When Danny looks at speakers he measures the frequency response, spectral decay and impedance.  When I look at the measurements of the NX reference series and X series it seems that some of the X series speakers has a better spectral decay.  If you look at the Bravo and the beast and even the x-static they look very clean.  The NX-treme and NX-otica special decay doesn't seem to be as good as these but the NX-studio has a really good spectral decay.  Am I looking at these correctly? I know this is just one small piece of the puzzle

How exactly are you doing these measurements?

How exactly are you doing these measurements?

I was looking on the GR Research website.  Maybe I'm looking at it wrong.

[Mallard1]

I have noticed the same thing and had the same question.  When i look at the spectral decay of the Xstaik versus the extreme it appears the X series is cleaner.

I think the difference is the tweeter.  The GR NEO 3 has some longer stored energy but it's still pretty clean.

I agree with above. There's some stored energy, but it's a good 20db down where most of that issue issue and would be tough to hear. I'd also just expect a magnetic planar with a long ribbon where energy could transfer end to end to have more stored energy than a well dampened soft dome too.

I've seen tests where a very cheap soft dome outperforms nearly every ribbon in most measurements, although people tend to like the extra shimmer of a ribbon which is actually that measured distortion  http://www.zaphaudio.com/nondomes/

It's mostly minor edge diffraction/reflections caused by the original waveguide, and in some cases probably the tweeter itself at higher frequencies.

I'm working on updating the crossover design for the X-Omni, and I'm seeing similar little trails that are seen in the NX series kits.
You can also see them in the original spectral decay below:

There is a slight difference in them due to the edge diffraction of the waveguide. I just shot a video on reading edge diffraction that will be up shortly. It is a very educational, tech talk style video. I hope you guys like it.

I'm looking forward to the video. I'm comparing X-Static and NX-Studio kits and wondering about the differences (other than size). I can imagine some of the differences such as MTM vs. TM, for example.
Thanks!

The NX-Studio is more detailed with a more airy/spacious treble.
The X-Statik has deeper bass with a very open mid-range that is a great combination for vocals and string instruments.

The NX-Otica & NX-Tremes are the best of both worlds offering a very open/spacious sound from 50Hz-20KHz since all of the drivers are in an open-baffle design, rather than just one or two drivers.

Perfect. Thanks!
