[QUOTE="jmanpc, post: 2565186, member: 565915"] So I was driving along, on the mind-draining 16-hour trip from Jacksonville to Arkansas. I was pondering about what one could do to protect subwoofers from blowing. I started thinking about how a driver with a hot voice coil has a higher resistance than a driver with a cold coil. Which got me thinking- what if there were a device that was sort of like a passive crossover, that kept constant track of the coil's impedance. Once the driver's coil reaches a certain resistance, the device would either cut or reduce power. But that led to more ideas- What if the device had a digital interface that allows the user to set the impedance at which the driver is shut down, the impedance at which it is turned back on, etc. It could also have RCA inputs and outputs that would allow the device to make the overheating driver quieter, rahter than shutting down. It could also insert a voice message like "Your right front tweeter has reached its thermal limits and is being shut down." And if it has RCA inputs and stuff, why not have it be an equalizer or an active crossover.... the possibilities are endless. It could come in several models- from a device that just allows you to set an impedance for a desired driver to something that can control a 4-channel and a mono for a subwoofer...
