Banga Posted June 8, 2020 Report Share Posted June 8, 2020 Hello all This is my first post on this forum. I am a audiophile passionate about vintage and I bought two pairs of Acoustic Research AR-2ax speakers, in the two variants, the one with textile suspension and the other with foam suspension. I would like to start by changing the capacitors, both pairs still having the original capacitors. But here, what I read on the forum is somewhat contrary to my practical experience. I noticed that most of those who did this operation recommend changing the capacitors with MKP, polypropylene. I tried this with other pairs of vintage speakers and the sound was metallic, synthetic, similar to the sound of modern speakers. After multiple tests with MKP, MKS and Electrolytic Capacitors, I came to the conclusion that it sounds best with the same type of capacitors they were built with. The AR-2ax speakers, from what I read, have two bipolar capacitors, 6 uf on medium and 4 uf on highs. Has anyone tried to change them with Electrolytic Capacitors, but of good quality, for example these?https://ro.mouser.com/ProductDetail/Vishay-Sprague/TE13021-E3?qs=j607B05hb73s9DH29bJsfg%3D%3D Thanks and excuse my English, I'm from Romania.
