Done‼️Convert Westrex T530-A to JBL 375 With Beryllium Diaphragm ||The Most Tunable Driver Very Rare

Alhamdulillah
Thanks to Allah
Thanks to My Team work.
Thanks guys.
Thanks to Subscribers and Viewers.
Lucky to be able to make documentation of this historic Driver.
Westrex T530-A This is a driver developed and commercialized by Bert Locanthi during the JBL days. Made by Lansing at the request of John Frain of WESTREX.
JBL 375 To add to historical data, the JBL 375 itself was not a Jim Lansing design, but the JBL 375 design was derived from the Westrex T530A SMA horn unit manufactured by JBL on behalf of Westrex in 1953 (similar in appearance and design to the early Model 375 gray unit which are nearly identical).
Westrex T530A itself is an enhanced design of the Westrex 594A. While everyone else has the same 4-inch aluminum Voice Coil wire and aluminum film design, the Westrex 594A is a line exciter, while the Westrex T530A is a line cobalt (Alnico) magnet.
The Westrex T530A was published in 1953 and launched in January 1954, while the JBL 375 was launched in April 1954.
So you could say the Westrex T530-A is a prototype of the JBL375.
In this video, we are trying to repair and upgrade from the T530-A to 375.
A significant difference is found in the Tube Horn throat, which was originally Pvc to Bronze Brass.
While from Diaphragm which was originally aluminum became Beryllium by (Radian).
Enjoy watching, hope it's useful.

Ga nyesal liat videonya abang sunggu profesional

[@kevinchamberlain7928]

Old School quality is wonderfully high, and robust! Built forever! So glad these artefacts were saved, restored and even upgraded! Would love to know what they sounded like new?

[@crowblunt536]

I'm impressed of how much work to put it and restore it just to make it sound beautifully good

[@untungtruzbejo2235]

Sungguh bahagianya org jakarta. Tak sia2 dari vietnam. Semoga semakin sukses, mas.

[@you2ber252]

WOW! What a work of art... And I can barely imagine how fantastic they will sound when properly horn loaded!

[@dennyturang3961]

sungguh pekerjaan yang luar biasa sangat profesional❤❤👍👍👍

[@rann7665]

sampean memang benar2 jenius...

[@ghanighani9561]

Cermat sekali kamu bikin,kasi hp nya bolih,untuk pertanyaan,speaker yang mau di beli.

[@pablohernantoledo9463]

Hola gracias por compartir, excelente trabajo, cuanto compromiso y amor.

[@paw45]

This is my first time to see a driver of this type.

[@matrixcompt1117]

lungguh silo kro nyruput kopi cangkir cilik ... sedep maaszzehh ..

[@electronicshelpcare]

great driver unit

[@riitechmadiun4428]

very detailed workmanship 👍👍

[@cleversonkloster6222]

Parabéns ótimo trabalho obrigado por compartilhar

[@remaca]

Expertise, workmanship, attention to detail and generosity to share all of it. I appreciate and thank the channel owner for his dedication to his work and for sharing it. One last comment: it wonders me that a person in Brazil can learn and appreciate the work of a craftsman in the other side of the world! Thank you!

[@Oso136]

Hermano gracias por instruirnos👍👍y por enseñarnos a reparar estás joyas 👏👏👍👍🙏🙏🙏🙏🙏. Qué buen trabajo

[@gregvisioninfosoft]

Great work. I see you do all aspects of the restore. Fantastic! But what about that high resonance new brass piece you put in - as opposed to low resonance plastic?

[@broosky333]

Wow. I was not expecting to see a full compression driver disassembly. My only question is how do determine how much to magnetize the motor?

[@BjorgenEatinger]

He read the amount before demagnetizing.

[@weatheranddarkness]

I'm quite certain you can't overdo it. The objective is a saturated voicecoil gap, and the materials and geometry of any given motor assembly will define the maximum strength.

[@DesignVisStudios]

i retrofitted my Pure audio project horns with eminence n314x Textreme compression drivers and tuned it with dirac... works well.

