Tower placement

Recommended Posts

Ive always went for the triangle method (fronts are 9 feet apart and 10.3 feet away from MLP) but I found this interesting on Klipsch.com.

 

I wonder if I shouldnt bring my fronts in a bit more...

 

Where is the best place to put my main speakers in my room?

Correct speaker placement leads to the best sounding bass and the best imaging. It is generally a good idea to keep speakers 4-6' away from side walls to minimize early reflections. Those reflections upset the tonal balance of the speaker and also interfere with proper imaging. In general, placing a speaker closer to a corner or back wall will produce more bass. Raising a speaker off of the floor (such as putting it on a stand) will reduce bass. The two (or three) speakers you have on your front channels should also have their midrange/tweeters all at the same height in order to create an even image. It is particularly disconcerting when a pan jumps up and down as it moves across the front stage. 

Finally, we recommend, with Klipsch speakers, that the midrange/tweeter horn be "toed-in" toward the listener to create the best imaging. Experiment with distance from the back wall till bass balance is smooth and extended. To achieve good imaging without a "hole in the middle" do not place speakers father apart than the distance between you and the speakers. That is, not more than an equilateral triangle. If your speakers are too close together, you will reduce the width of the image almost to mono. Try to keep the distance between your Left and Right speakers a little more than half of the distance from you to the nearest speaker.

I have the toed in part covered.

 

 

"To achieve good imaging without a "hole in the middle" do not place speakers father apart than the distance between you and the speakers."

 

I have that covered, I mean 10.3 feet to MLP and 9 feet apart.

 

This is curious:

 

"Try to keep the distance between your Left and Right speakers a little more than half of the distance from you to the nearest speaker."

 

That would almost make me feel I needed to reduce my distance between the fronts from say 9 feet to 7 feet, and keep them toed in...

That is a recommendation of the MINIMUM distance between the mains. You need to read it in context with the previous sentence. "If your speakers are too close together, you will reduce the width of the image almost to mono. Try to keep the distance between your Left and Right speakers a little more than half of the distance from you to the nearest speaker."

I found mine sound best when the distance from the sidewall to the center of the horn is half the distance between the horn centers.

ie. if you have 12 feet between the center of the left horn to the center of the right horn then the distance from the left horn to the left side wall should be 6 feet, same with the right side.

For 2-channel music, as close to an equilateral triangle as possible, IMO.

 

For HT, as close to the sides of your screen as possible other wise the imaging will be way too wide.  I used to have my RF-63's deep into the front corners toed in to my LP and when panning occurred on the screen, the sound appeared to come from off the screen either to the right or the left.  Moved them in about 2 feet closer to the TV and it made a huge difference.  

 

With this change, I thought stereo music would suffer a bit but was pleasantly surprised that it didn't.

Where is the best place to put my main speakers in my room?

 

I highlighted "best" because I think the answer depends on several things, including how big is the room, how big are your speakers, and personal preference.

 

The room is sometimes 50% of how your speakers will sound.  I like large speakers a little further away from me if I have a choice..

 

The third point is the one I would emphasize.  Some people listen loud and like to have the speakers pointed directly at their ears, sometimes placing laser pointers on their speakers to get precise aim.  I have heard of others using this method to point at opposite ears, so the right speaker points to the left ear, etc.  Some people find the "aim to the ears" the most intense, but fatiguing when listening for long periods.

 

I would suggest "best" means personal preference, place them where they sound best for you and your ears.

Interesting Bill, I had never looked at it 2 channel vs HT, and Im just about 100% HT.

 

I currently have them toed in aiming at a center spot about 24" behind the MLP (spot in between my wife and I), so it is not a very aggressive toe in, but they are toed in. Front right shoots across my left arm rest (I am on right side) and the front left shoots across my wifes right arm rest. I have the RC64II staged at an up angle so that it is basically aiming at our faces.

 

I did use a laser pointer for all the stuff, just making targets with blue tape. For the center, I stuck blue tape on my chair where my ears would be, and adjusted the 64ii up until the laser was equally above and below that tape, when shot from the top and bottom of the 64ii cabinet. Not sure how better to do it, and I guess that could be OCD overkill.

 

I am just wondering if I should bring the 7ii's in anymore, which would allow me to pull the subs in too, or if they are fine. During 2 channel they sound fantastic, but it sometimes seems on HDTV and Blu-ray that I get more sound from the closest tower, or it's obvious, and I wonder if that means I have them too wide.

 

I guess that also could be a product of the MLP being a small table between my wife and I, because checked at the MLP all speakers are right on 75db with the reference test tone.

LOL!  Ya think:lol:

 

Seriously, your efforts surpass any suggestions most of here have to offer, and you are certainly more sophisticated in your setup than anything within my elementary skill set.

 

You shouldn't be asking for advice, you should be dispensing it.  B)

LOL. I tend to over think stuff, and sometimes I get bored and feel the need to mess with stuff. Not broke, don't fix applies.

 

I basically just set my 7II's up the same way as the 82II's without doing any research on the needs of the larger compression driver, if there is any difference at all.

well there is your problem right there. MLP needs to be your seat! I try to always get my seat in the middle where your table is but not always pleasing to the eyes. If you calibrate in your chair then it will set your mains accordingly. Everything will sound like it should then. I have a friend who always calinrates off to thensidenehere he sits. It drives me crazy since I have OCD but I've heard his room so many different ways and when he calls where he sits the stuff really does image perfect even though he is off center.

Pointing the tweeter directly at the ears is not my cup of tea.  It can be fatiguing.  I like to aim the mains slightly behind the MLP.  Personal preference is the key.  The more one  puts into proper setup, the better autocalibration works!

Thats pretty much how mine is. I sit on the right, right front is toed in and aimed at a spot 2 feet behind MLP mark. That basically means it is aiming at my left shoulder, give or take a few.

The problem with toeing out with home theater is that if the distance is already pretty wide due to straddling the screen, the opposite tower is kind of weak in the opposite seating position and the speaker on your side plus the center is much louder than this opposite tower. For two channel music I wouldn't get any further apart than is necessary and toe'ing out would work best in this situation.

I'm in the same toed out a bit camp. My mains are aimed about 2' behind my listening position. I think it all depends on the speakers themselves. On axis brightens them, because the higher the frequency, the more directional it is, and the quicker it loses amplitude. If you want them brighter, aim them more at you.... Too bright, aim them behind you more... The bass amplitude will not change much with axis changes.
