Speaker Placement Questions

post #1 of 12
Thread Starter 
Using Infinity 150's for sides and Infinity OWS-1's for the rears

1. Do I keep the side and rear surrounds the same height or is it ok for the rears to be a little higher?

2. I've read the sides should be slightly above the ear and also 2 feet above the ear. Which is preferable?

3. Do I angle the side and rear surrounds down so they are pointing right at the main seating position?

1. All speakers should be the same height.

2. I've read that too, but it's old advice based on obsolete information.

3. All speakers should be pointed at the main / center listening position.

It's useless to talk about placing the speaker until you determine the location of the midrange driver within the speaker enclosure.

The MIdrange Driver needs to be slightly above the listening ear level (if the speaker sits level).

Have someone measure the distance from the center of your ears to the floor when in your normal listening position.

Then try to position the speakers so that the center of the midrange driver is at that height or slightly higher.

If a speaker is angled up or down, of course, then the midrange driver should be "aimed" at the ear location.

With floorstanding speakers, using adjustable feet or spikes front and rear and adjusting the speaker "tilt" will aim the midrange speaker further up or down as needed.

Awesome thanks guys. My rears will have to be a little higher than the sides because of things on the back wall. Would it then be prudent to angle the rears down to point them at my ears at that point?

Found out the Infinity 150's have no mid only low and high range drivers. Will they still sound good as side surrounds or should I look in to something with a mid?

Also, the sides will be about 33" from the listeners ear. Is this too close? Can Audyssey make up for this if it is? Thanks.

Yes, though angling speakers is always a compromise.

I plan to use floor standing speakers for my fronts, and surround left and rights too, but I have seen graphs that show different ways of putting the surround left and surround right speakers. In the Dolby site it shows for a 5.1 which I can only have, that the surround L/R speakers should be placed each left and right side of you're seating position. But then there are others that say the Surround L/R should be behind you and they should be split apart at an angle like Ethan's graph shows.

What's the right way to place them?

Side and rear surrounds don't have to be super-duper to give good results if properly positioned. Infinty 150s can work well in systems with very high quality L, R, center and subwoofer(s).

It's worth a try!

There are lots of right way to position sides and rear speakers.

You want to avoid sonic holes between the speakers.

The information in my Room Setup article above is based on standards established by the NARAS wing of the Grammys, also linked above. This is how the people who actually create surround mixes set up their monitoring. So if you do the same, you'll come closest to hearing what they heard. (Assuming you also have proper acoustics and treatment in your room.)

Ahh I see. Well then it only seems proper to set it up that way, thanks for the info.

Varying the angle of the surround, is that an issue?I have a room where its impossible to line up surrounds without having them be at the back corner of the room making it approximately 150 degrees from viewer.The best i can do is left 90 @ degrees and right @ 115 degrees. Is this angle a concern for accurate surround sound? I've read through the forums that distance isn't an issue due to calibration adjusting for it, but how about angle of the speaker location to viewer? Speakers are Pioneer BS22 .Thanks
