]

Insulation wouldn't really effect the high-frequency, though maybe they were just offering an opinion in general. Back when I was a kid, and had ordered a set of components to make a mono 030 into a stereo pair, while waiting for them to arrive I built an MDF copy of a 433X cabinet. I tried it without interior insulation first and it sounded kind of hollow. Much improvement with fiberglas batting added. The benefit of interior insulation or padding is best described here (http://www.lansingheritage.org/images/jbl/plans/1979-manual/page21.jpg): (monitors, delete the image if the size becomes a bother, I coudn't resize it and the link should work fine.)

Stephane, you did a fine job on your speakers. I admire the simple yet solid construction and good materials and fasteners. It also does my heart good to see the drivers that Bill is making. I'll bet your systems sound great.

It is funny that the booklet states that JBL does not recommend rock wool for cabinet lining; that is exactly what Jim Lansing used in all his bass reflex cabinets. He surrounded the rock wool with cheese cloth and stapled it in place on the cabinet walls. Here is a picture of a circa 1940 Lansing Iconic cabinet:

Hi Stephane,congratulations you really have a nice project,i'm curious and i'll be delighted to hear your listenings impresssions concerning theese,i don't know that much about GPA but i guess it's one step further in the audioworld,i'll make a search through google in order to get myself documented,by the way,no regrets for your 4430?they were pretty nice too,regards MEvin;)

[stephane RAME]

Hello, according to what I included/understood, company GPA, are the old ones from ALTEC, which took again all the service part after sale and continues has to manufacture best the references of this manufacturing.

For GPA, to see the bonds according to: http://www.greatplainsaudio.com/

Not,je regret not my JBL 4430, it adapts better has my part , owing to the fact that they less low descent in frequencies, if not they are more dynamic, request much less power and I find low medium clearer and detailer.
Stephane.

Thanks Stephane for the link,it would be of great help for Altec owners,that's awesome,anyone can go for old Altec speakers in need of restoration,almost any replacements can be found,even for Gauss or EV.

[spkrman57]

Bill Hanuschak is a great guy and answers technical questions to help out.

Great Plains audio is a company of one, Bill that is and he was one of the last standing engineers of Altec before Extra Viscious(EV) took them over. He also bought a lot of the tool and die equipment so that the same equipment that was used for making Altec drivers is the same used today.

His drivers are good enough quality for me to buy, if that means anything to anybody.

[stephane RAME]

Hello, I ended up finding the formula for the calculation theoric of the frequency of resonnance of this enclosure.
this frequency is thus +/- 40 Hz.

WOW SPKRMAN, now that is interesting! I guess I expected GPA to be comprised of a dozen or more X Altec employees. I have spoken with Bill on a few occassions and found him most accomodating and knowlwdgeable.
Every time I see his new components I think it is time to move from my Vintage groove.
Please give us some insight as to the comparisons you have found between old and new drivers. If anyone could possibly preserve tradition I think it would be Bill at GPA.
A friend Dave WOJO who also is a member here has wonderfull things to say about new GPA offerings.
Could this be the vintage gear of tomorrow?

Gary

[spkrman57]

Most are identical except for some later drivers that were more driven by using only 4 types of magnets(EV's decision) whereas Altec used 12 or so different magnets.

Bigger magnets do not always mean a better driver.

Bill modified some drivers to bring them back to the orignal specs.

Naming conventions for the drivers have changed only due to legal copyright issues as Bill has some original equipment to make the drivers the same as the original Altec drivers.

Altec is a company owned by overseas folks and about to be merged again(seen on this forum last week)!

Hello,
After consulting with the manufacturer of auto-transformers, I add an L-Pad to finalize the settings.

