So I just got the Kali IN-8's V2.
With the volume knob on the back at middle position they have less hiss than my Behringer Truth B2031A's not zero but barely hearable for my old ears, which I must say are not optimal anymore, especially in the highs. With the knob on full they have similar hiss compared to my Behringers, so I chose to push a bit more volume into them instead of max the speaker amps. They go loud enough for me at 1.5 meters distance.
What is very notable about the amps on the back is that they don't get warm. It might be they don't produce heat, or it might be that they vent through the bass port. But the metal backside stays room temperature the whole day. The behringers get very warm and noisier during the day. The Kali's don't.
The soundstage is wider and the depth is deeper to my ears. I hear a lot more detail and variance in depth on these speakers. I A/B switched between the Kalis and the Behringers, in comparison the Behringers sound upfront with no depth at all.
As for the bass. For now I give it +20db at 38hz, but I will tune it with a sinus by ear as soon as possible. I will also check it with room eq wizard asap. I don't know yet, but there is something up with the bass response right now, there is a lot of variance between tracks, Maybe I need a few filters to get it right. Lift the upper bass a bit more as well maybe. The amount of bass with a 20db boost is enough to not need a sub. On the other hand I will experiment with the Behringers as subs as well if I can get equalizer apo to filter my secondary outputs differently. I don't know if that is possible.
By the way if you boost the bass 20db you have to lower your input signal a bit, so you have enough green on the output else you'll run into digital distortion / clipping.
As for the on / off axis thing. I have them at a tiny angle from my backwall, but I think they could go straight inline with my backwall as well.
It seems to lift the highs a tiny bit, when I had them full on axis I boosted 9000hz with 1.5db, now at this angle it seems okay to me without eq.
Above 10khz I roll it off completely, because I hear very little above 10khz and don't want to damage my ears further with stuff I can't hear.
Looking at Erin's frequency response it goes up 5db above 10khz.
Nothing to note about the body of the speakers, no scratches, Both sides look the same, no extra glue, no rattling.
So to me the Kali IN-8 V2 deliver. Let's hope they last.
