Has anyone messed with biasing capacitors in loudspeaker crossover networks on these forums?
In the link below I did a study of the effects using Solen Fast capacitors. The bias is applied a the centre node of two series connected capacitors and using a 9 volt battery the voltage is applied via 2.2Meg ohms.

The folks at JBL seem top swear by its virtues and while I can vouch for it making a difference frankly it does not make a silk purse out of a sour's ear..at least with my equipment (Passlabs).

Biasing does appear to improve performance of mylar and bypassed mylar capacitors and perhaps in this instance biasing a cheap way of improving performance with budget parts.

Although comparisons the ICW SA Clarity capacitor was audibly superior by a significant margin.

I experimented with biasing caps for my tweets and was very pleased with the results. It also seemed that the more voltage I biased with the better it got. I wound up clicking a bunch of 9V batteries together for a total of 100 or so volts. I was using 600V polypropylene caps.
