Same here. Just had an offer to test the LP-6 so hopefully we get to do that soon.Very much look forward to Kali Lp6 review if it happens.

I wrote the qt/python app that was in the diyaudio thread on this subject (parked in https://github.com/3ll3d00d/pypolarmap). It produces such views from imported IR data with selectable colour maps (someone made the point in the other thread about how perceptually uneven jet is) and normalisation on a selected reference axis. If you want something interactive them probably easy to resurrect that though not hard to write some simple script to do this either. In what format does it export data?It lets you change their colors or if you want them displayed. Nothing much past that. I need to export the data and plot it elsewhere for something different. If anyone knows of a graphics app or website that creates 3-D graphs from these, let me know. Short of that, I may have to write something in matlab.
Reviewers get sent the equipment. If you have a big audience, you may get to keep it. Then you don't get sent anything if you have give negative reviews or if you talk about objective things. It's almost all a huge scam, plain and simple. 99% chance of getting fd.
Thanks. It supports ASCII, VACS and binary Matlab from what I have seen (these are measurement graph exports).I wrote the qt/python app that was in the diyaudio thread on this subject (parked in https://github.com/3ll3d00d/pypolarmap).

Does this include SIBR effects which is dependent on distance from front wall? Some speaker designs include wall support and need to be very close to the wall.
It is a computed curve which shows a theoretical average of SBIR effects.
Does the software allow normalization for contour plots? Would make the directivity more readable..
For these monitors, yes. They are typically used this way. For stand-alone speakers I will use a different setup.@amirm, are you doing the listening tests with them on a desk top? Shouldn't there be two listening tests, near-field and far-field?
The DI curve for early reflections is broken. Klippel has confirmed and testing a fix. It is not yet working in the main graph but is as a separate graph:First, the DI curves super smooth, and most of the bumps and dips are present on the big three curves(LW, Early reflections, sound power).
First, the DI curves super smooth, and most of the bumps and dips are present on the big three curves(LW, Early reflections, sound power). That means EQ-ing this speaker to an almost ideal response should be pretty trivial, since none of its problems appear to be major directivity issues.
Normally we don't want to EQ above the schroeder frequency, but since we have anechoic data (again, thanks amir!), just bring down the bumps that are consistent at every angle, or bring up that low-mid/upper bass dip.

... I mean this speaker is very cheap for an active 3-way with 8" woofer...
Klippel NFS can generate the compensation curve that once applied to in-room measurements, produces anechoic results. It is relative to measured in-room results however. So not the same as what REW does.This was what I was getting at in another thread, measuring the speakers is a great service to consumers but I was curious if the Klippel software is able to provide PEQ filters to match a target (ie flat) similar to REW. If not can the data be exported into REW so we can mess around with the EQ function ourselves? All that would really be required are the Spinorama curves, not every measurement. You can eyeball the graph, of course, but it would be a bit more precise with some kind of software giving us the PEQ values.
Since the IN-8 does have such well behaved directivity indices, simply EQ'ing the listening window to be neutral should make the whole speaker very good.
Some potential considerations so maybe @Sancus doesn't have to give it away to someone he hates:

As you see, it is not smooth at all.

No need to eyeball the graphs or make Amir do any more work =].
Vituixcad, a free speaker design app, has a very handy "SPL Trace" function. Open Vituixcad, go to Tools, select SPL trace. Import a screengrab of the klippel measurements. Set your graph boundaries and SPL levels, then tap on the curve you want to copy, which in most cases would be the listening window for PEQ purposes. It looks like this:
Might take a bit of adjustment to get it just right, but it's usually pretty easy. Then just tap export, and you have a response you can import into your app of choice and create filters for.
Thanks a lot, that is awesome and would be really useful. I also agree the ERDI isn't that bad but it would take quite a bit of EQ to fix all of it's issues, that's a speaker I would pass on personally. Many speakers have a few resonances that could be fixed and made to be much better, a good example is the LS50 that I currently use, here's a "Spin" I found in a study that doesn't name the speaker but calls it a "2-way Coaxial with an MSRP of $1499", so I'm pretty sure it's the LS50.

You can see that fixing the listening window with a few filters at 750Hz and 2k would make this a much smoother speaker, which I have done and can confirm. This is a good example of a speaker with a few problems that can be made even better with just a few filters
Stunning. How many have they sold? Starting when? And this bug is found by a crazy hobbyist's website?!??The DI curve for early reflections is broken. Klippel has confirmed and testing a fix.
