A bunch of fun stuff I learned about Audio and Video for 1080P content

[Jeremy Duncan]

A Near Field Speakers are just beyong your arms reach.
A Mid Field Speakers is 7 feet away.

Mid Field is supposed to represent the sound better than Near field.

A example of a Near Field Speakers is the Z5500.

A example of a mid field speakers is a music studio room. They’re big speakers.

So. I see a lot of so called “Show room” home theaters. ANd I see these tiny speakers and a couch 10 feet away from a tiny front projector screen and it has too much light.

And I wonder.
Do they know WHAT a Near-fild or Mid-field speakers system is, and that they have “Sweetspots” that need to be calibrated using a spl meter?

So I’ll post a thread asking this very question.

And since mid speakers work on 7 feet. Your monitor should be just big enough so your not more than 7 feet away from your center speaker under the monitor.

I read here about people 12 feet away. I dunno.

“near-field loudspeaker system. We suggest placing the front speakers on a desk per the diagram shown here – just out of arm’s reach from a seated position”

“Speakers, mid-field: speakers designed for control room and studio applications that are several feet away from sound reproduction equipment and that provide a more accurate reflection of subjective sound than near field speakers can.”

What I’m saying is that since you should sit no further than 7 feet from your center speaker if it’s a mid-field speaker.

Than your 1080p monitor, the actual screen portion.
Should be no higher, measure from top to bottom, should be no higher than 28″.

So if you have one bigger than this, you’ve messed up somewhere. Either with audio or video.

Here’s how I got the 28″ number.

7 feet = 7×12
Divide this number by 3 = 28
So this becomes 28″ height on a 1080P screen.

Viewing 1080P content on a 1080P monitor that is 28″ high, from 7 feet.
Considering your front center speaker is flush (and is a mid-field speaker), with the screen.
Would be the correct htpc home theater setting for both audio and video.

To get that 28″ height, your looking at a 54″ tv.
This would be viewed 7 feet away, the same distance away from the front center speakers. Assuming the speakers are mid field speakers.

people who have 100″ screens must be sitting about 7 feet too far from mid-field speakers. So their audio must be all messed up.

The largest the tv should be is 64″ at maximum and sitting 7 feet away, with the front mid field center speaker flush with the monitor.

To get that 64″.
Distance from tv in inches / 2.4 = maximum Height of tv, not diagonal height.
This is assuming your viewing 1080P content on a 1080P monitor.

Edit. This is assuming your using a 16:9 screen, viewing 1080P content on a 1080p screen.
