Yeah, the title says it all. I do respect JBL as a serious, reputable speaker manufacturing company, but biasing non-polarized foil capacitors by applying some DC voltage strictly resembles marketing BS for audiophools :rolleyes:. How should it work? Did JBL perform DBT's to substantiate :hmm:? And what happens if the (negative) signal peak voltage exceeds the (positive) bias voltage :blink:?
Best regards!
