My PreSonus Eris E3.5 speakers starting having issues. First with loud sound, then whenever I turned them on.

The click-click-click WUB WUB WUB was not very pleasant. So I took them apart, and found the problem!

My old speakers (PreSonus Eris E3.5): amzn.to/3LVd3DY
My new speakers (PreSonus Eris E5 x2): amzn.to/4bUArvL
My audio interface (Behringer UMC202HD): amzn.to/3ZzpUie

Tools I used for the repair (note: some things you don't *need*, it just makes things easier)

- Hakko FR-301 Desoldering Gun: amzn.to/45wW6Xb
- Hakko 633-01 Soldering Iron Holder: amzn.to/4pYuEsA
- ISO-TIP Model 8000 Cordless Soldering Iron: amzn.to/45zu7G9
- Kester 44 Solder wire: amzn.to/4t5KUuI
- Hakko CHP PN-2007 Long-nose Pliers: amzn.to/46f0UAx
- Dowell Micro Flush Cutters: amzn.to/3YWH7SD
- Hakko CHP PN-20-M Micro Pliers: amzn.to/4akwDlp

And the capacitor that was needed for the repair: 24V 1000µf (I used a 35V 1000µf). This kit has a suitable replacement: amzn.to/4bT0aVs
