Having good audio friends in Berlin and knowing their audio community is very active I had to post about Emile Berliner (May 20, 1851 – August 3, 1929)….
This German-born American actually invented the flat disc “gramophone record”…we owe him so much!
Now the Berlin will call themselves Berliners?
Western electric 12a brackets all hand made as usual.
I guess it all started in 1926 when they had to transport the we12a and we13a in the USA from New Jersey to San Francisco. See here they had dedicated truck, task force and even sherif to guard then with his gun!
Check out the image wgere you can see 2 WE12a horns, the WE13a stands and those will be packed with all the goodies…these convoys travelled the country to “demonstrate” the “Talkies”….in the mid 1920’s sound on film was a novation let alone syncronised sound on film…Tell any kid today that he owes his taken for granted “instant video with syncro sound” to these guys…!
This crowd is actually taking care of “high tec” of the age. The cost of this such a syetm was proablly as much as a regular home…
Let’s say that such extreme transport resource is not “really” necessary in this day and age!
The very 1st horns that I made for US west coast were shipped to New Jersey and then taken by truck to the West Coast, same route some 90 years later. The owner of those horns is very proud indeed..
Today’s audio equipment is small, light and easy to send around the planet all neat and snug in some sort of padded protection.
The big horns it’s a whole other story…They do dismantle into sections just as the originals that does gives “some” ease…but still.
My horns have travelled all over the planet.
13Audio has designed dedicated wooden crates that along with use of selected professional and careful carriers insure a safe voyage to any place on the planet. The crates are bespoke and sized so they can can travel by air or sea and are certified ISPM 15
Castings come out “rough” and need machine work….Not much but it makes all the difference. Drilling, threading, surfacing….all so that they fit neatly in place matching the wooden junctions.
A few images of my friends place, glad to say has not caved into all CNC….keep it real in a world of 3D printing….!
A few posts ago I showed a 12a hanging and this is a follow up.
Only one channel now but the second will be setup soon.
I’ll be spending a fair time setting the system up, tuning to get the sound needed. This is truly unknown territory indeed ! We could go for the all vintage xover etc… but I know that doesn’t always deliver the sound that’s needed. Anyway updates are to follow…
Great to see my 13Audio horns in such posture….
I’d really like to know what was going on during the 1st half of the 20th century….
Okay I think that the Western electric horns are not only fantastic at what they are designed to do delivering a level of audio efficiency unheard of but also the organic shapes are just pieces of art….btw that another reason I reincarnate them…
Here we have some train design….did they do this on purpose? Man it’s just awesome to see what they did!
The Cleveland Mercury took to the rails in 1936 and remained in service until the 1950s.
The we13a needs good feet to support the mouth. These are like originals supporting the horn at the exterior sides of the mouth. It’s strange that when you support the 13a in the middle of the mouth it affects the sound. Actually when you listen to a pair in stereo one being correctly supported and the other not you immediately hear the difference. It’s like putting a central tension point. The mouth is 62 inch (157,5cm) side and the wood is about 1″ thick and it’s supporting a great deal of the horns weight. So that kind of all puts a lot of pressure on the centre of the mouth. When supported at the exterior there is no flex at all. 13audio make the appropriate legs to support the mighty 13a.
I was forced to change foundry See here
Therefore it was necessary to spend sometime with the craftsman who’s doing the work, to go over the details and specifics.
Here a few images showing the mould ready for the molten iron. We run a test to then break the throat just to check the regularity of the throats wall. All seems set.
Tomorrow fulls sets will be done for we13a and we12a parts.
Modern glues have made the whole gluing in woodworking easy. Well easy is good I guess? Maybe not in my world. Many only know modern glues, liquid brush on clamp and wait. Others know the old ways. Animal glue. What is that? Animal glue was the most common woodworking glue for thousands of years until the advent of synthetic glues such as PVA and other resin glues in the 20th century. Today animal glue is used for making violins, wood instruments, piano repairs, antique restoration, etc…The glue is applied hot and glue is kept hot in a glue pot that takes a good 45 minutes to heat up, that’s the thing. You need to think ahead and plan your work. No full speed ahead and then open the glue, apply press and wait….nope! Think ahead…prepare and then full speed ahead! Animal glue cools quite quickly and it’s then already a strong bond. Actually 1 minute and you can continue work. That’s the the big thing. It allows a continuous workflow. All that’s needed for assembling the many hundred individual sections of the we13a or we12a. The nails are placed after the animal glue has fully firmed, kind of second level strengthening. You can see here on the Western Electric 13a that there are very few nails, it’s all glued. The secret is also to have very tight tolerances, not easy given the curvatures. In forefront my hotpot for the animal glue. Needs cleaning! I only use animal glue that’s what the craftsmen who made them back in 1926 used. Keep it authentic, no shortcuts and the time and devotion is all worth it in the end.
Here the 1st steps to install a full size western electric 12a and 13a system. Yes that’s 2 x we12a and 2 x we13a for one lucky listener….more as we build this. Next weekend the whole thing should be singing. This is the very 1st home installed 12a and 13a system in Europe, well there is only one other one in the world that I know of…..Silbatone graced us with the 12 and 13’s at Munich some years back.
Here all will be tuned to stay and for playing long long sessions.
I say? All fun….! Yes that’s true!
