Menahem, it seems you have still not understood the meaning of the words coupling and decoupling capacitors. Coupling capacitors couple AC signals from one circuit to another, but block DC (read Martin's post again). Decoupling capacitors are for GETTING RID of UNWANTED signals from a circuit. This is usually the case in power supply lines. In audio

[quote user="chartz"] Yes, this wasn't very nice at all. People here are sharing their knowledge and it's free. We are all glad to do it! [/quote] Unfortunately, in this case he was not spreading knowledge, but total nonsense. It is totally against signal theory and his "advice" will at best cause disappointment, when followed

Thanks Martin for taking the time to explain the facts once and for all!

[quote user="fagaldi"] Today, with the advanced technology of film caps (Wima MKS2), you can quite easily use a 2.2uF Wima cap instead of the original 50uF (or even higher value). I've routinely used Wima 3.3uF as a substitute for an electrolytic 220uF. And the Wima does a better job of blocking the DC. The much smaller value means even

You can never replace a capacitor with a much smaller value. That would most certainly cut the bass. You can replace electrolytics with polyester types if you want. Or you could replace polyester with polypropylene if you're a real purist. By the way, it seems some of you routinely replace the tantalum electrolytics. Why exactly? They don't

[quote user="Søren Mexico"] Surround foam is made to reverse to original shape whenever in rest, with 2 different fixed positions it can never do that. I dont think this will do any difference in sound, but maybe it will cause the surrounds to brake at an earlier time than if fixed in the correct way (shimming). This is just my thoughts

Now both CX100 are done too. As far as I can tell, both work as they should and certainly sound very good. Many thanks to Craig for the tip about usig a battery when centering the cones. This worked flawlessly every time for me. I never had to readjust after applying the clips to the surround. This made the work quite straightforward, eventhogh you

Now the second CX50 is done and it works as well as the first. Here is how I did the work: The speaker, as I received it. First I removed the woofer from the cabinet. The outer edge of the foam roll edge was cut off with a knife. Then I removed the inner edge from the paper cone. The remaining black goop must be carefully scraped off the cone with a

I have now connected the loudspeaker to my Beomaster 901 and listened carefully. I used a synthesizer and a drum machine to get "pure" sounds but I also listened to the radio. When playing a sampled electric bass, there was a slight buzzing now and then. The strange thing was that the buzzing often stopped after a second and if I played the

The rest of the edge is glued now. Tomorrow I'll be able to listen to the result.
