I am afraid that you either did not read post #4 or did not understand it; I probably was not clear enough.
I tried to answer your questions in that post. I apologize if I was not clear enough for you to understand. I will try again, and be more direct and clear where possible.Yes, you are completely misguided and wrong regarding the "1200 watts". NOT correct.
First of all, you would need 1200 watts of amplifier power to hook up to them before you could find out if they could handle it. Speakers don't make power; an amplifier must supply it to them.
The 1200 watt number is an attempt to imply that those speakers can put out 1200 watts of audio power IF you hooked amplifiers that big to them
(which is extremely unlikely), but that is WAY more than they actually CAN put out; that is total bull-crap! If you ever had amplifiers big enough to apply 1200 watts to them, they would certainly go up in smoke in less than one second when you did it!As a matter of fact, 1200 watts of actual audio power in most rooms would quite possibly damage your ears (and it would take 200-500 pounds of HUGE speakers to produce it, NOT some dinky little speakers like you have).
It's like if you went to buy a little economy car and it had a sign on it saying "Never drive this car over 200 miles per hour!". Pure nonsense!
The only power rating that is meaningful to you is the rated RMS output power of the audio amplifiers of the receiver.The Yamaha RX-667 has 90 watts maximum undistorted power per channel, with 2 channels fully driven. This is all you care about as far as power is concerned. This is probably all the power you will need for most HT listening with almost any speakers.
The 630 watt number is simply 90 watts per channel multiplied by 7 channels, but in reality your receiver is not capable of supplying 90 watts to all 7 channels at once, so that is only a nonsense number. It has nothing to do with reality.
The RX-667 can put out 90 watts to one or two channels at the same time, but there is no way it can supply all 7 at once with that much power, because the main power supply that runs the amplifiers is only able to put out 400 watts or so (not 630).
Do you care? Maybe. Maybe not. Most people will never have any problem with that
because they will never turn it up loud enough to exceed the 400 watts actually available from the receiver power supply. All seven channels do not normally operate at or near maximum power all at once.
In normal listening you are probably only supplying 1 to 10 watts of power to each speaker. Really cranking it up to high volumes can make that go way up in a hurry though.
Some people MAY find their receiver runs out of power at very high volumes if they really crank it up high, and the sound gets very distorted .
In that case they are trying to push more power to the speakers than the receiver can give; the power supply is saying "NO...I can't do it!"
If this is a problem, the way to fix it is by adding another 2 (or 3) channel power amplifier
to your system. What you do then to hook it up
is hook the PRE OUT jacks of the receiver's front 2 (or 3) channels to the inputs of the new amplifier channels and hook the front speakers to the new amplifiers. Now the new amplifiers power the front speakers and the receiver only has to power the other 5 (or 4) speakers.
That makes it MUCH less likely that the receiver will run out of power at high volume.
The subwoofer normally has its own built-in amplifier to run it, so in that case it needs no power from the receiver; just a connection.I am fairly sure that I answered every question this time, but please ask more questions if anything is still unclear.

I appreciate the information you have given me thus far, but unfortunately, my main questions are still unanswered. What I meant in my original post was this: on the Panasonic "home theater in a box" link I shared (the current system I OWN right now
), it said the total output power was 1200W. Unless I am completely misguided, this determines the loudness and overall power of total system when cranked to full volume, correct?
But now, when I am shopping around for receivers, they seem to have total output powers that are much much lower than my current system (i.e. the Yamaha receiver I shared had a total of 630W output power). So does this mean that if I use that receiver for my setup, 630W is the maximum output?
Or is there something else involved that I am not aware of?
My current knowledge is simply this: You buy a receiver, speakers, and a sub woofer, and connect them. Is there something else you add to the system to increase the power? Do you use an amplifier? How does that amplifier connect to your system / what does it do?
