twinsig Posted July 27, 2022 Report Share Posted July 27, 2022 I restored a pair of AR2ax's and seem to have a buzzy mid, and seems to occur in specific freqs, mostly on some vocals. I'm trying to find how to test, investigate and identify the problem. Any methods out there? Anything like audio tracks on CD? Installed are HiViQ1r tweeters (RoyC mod), OEM pots in really nice condition, new caps, etc. EDIT: I DO have a BK Precision function generator.

Assuming your signal wires are connected to the 1 & 2 posts on the speaker, disconnect the jumper that connects post 2 to post T and play your speakers. I you still hear the sound the problem is related to the woofer. If not, then the mid. In the 2ax almost all human voice originates through the woofer, with mostly harmonics in the mid. It might be wires touching the woofer cone. Just a guess. Quote Link to comment Share on other sites More sharing options...

As with over epoxied large advent woofers, the same in all pre 9 series mids, and any other unpleasing external dampening ugliness ....i removed the grills, replace with very white insulation( same exact, same amount used). With clear epoxy, increasing the aesthetic of their signidivicantky. I have so many,(all specs, is be happy to give you set for shipping. Not much resale anyhow. Truly I ha e a ton, glad so some could use. Quote Link to comment Share on other sites More sharing options...
Knervie Posted September 11, 2022 Report Share Posted September 11, 2022 Any chance of getting a picture of one of the cleaned up speakers ? Maybe with and w/o the grills ? Quote Link to comment Share on other sites More sharing options...
