I like to imagine Edison was disc sound reproduction because Tesla wasn't and he could finally get ahead of him on something. Anyhow I'm sure we have all seen stacks of those very thick Edison Discs. I usually skip over them as it is hard enough getting a clean 78 nevermind a clean Edison disc. We do have Edison's and Bell's scientist to thank for the playable record.
Here is a rare pic of the Edison Disc in production.
An early beautiful player which appears to convert a cylinder player into a disc player. Very cool.
A couple of months ago I get this email about thinning out some speaker projects from my friend JC in Georgia. He built my Jubilee bass horn clones and SnailTrac bass horns. In the list were his Tractrix horns I've been drooling over for years. This will be the basis for my first 4 way system. He also let me take home some good sized mf tractrix horns. Sunday Stacey and I loaded up and headed for Georgia a 7 1/2 hour turn around road trip so 15 hours on the road but totally worth it.
This is becoming a familiar site as the sun comes up on the way to Memphis. I've been through Memphis more recently than I have in years.
In Mississippi there was a cotton field right behind the gas station. Ledbelly was immediately going through my head.
JC is removing the drivers for the trip home. This speakers are so black they are hard to take pictures of and they just soak in the light.
I had to totally wash out the pic just so you could see the curves of these massive horns. 70hz to 600hz. They use two 12" Eminence drivers which are about 99db each not sure what they are horn loaded. I guess I'll find out.
Timothy Leary in the background thinks it is funny. Hmm I wonder what that large sheet he is printed on?????
For a sense of scale the fc of the horns on top are 233hz. The drivers below are 12" cast frames.
Thanks JC for all the horns.... AGAIN... And Stacey for making the Ga trip with me in one day.
Here is another article from Radio magazine 1934. I am determined to understand how these things work well enough so I can at least do some simple designs. So far simple it has not been lol... Takes a while for things to sink through my brain. That is how I happened upon this article.
Violent Femmes might have been one of the first punk bands I really fell for but were they punk? Always thought they were better musically than most of the punk bands around. I have good feelings about this band. When I was about 14yo the overdeveloped beautiful 15yo girl on the bus for some strange reason picked me to hang out with and would sit next to me on the bus. If someone else tried to sit next to her she would make them move. We would listen to one headphone each from her Walkman and she would play Violent Femmes or Dead Milkmen cassettes she stole from her brother. I still remember her favorite song was Add It Up. Bus driver wasn't amused when she heard us singing it lol.. For me back then home and school life was hell so needless to say I lived for the bus rides home and back. Not sure what happened to her. Anyway I finally got to see Violent Femmes live in the late 90's and my future wife and I were at the same show together with friends. That was our first concert together. It took me many years to wear her down. LOL... The show was incredible. They are still incredible.
This is an extremely rare speaker by De Mars. It was posted at the asylum by MrBlueSky. I'd only read about this speaker before seeing his post. This is all the information I've seen on the De Mars Styrocone speaker which is rumored to get down to 17hz.
Very interesting driver with what looks like Bozak style tweeters.
The serial number is 101 which is likely the first production unit.
The owners of South On Main were kind enough to give Stacey and I the last two tickets to see Pokey LaFarge. It was one of the best shows I have seen in a very long time. Pokey sounded like he walked out of a stack of southern 78's. His voice is just amazing and showed his interest in musical history. The live performance is so much better than their records but still so good. Thank you South On Main for the tickets and amazing show. If you see Pokey LaFarge playing in town just go see it and you are into Bob Wills, Hank Sr, Old Timey 78's, and rockabilly you must check them out.
