Hi Folks,
Just picked up some Kali LP8's to supplement my NS-10's. The NS-10's, as typical, lie flat on the console, so I just built the desk so they would be in line with my head.
I'm going to build stands for the Kali's, but I'm not sure how tall to make them. Where should the woofer and tweeter be relative to my ear? I've read different things online, and was looking for an experienced perspective.
Thanks,
Craig

Ask the speaker manufacturer what they recommend, I know they often test with specific setups and it's not the same from manufacturer to manufacturer, and will also depend on if you are using them in portrait or landscape orientation.

The Kali Audio speakers have all kinds of adjustments on the back, so first be sure you figure out which setting you need in the back. I just bought the Kali Audio LP6, but my computer broke so I haven’t been able to listen to them yet, except on the headphone output of my iPad, they seem scooped in the middle and a little heavy on the bass, but that may just be the source.

The EBU standard would be to get the acoustical axis to ear level, 120-125cm. (Use speaker manufacturer data, or guesstimate to slightly closer to the tweeter from the halfway between woofer and tweeter in two-way designs) tech.ebu.ch/docs/tech/tech3276.pdf |

This is where to start, personally I would with some stacked books or something similar to see what worked for me with manufacturers advice as a starting point. |

Good info! I've varied their height a bit to try to find a sweet spot, but wanted something more technically correct. I've email Kali, and downloaded the attached docs.
Thanks,
Craig

I've often wondered how people orient different pairs of monitors. Here's a photo of a studio where the NS10's and large monitors seem to be oriented to the listening position, but the 2nd pair of nearfields (the Adams') seem to be oriented strangely. Perhaps they are oriented for a desk behind the mixer at the console. Would be curious to hear others opinions.  |

Not sure "height" is the biggest thing to worry about. I'd personally worry more about angle, as in are the tweeters pointing towards your ears when you're sitting in the normal listening position..

(Use speaker manufacturer data, or guesstimate to slightly closer to the tweeter from the halfway between woofer and tweeter in two-way designs) tech.ebu.ch/docs/tech/tech3276.pdfI've always wondered about this. 120-125 cm puts you roughly equidistant between the floor and ceiling in a room with 8 foot ceilings, which has a half-way point of 121.92 cm. How far off the floor/ceiling half-way point do you need to go to avoid reinforcing a room mode? I've always made sure that I'm at least a couple of inches off, but is that enough? Edit: I just realized that it's the woofer center that would be responsible for room modes, not the tweeter. So I'm still wondering how far off the woofer center should be from the mid-point. |

I agree with svart make sure the tweeters are angled directly to your ear.
Also a few 6" up or down can make a huge difference in my room, which is moderately treated. As well as maybe a relation to the desk.
So a little experimentation is in order, I suppose.
Make sure your monitor controller is calibrated for perfect L/R response as well, that's a big deal. Use an SPL meter.

The EBU article mentions 120-125 cm, then mentions the acoustical centers being pointed at the ear. Is the acoustical center the tweeter? The middle of the speaker?

If it sounds good, it is good! How about that for a detailed technical answer!

Roughly halfway between woofer and tweeter in two-way designs, slightly closer to the tweeter. The speakers should be angled so that the beams converge behind your head, not in your forehead.

I emailed Kali and they said "The speakers should be place around where your ears would sit while your mixing."
Well, yes, I get that. I wasn't going to point them at my feet!
I think I'm making this too complicated.

Use an SPL meter. I found that I had placed my MM45's exactly halfway (woofer) between floor and ceiling when I was sorting out lowend issues in my room. Dropping them about four inches down made a world of difference. I had read about the problematic midpoint somewhere. True in my case. |

Dropping them about four inches down made a world of difference. I had read about the problematic midpoint somewhere. True in my case. This is certainly why an 8' ceiling is not the most ideal ceiling height: if a speaker stand sits at 36" off the floor, the tweeter or midpoint between tweeter and woofer frequently sits right at 4', which is the 50% boundary. Just as most ideal front-to-back speaker location generally lives around the 38% mark, this is also generally true for the floor-to-ceiling boundary. But in so many spaces (including my own), an 8' ceiling is simply dictated, with no real choice in the matter. And of course, these are generalities with many variables. |

Just to clarify though, my room was purpose built, not your typical 8' ceiling type thing. |

Built some stands out of pvc,.sand, and mdf. Put tweeters at ear height, according to Kali's recommendation.a  IMG_20190612_143141 by |
