Unfortunately, while they may be well intentioned, the sales people at most mass market are not well trained. They often only partially understand the principle they are discussing, and as a result, often inadvertently give out a lot of misinformation to trusting customers.
...Now this brings up an additional question.... when trying to pair up a set of speakers to a receiver, it sounds like looking at speaker wattage handling against a receiver's per channel wattage is not a good way of doing things. Is the wattage handling of a speaker and the per channel wattage a receiver even on the same sheet of music? Or am I applying something that has nothing to do with the other?
I pay no attention to speaker wattage handling. It's pretty useless, and most likely a product of lawyers trying to protect their companies from claims due to outlandish abuse. The only one worth considering is the minimum
requirement, as far more damage is done by underpowered amps than by "overpowered" ones.
Unlike with amps, there is no standard for how the speaker ratings are developed. You can't really compare one speaker to another based on them. And trying match them to the amp's output is an exercise, nothing more.
guys at the store recommended higher wattage speakers, but it now sounds like even those can be blown with this same receiver at too high of a setting on the volume dial. I seriously doubt the knob will ever even get to 2 o'clock since we're talking this set is located in a small living room.... so I'm curious in the academic sense what setting the volume very high on the knob would do even for those high wattage speakers.
As a rule, damage is done only if the amp is driven into clipping. This is a result of having too little power, not too much.
Moreover, a quality AVR like your dad's will have clipping protection designed in, so the chances of harming speakers with it are minimal at best.
I don't think there is an answer to your "academic" question. Suffice to say that if would be above the "0" volume setting, which no mature adult is likely to exceed for long anyway.
As I said in my first response, don't worry about it.
