I agree vertical is also messy but again to be expected with this type of design. I see what you are seeing but I don't see that as any major errors below 15khz out to 50-60 degrees. It still follows a similar contour with what I call minor changes in contour. When looking at the contour graph I don't just look at the red section which looks "narrow". I look at how the contour changes as its db decreases. On the the contour the orange section which is down 3-6db and the yellown section down 6-9db is to be expected after about 500hz-1khz. and greater. I look for any big changes in the contour or start getting major dips in the off axis graph. I see some minor changes in the contour but nothing that makes me say, "wow that is really poor".
Compare that to the Rokit or the Ascend acoustics from that same website and those start having problems at much lesser angles. I think we are being a little academic on what we call wide dispersion or how I was taught and assess speakers. I would say the Kali are very good at ~ +/- 50-60 degrees which is where they are about 10db down and contour differences become greater. This is still very good compared to many speakers but something like the Elac I would rank excellent at >75 degrees. I wouldn't call the Kali narrow dispersion. There are a a couple factors when I look at something off axis. One does it follow a similar contour and two how much does it decrease in db. For instance something like the discontinued Genelec 8260 had one of the best horizontal off axis I have seen, even better than the current "ones". It not only followed a close contour but was down less than 5db at 60 degrees, truly outstanding! Most are closer or greater than 10db at 60 degrees and that is still considered very good as long as the contour or response graph still show a similar shape.
Nice website by the way, I will have to save that one. Thanks for posting that.
I do recommend Kali LP 6 V2's regularly and think they are great speakers especially for the price. DBR62's where one of the last presents from truly great designer (Andrew Jones) who whose there from golden age boom in 70's and I hope they will go into history as truly great and affordable.
Regarding site I still have some faith in scientific institutions.
Best regards and have a nice time.
Well, seems like you guys have gone waaaaay past what I'm capable of understanding haha. Haven't had the time to read your conversation in detail, but from what I did understand: The difference is sound quality is marginal between the 2 seems to be mariginal only does the Elac had a (slightly?) beter dispersion, which is beneficial in my situation. Also, I like having more flexibility when it comes to connectivity. So I think I'm going for the DBR62. They may not sound as good als the Kali's with my old Kenwood amplifier. But improving my setup as times pases by is a part of the fun for me.
