I have a subwoofer by Polk that is a perfect example of garbage. It’s designed with a standby mode and will turn on when the amplifier senses a signal. Well this thing is actually on all the time drawing electricity through 2 crappy capacitors with low tolerances. Over a span of time these capacitors heat too much and eventually fail, leaving the owner to junk the whole thing and start anew.

This thing was designed this way on purpose. If you go online you will see some of the owners who know better will replace these capacitors for less than 5 dollars to bring them back to life.

This is what happens with a lot of devices. They plan them to fail just like this. It’s a racket.
