J. W. Hall Posted May 14, 2023 Report Share Posted May 14, 2023 New to me AR-4x. Do they look a little different? They belonged to Jim Fosgate, he worked on them himself years ago. Not sure the extent of the changes--just hooked them up for a first listen. They sound great. Quote Link to comment Share on other sites More sharing options...
genek Posted May 14, 2023 Report Share Posted May 14, 2023 These look more like the earlier AR-4 to me. Quote Link to comment Share on other sites More sharing options...

Agreed...I don't recall seeing an AR-4x tweeter with the screen and pad arrangement of the AR-4 tweeter. Additionally, the serial number on the cabinet tag is high enough to be well into 4x production, so it is not likely for these to be early enough to have overlapped with the AR-4. Interesting...

ReliaBill Engineer Posted May 19, 2023 Report Share Posted May 19, 2023 Pot looks different from pics I’m used to seeing. Splined, split shaft? And removable grills? Treated woofer cone? Quote Link to comment Share on other sites More sharing options...

Treated woofer cone? These specimens were definitely worked on by someone along the way. -Removable grills were used on 4x cabinets with (much) later serial numbers than these. It is obvious to see where the original hot glue was removed on these. -The split shafts of the level controls shows that the pots were replaced with L-pads or the pot replacements sold by AB Tech (in the 90's). -It is likely the original 4x tweeters were simply replaced with AR-4 tweeters. Cabinet hole dimensions are the same for both models Roy Quote Link to comment Share on other sites More sharing options...
