Just due to beefy notch filter. Otherwise it wouldn't be so pleasant.The break-up and dispersion of the driver look surprisingly good.
By the way at the limit of Xmax you’re expecting 10% THD, so hardly Hi-Fi at 80dB.Well, that was fun
Nothing much unexpected here. With 2.5mm of apparent Xmax you should get about 86 dB at 100 Hz/1m, and even that seems to be distorted, so best guess is that the real Xmax is just around 1mm. The reflex tuning only can do so much to extend the inevitable…
That said, this thing would benefit from something like 6.5” or 8” woofer crossover at somewhere around 500 Hz. Since the driver is only $40, that leaves plenty of budget if you don’t go for the kit option. Then again, a low fs tweeter with a waveguide will probably do better in that case.
The tiny KH80DSP will do only a bit better in the distortion part. I guess it also handles the breakdown it much more gracefully.

See here it’s distortion boundary. It very much tracks with what we see here. There is probably 6 to 10dB more oomph in it compare to the GR. Obviously it’s a far better speaker overall. 10 dB amounts to about double the perceived loudness, so will be quite noticeable.
How to convert xmax to spl?With 2.5mm of apparent Xmax you should get about 86 dB at 100 Hz/1m
Yes, 1mm at 200 Hz gives you 90dB. Coincidentally that is about what it shows in @amirm’s graphs.By the way at the limit of Xmax you’re expecting 10% THD, so hardly Hi-Fi at 80dB.
By the sheer power of math… or if you’re lazy like me, an online calculator.How to convert xmax to spl?
While we're at it: The comparison with the KH80DSP is interesting, because it hasI think the why is clear: selling $300 worth of crossover parts for a $40 driver! All it needs to be believable is to claim it performs better than larger speakers.....
There is no crossover filter.... just a passive EQ circuit.
Nope, parameters are not the same, nor is the magnet material and esthetics.Is this the driver in the kit?
Which and how many "3-way DSP driven monitors"?well stop and think for a minute - it's a 3 inch passive full range driver doing on par or even better in terms of linearity than many 3 way dsp driven monitors...I mean it has to give up on something...in this case the trade off is higher distortion.
Bad sound kills good music.What sort of "giant" is this vastly overpriced thing supposed to kill?
