KEF Q950 Best Speaker placement for Stereo imaging

[Rajkumars]

Hi all

I have KEF Q950 in a rectangular room size of 12 x 23 feet.

What is the best layout of speaker placement, how far apart should the speakers be placed from each other .... Distance of the speakers from the front wall, side wall and the listening position ....

I am currently not happy with the imaging .... Any help or advise from the wise people will be very helpful ....

Feel free regarding the placement .... I would do anything to get the right imaging for Stereo music listening ....

Hi Rajkumar ,

Would be good to know the way it's currently setup & what issues you are facing with imaging that you are not happy with & your reference point for imaging which is making you feel it's currently not adequately setup.

Some general pointers basis of my observation besides the final fine tuning which helps
i) Center imaging is best achieved via symmetry on both front and side walls in terms of distances , space around & reflection points ( generally there is some.compromise needed around these but should not be a major concern)

ii) Make sure speakers are in a straight line as much as possible and have a similar toe in angle to your listening position. This impacts the imaging very much , once this is ensured you can experiment but changing toe.in angles.

iii) Distance between the speakers also helps , if they are too close to each other they can sound off.

Lastly a common basic check is to.make sure the connections are not out of phase , this makes the overall playback very incoherent & is easily identifiable.

The best way to get wide realistic soundstage is to get a DSP with channel crosstalk cancellation.
Right speaker sound going to left ears and left speaker sound going to right ears is the ultimate stereo imaging killer.

It will be better if you can describe what part of imaging you didn't like

- Bringing speakers together closer will improve richness in mids and vocals. But can impact separation. Vice versa is true as well.
- Distance from side and back wall. Depending on the room treatment you have, having 2 to 3ft distance from side and back walls always gave better results for me.
- Avoiding clutter between speakers. Try to keep them clean as much as possible. Move your equipments behind the speakers.
- Acoustics treatment - First reflection points, behind the speaker, ceiling, carpet and behind listener position. These make huge huge difference. Reflections mess with a sound stage a lot. Having a uniform RT60 decay across the spectrum, gives a big benefit.
- Start with equilateral triangle in listening position. And then you can move back as you prefer. This is to figure out the nulls / bumps in low end. Every room will have it and they are hard to get fixed in room treatment. That happens generally in 50hz to 120hz. Avoiding that automatically give a uniform response.
