It was a treat to go into the PS Audio room as they always bring something special. I’m glad I didn’t miss this room so I could share with the group. When I first walked in the room I must admit I did not recognize the design. One of the people that had knowledge about the speakers in the room told me these were Arnie’s personal listening speakers designed by him. These were on loan from his family. They look to have 8 tweeters from the Kappa .1 series, 2 mid bass speakers, a line array midrange, and 2 12 inch woofers. One tweeter is on the back and a midrbass as well. It was a hodge podge of former lines into one is what it looked like to me. Some parts looked unfinished. It did have external crossovers. The finish on the outside which looked great was a corian type material according to them. I took the best pics I could with my phone as lighting was poor. I also made a video but there are people talking in it which I couldn’t help lol. It was a very busy room. Enjoy.
