OMA The Back Story – Part 3: Ground Floor Construction



Oswalds Mill Audio. A strange name for an unlikely story.

OMA gets its name from a more than 200 year old mill in Eastern Pennsylvania, restored by OMA founder Jonathan Weiss. In that mill Jonathan assembled an impressive collection of vintage cinema and studio audio equipment, especially horn loaded loudspeakers, dating back to the 1930’s. Within the walls of this massive mill, Jonathan’s audio obsessions attracted like minded people who congregated there every year for an event which became world famous. This underground community of speaker and horn designers and builders, tube audio and vinyl and tonearm experts became the foundation for launching a whole new approach to high end audio: OMA, Oswalds Mill Audio.

  1. One giant historical peice of furniture. So damn cool .

    What do you guys think of OTL amplifiers and high resistance coil speakers??? Would make for a very pure use of triodes and low inductance high grip coils full ranges?!

  3. Must feel good to preserve such an amazing building. We just saved a 100 year old home up here in Canada, basically lifted the entire building and poured a new foundation. The house sat on the same Jenga blocks or Cribbing you have for 6 weeks while the work was done. We never moved out during the renovation. Also added a 16’x20’ music room off the back. The house was built in the 20’s by one individual over the course of a year. I like to think he was looking down and proud his hard work will live on another 100 years. 🙏

  4. Jonathan – Thanks for sharing this project! Its therapeutic for me – audio is part of my lifestyle and I also started an old building project in Pitt-PA (1/10th your scale omg). I look forward to seeing who finishes first, haha. Oh, its not about the completion, its the process – agree! Really appreciate your content. Thanks so much. John

  6. This series is so cool! Thank you for sharing this journey with Oswald's Mill. I walk past an old mill's ruins daily on my 8 mile hike on Sope Creek in Atlanta. I always try to image what it must have looked like. I can't wait to see your vision unfold for this structure.
