Well, The Gold's are not as neutral from my understanding as the silvers..And they are probably way more picky in the application.. The bass is Excellent with the silvers in a Preamp I can tell you that.. However I would not use these exotic caps on the Bottom end of a speaker, in other words the woofer section, it its a 2 way then Maybe just use a better bottom end cap and bypass with a small mundorf, if its a 3 way then take them off completly from the bottom end. In Mids and Tweets they are in the top of the class.. I would pull the caps from your woofers if in fact you used them in that location on your crossover, You want bass go with a Cheap Solen fastcap or something in that position, This is In my opinion, but that does not mean I am right. I used solens with the best results in bass heavy drivers however in my experience. I would honestly look at what they did to your speakers and change them first, I doubt you cut off much in the electronics.
