Hello Tosh, The two 15mfd are not parallel. One is film the other is electro.

Thanks Tosh, I have newer subs, and also my XO look different that the ones on your img. Here is a few pics of my XO: Any suggestions for this^^^ 330mfd Any suggestions for this^^^ 15mfd Any suggestions for this^^^ Any suggestions for this^^^ Thanks, Carlos

Thanks for the support. I have done some reading about capacitors. I was hoping when I started this thread to get some suggestions from SL3 owners that have done such an upgrade. I am just looking for what some other owners of SL3 have used as far of upgades to their XO. Anyone? Thanks, Carlos

Tosh, Thanks for the input. I did not mean to make you uncomfortable by my ignorance on capacitors. I am a newbie at this, however I am very comfortable soldering and also doing some ultrasonic welding. I am just getting into it. It is my second set of crossover upgrade, and after my...

Ok, so I figured out that I have to replace the electrolytics with same and film with same. So, now I am just looking for advice on what type of Caps to get: 1) for the Richey electrolytic 330 mfd=? 2) for the Elpac film 15 mfd=? 3) for the Richey electrolytic 15 mfd=? 4) for the Richey Not...

Ok so I solved the issue with the Voltage on the capacitor. Now my last variable is that a couple of the capacitors seem to be directional(electrolytic), mainly the one closest to the bottom of the board closest to the speaker wire junction. The is another one in the middle that seems to be...

Thanks Jonathan. I am staying in the passive side. My biggest issue when selecting capacitors is that all the capacitors on this board are rated at 100 VDC, and some people are replacing them with 250 VDC ones. That part is screwing with my limited knowledge of electronics. I figure that while I...

Thanks for the info on the panels. My biggest task has become the capacitor upgrade. There are a series of 4 capacitors, 3 are made by Richey. From the speaker terminals going up the first one(Richey) seems like a film 33 mfd at 100vdc(what is a suitable replacement for this one)? The next one...

Hello All, I am very happy with my SL3. I recently found a almost new set of panels for them from a user here. I have done most of Gordon's tweaks. All is sounding great. Due to their age, I want to replace the capacitors and have search all over this site and can't find help on this...

Welcome! I am also a new to Martin Logan. I have ESL and loving life. Gordon is a great guy with tons of knowledge. Enjoy your new venture. I am in Eatonville,WA

Thanks again all and specially Gordon. Well I spent 2 days cleaning and preping my SL3 for some cleanning and upgrades. I followed the road kill advice from Gordon, and wow it makes a huge difference. Cleanned my panels really good(no shower) they are sounding well. Put everything back together...

Thanks for your reply Gordon, I will look for road kill instead of dynamat. Also, I was mistaken on my pre-amp, it does have 2 sets of outputs however here is my story, thanks:I am very new to this site and to audio componets also. Have an issue and don't know how to deal with it. Here is my set...

Hello All!!!!! I finally got some decent speakers. I have purchased a mint SL3. They sound incredible, the staging, separation and detail are phenomenal. Prior to this I had Polk SDA 1c, and let me tell you these sl3 are no comparison. I have no issues with them, however I am planning on doing...
