That is true. But you are misunderstanding the speaker specs. Max Input Rating is not how much power you need to power the speaker with. There's no such thing as "an 80 watt speaker" or a "200 watt speaker." Again, it's the sensitivity you should be looking at here. A higher sensitivity means it will put out more sound (volume) with LESS power. Kind of like miles per gallon. The way you're thinking about it is backwards (like thinking that you better get a lower MPG vehicle because you know that you have very little gasoline available).

I assume the same with the Center 1 which has a Max Input rating of 80watts as well. With that being said, I am under the assumption that since the specs for the larger Center 3 require more watts, that this would be a bad pairing (?). Maybe my real question is, will the Pioneer damage the Center 3?
The Center 3 does not "require more watts." The manufacturer is saying that you CAN throw more watts at that speaker before bad things might happen. This has nothing to do with recommended pairing of amplifiers. If you worried about such, their other spec, Suitable Amplifier Power, is something you can look at. For the Center 1, they say 15-120 watts. For the Center 3, 15-175 watts. But this is more a generalization of the class of amplifier, not necessarily how many watts you'll put into the speaker.
So, if you were telling us, "My application for this amp & speaker is that I need to output peak 100 decibels from this speaker sitting 12 feet away," then we'd note that:
a) With any speaker sensitivity of 89 decibels, your amp won't cut it, because you'd need 170 watts for that one channel to get to that loudness.
b) The Center 1 is not rated by the manufacturer to handle that much power. Either by their 80 watts or 120 watts spec.
c) The Center 3 is also too weak a speaker for this application. Although it'll do better, as they say the max input power is 120 watts.
How loud do you expect to go? It might be hard for you to know this if you haven't heard clean, compression-free systems that are playing loud. Those will sound deceptively not-loud. It's when one over-drives weaker systems and there are distortion components in the sound that make you cringe, that you think it's "too loud." And you can't equate what you're hearing into decibels unless you have a sound level meter.

I've included the thread's link below for reference. If any HT gurus can help, I would greatly appreciate the words of wisdom. If this receiver turns out to be a bad choice, then I plan to return it for something that will be a better pair for the Mini Monitors and future additions (Center channel & Surrounds OR Front Towers, Center, and turn my Mini Monitors into Surrounds).
It depends on how loud you intend to go, with what speaker. Again, with a LESS powerful amp, one would want a MORE sensitive speaker. If you're worried your Pioneer is tricksey-spec'd at 80 watts per channel, but in reality with the front three channels firing in unison at max output over difficult-to-drive frequencies, it only can do 30 watts per channel, and you'll be asking of the amp 70 watts per channel....then you should get a MORE sensitive speaker. The Center 3 is more sensitive than the Center 1. And when you are sending bad distortion to the speaker, the larger Center 3 will be able to take it better than the smaller Center 1.
Some good stuff here. You can learn how manufacturers play with the specs to make the product look better. Like my spec-ing my car, "Max Speed: 130 mph (downhill 10% grade)."
So, this quote: post#61:
What's most important is that your speakers are efficient. If not (6 or 4 ohm, 89dB or lower), get a better AVR.
So he's labelling as not efficient (or not suitable for this receiver) 6 or 4 ohm speakers (they're not inefficient, just difficult to drive with an 8 ohm rated amp with a weak output), or 89 db or lower sensitivity speakers (which is what the Center 1 is). Because to achieve the same loudness, you'll have to turn up the amp MORE with the Center 1 (eg 70 watts). With the Center 3, you won't have to turn it up as much to achieve the same loudness (eg 56 watts), thus you're not stressing that weak amp as much.
So, in summary, if you have a weak amp and you're worried about it being asked to do more than it can handle, get a more sensitive speaker, or don't turn it up too loud.
If you have an insensitive speaker, then get a bigger amp.
If your insensitive speaker can't handle much power, then you also can't turn it up that much. So you weak amp will be fine.
Without an SPL meter it's hard for you too judge what's too loud, so that might be $50 well spent at your local Radio Shack.
