Note: I have the V1, I've never seen V2 in my life. But they should be the same
Here you go
An article from Kali themself
www.kaliaudio.com
"Some speakers, like the Kali Audio IN-8 are designed to function in any position as a point source. These speakers can be placed on their side. Because high frequencies tend to be more directional and low frequencies tend to be more omni-directional, orienting your tweeters on the outside will widen the stereo image and keep the low end more centered. You can compare this to mixing drums; generally you’ll keep the kick centered while cymbals can have a greater stereo width."
At first, I'm skeptical. But, I have no choice, have to try all the direction myself to verify that, listen for a time, 1 2 days. I find that if I place like they said, it's the best . It just feels right to me . The sound image feels real, connected , continuously from left to right
The normal position, upright, tweeter above, woofer below, I feel bass hit my chest , a bit fatigue
Then upside down , I still feel disconnect compare to horizontal direction
Horizontal direction, but flip them . That's sound so bad, I can't remember anything . I flip them back right away after some minutes , I don't find it worth it to try for any further
My theory is . The higher the woofer from the ground , it helps low frequency from woofer, don't get cancel between the direct sound and the reflected sound of that direct sound from the ground and bounce back . Maybe, 2 woofer of 2 studio monitor get nearer to each other , they get connected ?
I don't know exactly how it's better. Measurement on this forum, even by Erin , erinaudiocorner, only measure single speaker . So I couldn't find any scientific clue to back this up
Again, if you have any chance to do audition yourself, take it , try it
Place them horizontally like that, help me feel superior , professional somehow .... just kidding . Really , only coaxial speaker like IN8 could do that
Edit
Hi there, I should phase it like this for easier understanding
I realize that I should use the word orientation instead of direction
I mean I place them both at horizontal orientation, they lie on their side, woofer inner, tweeter/midrange outer
I don't mean you treat it as single speaker. I have no idea how to set up 5.1 7.1 at this orientation
So I wanna refine my description
When place at other orientation, I feel like the bass is separated away from the whole sound
Hope this make sense
Let's me elaborate more. For example, when place as normal speaker , vertical orientation, coaxial tweeter + midrange on top, woofer at bottom
Use on axis, at tweeter as reference point . Assume everything is the same, triangle positioning, and all the crap
If I get my head higher, I feel less bass. If I get my head lower (nearer to the woofer) , it's sound like bass boost to me . I get confused, some time I find myself love to lower my head for bass boost, sometime I get tired , and wanna get my head higher
Somehow, I feel like sound come from the woofer , separated from tweeter/midrange, I feel something off here
That apply to all other orientation
At horizontal orientation, this effect is disappear . Head down or up, sound just feel the same . Image stay right there consistently , wide, I don't really find myself any urge to move away from the sweet position vertically or horizontally to seek bass boost or less bass, But I do find I'm freely to move my head around to pinpoint instrument position. The sound image is insane
When I get nearer at phantom center . If that false effect still apply, I will feel bass boost because I sit near to both of the woofer . But no, sound is still good. I keep get nearer and nearer until the sound image break away , everything sound off, I can't pinpoint instrument position anymore
Hope my vague description help anyone somehow . Again I'm no pro , this is my anecdotal experience. English is not my native language, so sorry for any inconvenient
