Distance from speakers
« on: November 18, 2007, 05:43:32 AM »

Apologies if this has been covered before but I did a search and couldn't find what I was looking for.

So how far do you sit from your speakers and why??

Is their a optimum position?? or does it depend on the room and speakers??

Whats the best way of finding the best position?

Any advice would be great.

I used this guide and it works well.

 http://www.cardas.com/content.php?area=insights&content_ id=26&pagestring=Room+Setup

or you can use this guide

http://www.realtraps.com/art_room-setup.htm

Or you can do it by listening and adjusting until it works correctly for you.

Best of luck, it is a fun thing to do and you get to learn a lot about acoustics.  Smile

In my Post room I go by the Guidelines of the P&E Wing at NARAS.

Recommendations for Surround Sound Production

The distance to each speaker should be between 6.5 - 7.5'

For my Mastering room, we had to choose the best listening position by ear and analysis. Yes it varies between each room and speaker type. I'm about 8' from mine all the way around.

Experimentation to determine what translates best from your room to the outside world is likely the optimal position.

People always tend to critisize reflections from desks. But they never mention what the desk possibly absorbs.

Or walls. Or floors. Or roofs. Or keyboards. Or monitors.

Or your body!

Think about those two for a while and you'll need no-one to tell you where your speakers must stand to fit YOUR EARS. In your room. The reflections contra the absorbtions.

You only need to point your arm into the direction of a speaker to realize that there is no such thing as optimum anything.

There are a lot of spelling mistakes in that summary. You would think that something that is posted on the web would be checked for spelling errors. I hope his calculations were better than his spelling. Confused

thanks for all the info has been most insightful.

for the record I don't have a desk as I don't have much hardware like some of you analog guys. I have this nice wheely thing that I bought from IKEA for about

i never had any problems with the equilateral triangle rule; the listener should be as far back from the speakers as they are apart from each other. currently, i'm near field, with my HR824's three feet apart and myself three feet away. it's like being in a cocoon... mmm... cocoon.

The Dunlavy manual says that the best distance for their far-fields is 9-12' in front  of the listening position.  Their manual also suggests putting the speakers in opposite sides of one of the long walls, with appropriate toe-in for the image to point at the listener, who should sit along the opposite long wall.  Also, the listener should sit with his ears at tweeter height when listening to an M-T-M array.  I have departed somewhat from the recommended starting position described above, since my long walls are not appropriate for having as front and back, because the short walls are not symmetrical in their rather permanent acoustic treatment.  One is a large, vintage shag carpet-covered bass trap/dead end, the other is a flagstone rock wall/live end with parquet floor.  It used to be a late 70's tracking room.   I have therefore placed the speakers about 9 feet apart from each other along the  large bass trap wall and sit about 12.5' in front of them, in front of the rock wall with a somewhat narrower (4' H x 8' W x 4' D - filled with Roxul

He won't listen.

I think it depends on the drivers too.

If you bump into Dave Collins hereabouts.

(He may be very interested to learn how to position speakers)


Please send him here. Basically, it’s all written just for him.....

Hi "Peter,"

I did read it and also looked at the BMW links.  There was also something in there about a Petula somebody.

Oh, the RH that I referenced wasn't Ross, but engineer Ryan Hewitt.  He has a 335i, the B*stard.

Nice car.

that guys method leaves you sitting almost directly at the center of the room. Not a good idea!

and his web site goes on to say

"An infinitely indivisible progression known as the Fibonacci sequence or golden section is the key to resonance control. The ratio of Phi, or 1 to 1.6180339887...to infinity, is the Golden Mean, called golden ratio or golden proportion. Cardas Audio holds the patent, U.S. Patent Number 4,628,151, where the ratio of Phi is applied to any electrical conductor.

In Golden Section Stranding, strands are arranged so that every strand is coupled to another, whose note is irrational with its own dissipating conductor resonance. This creates a silenced conductor, allowing Cardas cable to produce the purest possible audio signal. No other cable geometry, no other conductor design, can create the listening magic of Golden Section Stranding."

Those patented Phi/Fibuonacci sequence cables are golden alright! Golden Goose Eggs!

“Mispelling is often the sign of a good tech”

Dear Tom,
You must be a brilliant technician.
The word ‘mispelling’ does not even occur in the dictionary.
I believe the word you meant to write is ‘misspelling'.

But misspelt it.




Sorry just catching up on this thread. No that spelling was intentional P. it's called a joke ... Glad to see that you picked up on the subtlety.

My purpose in writing is not to correct you, but to publicly convey your convincing technical prowess and engineering experience to the whole world.

I'm concerned...

Has there been too much fungicide sprayed on the apples you’ve been eating recently?

As appears to be the case demonstrated here...

Also a joke?

I personally don't agree with everything Mr. Cardas says BUT his system for setting up speakers seems to work for my situation(with a little "by ear" tweaking). I think his cables are overpriced and some of his ideas about cables are a bit "off the wall" from a physic's standpoint but he seems to sells a lot of them to golden eared audiophiles.....

I noticed that you were quick to shoot down this method but did not offer any suggestions that you had used and worked well for you so could you enlighten me what system you use in your "mastering room" and why you have found it to work so well.

By the way if you do the math you will see that you are NOT in the middle of the room if you follow the advice quoted in my original post.