[@jboy117]

LE15A、375とHL99、075を組み合わせて使ってました。懐かしいな～375ドライバー。MacintoshのC29、C33をプリアンプとして使っていました。パワーアンプは、パイオニアのエクスクルーシブのM5a

[@nigelm.steele9329]

Great restoration

[@UmerFarooq-nq4du]

I'm a big fan of your work love from PAKISTAN

[@csj9619]

That is a monster compression driver! 2" throat and 4" diaphragm? WOW! Looks like a Western Audio or Altec Lansing from the 1950's or 60's. Nice score bro.

[@mariodesantis8747]

Ti faccio i miei complimenti, sei bravissimo un fenomeno, vederti all'opera è un piacere. Grazie ciao. Mario da roma.

[@yogaswara703]

Mantap ... Hampir sama dengan twiter serwin vega jadul dan vivey jadul

[@realcygnus]

Nifty AF ! I didn't even see a coil ! Can anyone briefly explain how they work ? & what were those concentric/slotted rings all about ? They sure don't make'm like that anymore !

[@azaz9911]

Через эти прорези и выходит звук .в центр динамика . По окружности мембраны что он новую поставил и идёт обмотка катушки .

[@timoterror788]

Very nice work! I just got crazy when i saw the new Berillium diaphragma - these must cost a lot - damn! 😲😲

[@motorheadbanger7720]

That's a great job congratulations

[@LabArlyn]

Wih sangar Berry Lyum driver. Speaker sultan tuh pasti.

[@christopherleubner6633]

This was a complete overhaul, excellent job. They sound awsome naked, but put some radiators on those and it would be absolutely awsome. 😁❤

[@MasBRo-ir9ws]

Mantap👍🏻👍🏻👍🏻 jossssss

[@randomhuman1965]

beautiful work I can't believe it

[@275jesuss]

Saya terkejut bahwa ada mesin yang bekerja dengan mendemagnetisasi dan remagnetisasi. Pengemudi ini sepertinya menggunakan part yang rentan terhadap guncangan internal. Fan/🔔o)))

[@andrewdenine1685]

Nice job sounds fantastic

[@tubeelectron13]

It’s very better with JBL aluminium diaphragm 😆👍

[@dimasputra3686]

Bnr2 detail...success trs mas

[@johnwolff4743]

Very nice detailed workmanship. Why did you not add adhesive to Throat? Why not use the authentic Materion Bex 4016 Diaphragm?

[@MPOMusicPartnersOrganisation]

RADIAN is a very good component O.E.M aprouved by JBL as a reference.

[@pomnichowski]

Spoko... very pleasurable to view... many thanks...

[@sandipsirsath5940]

Nice work 👌

[@teguhfirmansyah738]

Mantap Om.. Mau tanya kalau service spul tweeter mobil bisa jg Om? Kalau bisa ada nmr kontak nya Om?

[@RaymondMDay]

If those are wax plugs in the screw holes you could have just applied some heat to get those out a little bit easier..edit.. After watching longer.. I see why you did it the way that you did... that said.. this is some incredible work ..how you fixed those hold down bolts I have never seen that done before that was so cool.. the instrument that you hook them up to.. with the voltage.. what does that do?

[@peterlarkin762]

The instrument is using electrolysis to coat the bolts/binding posts with nickel or something.

[@nathanieljames7462]

Magnetizer/de-mag

[@direwolf4849]

Black wire to negative (-),red wire to positive (+) , apart from that good video

[@kalomeon]

Yes, vague speaker designs are always welcome :)

Excellent work.

[@marscellkudus]

keren sekali mas... pengetahuan mu tentang speaker kelas dunia... sukses selalu mas...

[@pietrochianese9308]

Lavoro ad arte ❤

[@GeorgeGeorgalis]

Nicely done! For sealing screws, try Mastic Gum (Chios Mastiha).

[@kennethjackson7574]

5:58 Ah, that all-to-common tool: the prydriver (screwdriver used as a prybar)!

[@BigElCat]

Not sure the titanium diaphragms in my Klipsch Matrix horns are conveying all the beryllium / JBL subtleties, but those sure sound like the trumpet they're playing.

[@WayneMickel]

Great video

[@alicemoon9008]

Great Job 👏 - Hi 👋 from Russia 🇷🇺 ….. Chertanovo Chopper’s Custom Club ….. (Moscow City 🌆)

[@momar678]

I'm sitting here thinking "how is this guy not messing everything up exclusively prying on things with screwdrivers?" Then I saw the description.

