In Reply to: Shunt across speaker terminals? posted by Tweaker456 on July 27, 2016 at 00:16:41:
Walker Audio makes the above for use across speaker terminals. The intent is to block very high frequency noise, RF and the like. I think Al Sekala once figured out that inside is a 10R or 100R resistor in series with a .01uF capacitor. This network does not operate at frequencies low enough to eliminate "hiss". If you want to do that, you could experiment with using higher value capacitors, but I think it would be a trade-off between blocking actual treble content along with the hiss. Most of us, no matter how superannuated, can hear hiss, which means it is well down below 20kHz in frequency, where some of the music also lives. If you try this,I do think you would be best off with an RC network, not just a C.
