Default Question on bookshelf speaker placement

I have two bookshelf speakers that sit towards the back of my desk,
flanking two monitors. The tweeters are a few inches below ear level.
Would it be better to tilt the speakers slightly backwards, or just
raise them up? Also, I sit close enough to the desk that I'm slightly
closer to the speakers than they are separated from each other. Is it
better to move the speakers slightly inwards (such that they are closer
to the monitors) or backwards (where the monitors might start to block
them)?

Alan,

the speakers slightly backwards, or just raise them up?

Raise them up, don't tilt them.

I'm slightly closer to the speakers than they are separated


Here's an article you may find useful - it describes how to set up a room
with the correct listening position and speaker placement:

Probably, but see below...

They may be positioned horizontally best where they are but...

You are dealing with a "Near field" type arrangement which
depends on things a little different than a full room type setup.
In a near field arrangment (like a full room setup), you want to
avoid blocking the direct signal. The speakers CAN be set too far
apart if you are really trying to tweek'em.

The great advantage to your setup is thaa it is easy to
experiment with :-) Get two friends to come over and just hold
them in a couple of positions while you listen. You will be able
to tell very quickly what the "best" position is for you.

If I read this right, following the 38% rule, in a 20 foot room,
one could sit either 7.6 ft from the front wall, or 7.6 ft from the back wall,
to achieve a good compromise of peak vs null. In the latter case, would
the theoretical ideal be to place the front speakers 7.6 from the front wall?

Steven,

speakers 7.6 from the front wall?

That's a great question and I don't have a good answer for you. One other
influencing factor is the distance between the speakers and the side walls.
Maybe you could aim to put each speaker 38% of the way in from each wall,
but that may put the speakers too close together or too far apart - it
depends on how wide the room is. The reason I showed varying "axis lines"
for the speakers is to adjust them along those lines for the flattest
*measured* response. I use the ETF software (www.acoustisoft.com) which lets
you run such tests easily.
