1930 Loudspeakers and Pick-ups

Saw these in Wireless World and couldn't stop looking at the big square horn. It reminds of that big sqaure Voigt horn but this oneis exponential. Tonearm looks like a record shredder. Good stuff.

New Three Way Horn System In The Works

I've been collecting parts for this for many years. This may be the slowest project I've ever done. My friend JC designed the basshorn, provided the math for the builder of the tractrix mid and tweeter. I need to build top hats for these and my least favorite part the passive crossover. Fortunately my friend Chris is helping me with this or I'd have to go active. 

Here we have the bass horn. It is large and can accomodate 12" 15" or 18" drivers. For this application we are using 12" drivers. These will play up to around 350hz.
I am a toddler when it comes to putting systems together but the main point in DIY is to learn so if it doesn't work try and try again.
I need more stuffing. 

 Fortunately these drivers can pick up around 350hz. These are JB 2482 drivers and are so very heavy.
 They will be mounted to these pure tractrix horns. They do look better in person not sure what the flash did here.

 Most of these horns are on loan to me but will be fun to try out for a while. Round tractrix with B&C DE250. They start breaking up past where I can hear lol....
This will be going together soon and then tweaked until it sounds right. That will likely take a while. This will be my second system on the other end of the house lol. Now to find technology to stream audio in sync to both systems... Anyone have any suggestions?

AT&T MW Horns

These were the last of giant MW lenses or horns or whatever they are removed from the AT&T building in downtown Little Rock. These were definately microwave use but they are horn shaped. What flare did they use?
I'd like to use them as acoustic art piece but will likely end up as scrap. Sad...
Abit of local history.
AT&T history that has been watching over Little Rock for 50+ years has come down. In 1951 AT&T started an ambitious project to connect the country with 107 radio-microwave towers at a cost 40 million dollars, 375 million in today’s terms. The project was completed and connected the country with telephone and television transmission. With the advances of fiber optic technology, we abandoned microwave transmission. From what I can surmise this was the last array of microwave towers in Little Rock. These were located on the top of the AT&T Tower in Downtown Little Rock at the corner of 8th and Louisiana.

Custom Four Way Horn System

This four way horn system made an appearance on craigslist of all places. The price was under $20K. The custom horns look great and drivers are JBL and TAD.  I wish I had better pics as craigslist scales them down.
