50's Stephens TruSonic DIY Cabinets

I helped my friend Tube Hoarder get some excellent early vintage DIY Stephens TruSonic cabinets moved in. The first cabinet was a Klipschorn style using the 103 in the bass bin. Klipsch used this same driver in the early days. The multicells were so cool we left the tops off.
Stephens early gear was extremely high quality. Check out these pics of the cells drivers and crossovers.


The attenuators will be removed.

These crossover modules are just beautiful. 
Wow... 
Crossover points 600 and 5000.

It was a real treat to get to listen to these 50's time capsules. We didn't change anything just hooked them up and listened to them. They didn't disappoint. If you are lucky enough to have these early Stephens drivers in working condition I am jealous... 
Beautiful sound. 
Beautiful design.


Here is the other cabinet with my friend Tim for size reference. It has the same drivers and horns but different crossovers. The logos are different and the bass bin crosses at 800 and 5000. We are assuming that one was put together and then stereo hit and he built another. This cabinet is beautiful!
Here you can see the loaded the tweeter under the mid range driver.
The crossovers have different logos than the others. If anyone knows which was used first I'd love to know the time frame on these.

I will be posting more on these multicells and drivers later.

Nice little prototype.

Matija Blažičko - Emanation

Check out this wonderful art installation in Croatia featuring tractrix horns and battery powered amps. The artist Matija Blažičko sent some pics to use for Retro Hi Fi Girl Friday but I thought it was too cool for that. Featured in the pics is his sister. Her site here.
From the Artist.
The work Emanation was exhibited in june this year in the chapel of saint Rocco in Zagreb, Croatia.
It was my humble attempt to recreate feeling of big cathedral in small chapel. 
There was Benjamin Britten's Festival te deum played, It was all about the experience of hollographic imaging and stereo separation (I got inspired by the Chesky records ultimate demonstration disc)
Main horns follow tractrix curvature and are made of "artificial marble" composite. They hang freely in the air by the kevlar strands. Frequency response extends below 80Hz but are digitally crossed over at 80Hz from where the pair of hidden subwoofers take over. Amps work on battery banks so the problems with "dirty" mains are altogether eliminated.




Check his website for future updates.. 

I'm sure the artist would love to hear feedback from you.

Beaty In Sight As In Sound - 1957

It seems this article was born out of the growing pains of stereo. Should I build two houses since stereo requires two of everything..... Yes...
