In which case you would definately need more amp, particularly if you listened with the door closed. \:o

Not merely my "take" Micah; simple principles of physics. Listening distance is the key.



Ok so simple principles of physics would go like this... Listening distance + desired decible output = AVR/external amp.

In other words for JohnK,

10 foot (listening distance) + 86 db's (desired decible output) = AVR (sufficient for the job).


for Micah,

16 foot (listening distance) + 120 db's (desired decible output) = external amp (necessary to achieve goal).



This is correct, yes? Personal preference for volume certainly comes into play in this equation. How loud you wish to play movies/music on your speakers is the biggest part of the equation when figuring out if you'll need external amplification. Room size and listening distance are also important, but it's the decible level you are trying to achieve that ultimately decides this debate.

The simple physics discribed demand more power to achieve higher db levels. If my Denon can achieve 120 db's in my room at my listening distance, then that number is in error in my example, and it should be higher. Because what ever the db level is that the Emotiva drives my M80's to, it's higher than the Denon is capable of. So what ever that number happens to be, replace 120 db's with it, and this will be my equation.

It really is simple physics after all. \:D

Correct, Micah; about 4,000 watts needed.

Super sweet, looks like I get to add a few more amps to my rig! ;\)

... I also need to find where the best place is for the sub up front before I build it.


The best place for the sub will require you to have the sub in the room and move it in different locations. The easiest way is doing the sub crawl found HERE

Also, are you looking to hide the sub up front? Because up front may not be the best place for your room response...

I read that article. I am going to try and find an up front location for the sub, hopefully front and center, vs right or left corner. Then I'm going to build the cabinets around all the speakers. I know it's not ideal from a pure audiophile perspective, but it's a necessary compromise. I'm going for as clean a look as possible.

Form follows function in a perfect world. However, what we live in is far from a perfect world. If there were no women on this planet, Home Theaters would look very different indeed as most men, free from the binds of compromise, would seek ompimum performance first, and then worry about the way it looks second (if ever).

On second thought, perhaps it's a good thing we have women around! ;\)

"ompimum", never touched the stuff.


Half of communication is listening. You can't listen with your mouth.

"ompimum" is what you get when you try to be too efficient and eat while you type. ;\)