[@Mooseslife]

Beryllium dome. Isn't that a dangerous product. I know it is the dust from it that is bad. I just don't think I would use it, but that is just my opinion. On another note. Absolutely great work on the restoration. Good job. I would love to see them with horns and hear them again. Have a good day.happy

[@florin604]

What dust?

[@wombatillo]

You're not supposed to even touch it by hand let alone breathe any of it. The reaction to beryllium is unpredictable, often slow to develop and depends on the individual. I know he's not touching or modifying the diaphragms but damaged ones could leave fragments and dust of beryllium lying around. In those cases it would be very bad to shoot compressed air into the speaker components and blow that dust all over the place. Beryllium especially in the lungs is not very nice. Transistors with BeO insulators and x-ray tubes with metallic beryllium windows have pretty serious warnings about not messing around with them.

[@laurentsanterne7231]

beau travail !! par contre a la fin de la vidéo a la fermeture du deuxième il y a une inversion de polarité le + et le - pourquoi ?

[@lunchboxjoeb]

these look like giant car audio tweeters of today ... thats nuts

[@michaelfoort2592]

Yang paling bagus

[@jakoblindekilde5832]

Impressing job! -As always

[@SatriaSpeaker]

Thank you ♥️

[@janhartanahartana43]

SUKSES SELALU PAK. THANKS FOR SHARING

[@SatriaSpeaker]

You're welcome

[@MrXjoeharperx]

These must have been incredibly expensive when they came out.

[@kitchenbriks3685]

My favorite part was all the bugs running around.

[@rustybergman3708]

Thats sounds amazing so beautiful

[@dandywardana6702]

Malang Hadir Mas Eko 🙏🙏🙏, lama tidak upload video di KZbin, sukses selalu buat Satria Speaker 👍👍👍👍👍

[@SatriaSpeaker]

[@farhanbadru3671]

Mantap mass. Bisa nih buat main2 hifi classic

[@weatheranddarkness]

the state of that screw at 1:48 is truly upsetting

[@phillipkeith5565]

Not sure if they make these anymore but they're repairable on day

[@phillipkeith5565]

Precious creature humming The Neighbourhood

[@brian-ze7zo]

saran sih pakek sarung tangan yang item lebih bagus

[@phillipkeith5565]

Best sound on Earth anyone would ever hear huh

[@EnpuerKT]

No body is talking about the massive Beryllium diaphragm. That’s gotta be $3,000 alone.

[@Fahma-nz3qd]

Perfect

[@interesnie-novosti]

You made a mistake, incorrectly connected the wires red to minus.

[@wYatt121509]

Beautiful!

[@rodericbest7667]

Why didn"t you use a thread lock on the screws.?

[@Dmitry14region]

Amazing sound😯

[@SatriaSpeaker]

Thank you

[@phillipkeith5565]

Look pristine

[@chiwahwah2]

welldone

[@eduard1359]

Nice 👍👍

[@ajf9880]

If you don't demagnetize it, you can't open the driver? I have to fix an Altec, but I don't have that machine, how can I open it?

[@fubartotale3389]

Are these compression drivers?

[@richpayton7162]

What horns or waveguides will be used on these drivers?

[@Z-Ack]

Only genuine hand selected oxen horn that are cured inside a moisture free vessel under full vacuum of 2 atmospheres for 5 years in pitch black then slowly plasma coated with pure quartz and acclimated to the specific climate where its going to be attached and used in. Then finally adding the hot pink spray paint before attaching..

[@kekkek7888]

They sound like tweeters but not really, what is their frequency range/response?

[@muhammadhendra4949]

Maaf mas satria saya mau nanya apakah ada perbadingan suara jika ada perbedaan spul contoh nya spul 2 inch dan 1½ inch 🙏🙏🙏

[@andyvan5692]

interesting, but was wondering at 2:14 why you didn't just call in the bomb squad, to diffuse this?- it looks more like a part of a munition that anything to do with a speaker (modern day ones are foam and sheet metal).

[@MPOMusicPartnersOrganisation]

Respect.

[@Matrix...777]

Berylium - best

[@artysanmobile]

Frightfully expensive diaphragms.
