Got a few questions about a distributed home audio system I'm setting up for my fraternity (big renovation coming up). The system on the whole looks pretty simple, but I get a little lost when figuring out how power is actually distributed through the system. We're looking to have 4 zones, one pair of speakers in 2 zones (smaller rooms) and 2 pairs of speakers in each of the remaining two zones (large entertainment areas). 10 speakers total.
The way I see it, each zone will have a volume control wired into the speakers (all 8 ohms, rated to 100W RMS), and each VC will wire into some component "X" (autoformer? speaker selector?) which in turn will hook up to the amp. Single source, multi zone, high power. I've investigated a number of things for "X", but I don't completely understand how the power is distributed from the various components. From what I can gather, power distributed to each channel from a speaker selector are P_in / K. I can't find anything that explains how audioformers distribute power.
My question is this: If I want to deliver 50-100W RMS to each individual speaker, what sort of components do I need to protect my amp and other components while delivering this kind of power to the speakers?
A few considerations: It's a fraternity, so it's guaranteed that someone will get drunk and decide they need to listen to Don't Stop Believing at full power. It's also almost certain that no one will understand how the system is set up after I leave, so permanent solutions, or idiot proof solutions would be better (but don't let that prevent you from offering the best solution, I can do certain things to help idiot proof these electronics).
