fiogf49gjkf0d Hello to all, After following the comments of Romy for some time (have learned a lot, thank you), I would like to ask a question on this subject.This circuit is built with resistors, diodes and capacitors. Could someone elaborate how it can produce a smooth curve by "cutting" the current in discrete values ? it looks a bit like an AD conversion, how does a smooth curve result from this ? The before-curve shows a sinus with a clear interruption - then all other horns should produce terrible distorsions, am I wrong ?Avantgarde claims they use only 4 passive elements for the complete system, how is it possible looking at this schematic ?Regarding these horns I have a second question : they use ABS. I heard them and the sound is outstanding. How does ABS compare with glassfiber or carbonfiber ? I heard that these materials can resonate. Does anyone have experience with this ?Thanks and br Mark

Mark, the Avantgarde circuit is idiocy. I initially did not get what it was but now as you mentioned it I looked again and realized that there is no DC source in there! The DC-bias caps are a very good thing, I used it many time and there are unquestionable benefits. The Avantgarde does not use a DC buttery and other would do but they decided to rectify the sound single and use the rectified DC for cap’s bias. How stupid nigh it be? It is not to mention that it was made is acoustic system that costs many dozens thousand dollars. Ridicules!!!!
