For an early model 2ax, I’m looking at these phenolic domes. The domes are relatively heavy, compared to a silk dome, treated silk dome, or thin polyamide dome, or even a titanium or beryllium dome. So I expect a stiffer suspension for this heavier dome. But these well-aged dome suspensions seem to have hardened and stiffened beyond their initial compliance.
In looking at the suspension, it appears the 4 yellow globs are both a suspension and damper. Then over the top of it is a clear flexible sealant, that has hardened. The voice coil is attached to the underside of the dome, in the magnetic gap.
Am I correct? Anyone in here willing to share their knowledge here?
Im pretty sure that my tweeters are being restricted in motion. While I’m getting output, I don’t think I’m getting the full output that was available when new.
I’ve rebuilt many vintage cartridge styli, from cantilevers, to tips and suspensions. I’ve also rebuilt tweeters using various parts I’ve found on eBay. I’ve formulated various room temperature curing elastomers that I use to form new cantilever suspensions for cartridge styli. I’m wondering if I should attempt to rebuild these tweeter suspensions.