Stéphane :hmm:

[JoMoCo]

Stephane, would love to hear your comments of the evolution in sound improvement / changes... between your current version with its different components and first versions which you changed & moved away from...
Thanks in advance:drive:
Jon

[stephane RAME]

Hello,
The first version of the filter was advised by the LDA which store my advisor for this project.
The second version was the first test with theoretically more efficient components, capacitor paper, autotransformer, large self induction, resulting in an improved low-frequency area, but less good in the high frequency.
The third version brings improvements in the high frequency but a high level problem, his uptight.
The latest version fixes the problems high level, but requires a move up a notch setting the autotransformer.
In summary, between the original and the latest version, improving the overall transparency, enhanced with more material in the low frequency, high-level improvement in high frequency.
Best regards.
Stéphane ;)

What would you think of substituting a Fostex R100T instead?...I checked out the ebay store link but it does not look set up to sell internationally to the USA? They seem to be approx the same price excepting the 1dB rotary dial on the Fostex...I don't know if the more generally availible 70volt or 25volt transformer attenuators would be applicable here or if they have the sound quality needed. I wonder what Shindo uses on his HF field coil drivers?...
Thanks Jon

I see they are made in the UK...... does that mean they they were actually made by Vitavox, or did WE actually have a factory over there?

Very Nice Stephane :thmbsup:

You've effectively built a modern version of the Westrex 20/80 System ( though I like the looks of yours much more ) .

In your opinion , which of these two horn types gives you the better imaging ( Acoustilens or the GPA 6040 ) ?

>< cheers :)


ps 1 ; here are 3 examples of the original woofers ( courtesy eBay ) . ;)

- Obviously, technology licensed from Altec ( I hope W.E. actually paid ) .

ps 2 ; I like your solution for mounting the lens without drilling holes into the vintage metal .

Following ETF 2009 which allowed me to listen to my speakers in a different room instead of home, and due to some advices, I decided to purchase used JBL 2402H. Those tweeters have the same specs as the GPA 399-8A wich simplified the filtering. I hooked them up on the RCA MI-9472A autotransformer which attenuates the GPA 399-8A with relation to the 515-8G.
The filtering is made only with a 1.5µF for a 6dB rolloff, the listening results is a more "aerated" sound due to the extended high frequency response, thus making some details appearing.

Pas de problème Stéphane, ça fait toujours plaisir d'aider un compatriote :)

I would ditch the bi-wiring. It is a waste of wire and I would flush mount the woofer from the front of the cabinet to reduce unwanted diffraction.

Bonjour Stéphane,
superbe boulot, j'aimerais te poser 2 questions:
1/ j'ai acheté récemment des 2405 jbl qui ont la même plaque de fixation que les 2402, je les pose aussi sur l'enceinte, mais as-tu essayé de les baffler comme le fait JBL?

2/ quel bénéfice a apporté le blacksonnage du pavillon Great Plains? j'ai des 511 altec dans un coin et je me demandais si cela valait le coup.
Cordialement,
Jean

[stephane RAME]

Bonjour,

Je n'ai pas fait d'essai de bafflage, il sont juste positionner reculer par rapport a la facade a l'aplomb du 399 (les 2 moteurs sont alignés).
Le bafflage sur le 2402 permet de le faire descendre a 3500hz.

Le blackson permet d'eviter les resonnances mais attention l'effet ne vas pas etre le meme entre le MRII564 qui est en resine et le 511 qui est en aluminium.

Stéphane

Hello Stephane,
great job, I ask you two questions:
1 / 2405 I recently purchased jbl which have the same plate as 2402, I put them also on the premises, but have you tried to baffle as does JBL?

2 / what benefit has brought the flag blacksonnage Great Plains?
I have altec 511 in a corner and I was wondering if it was worth it.
Sincerely,
Jean


Hello
I did not test bafflage, it is positioned just back from the facade has the aplomb of a 399 (the two engines are aligned).
The bafflage the 2402 lets him down a 3500hz.

The Blackson can avoid resonances but beware the effect not going to be the same between the MRII564 which is resin and the 511 is aluminum.
