Are KH80 or 8010 really better especially in vertical dispersion? For sure they don't play as low and are at least twice the price. I think I'll get them just for fun and as a second reference on my desktop, if they don't hiss too much
You may want to hold off until the Topping 4" speakers are out. Measurements presented seem to indicate excellent dispersion, even if some on-axis ripple will need EQ.
There are some measurements on the website although not the complete spinorama data.

Linearity on axis is great. From the horizontal and vertical we can see that dispersion is ok but not excellent imo.
PS: that abrupt 24 kHz fall hints of an internal 48 kHz sample rate.
That's actually in the specs.
The measurements answer one question I had, there doesn't seem to be an automatic shelving of bass but you can dial some in using the Position control.
Distortion is a bit of a head-scratcher.
The ~1.3 - 4 kHz "valley" seems odd and rather out of proportion with max level handling, although the response generally follows that:
While the woofer may have a naturally rising response, I wonder whether the waveguide-like recession might be at work there as well. That being said, e.g. the KH80 woofer behaves in a similar manner (though it can play a lot louder, that's a 4" for ya). In any case we're seeing relatively strong cancellation between excursion H3 and electrical H3, so it's clearly not exactly a Purifi level driver (but I mean what do you expect at the price, probably the usual Al voice coil former kind of job). I wonder how it would do in IMD testing.
The tweeter is not exactly a super great performer, but since it only ever has to
tweet >4 kHz, that shouldn't matter too much. (Looking at similar drivers like
this that want to be crossed over at 5-6 kHz, it seems you really need a waveguide for them to even play as low as they are.) 30 W for that seems a bit overdressed.
And remember what I said about excursion limiting at the low end? That's a perfect example right there.
PR tuning seems to be relatively deep, with a boost around 50-60 Hz, reflecting the desktop use case.
I guess they may not have wanted to make the response too narrow, so they left in some tweeter widening (plus, nearfield). Vertical dispersion is a bit weird, with best results somewhere between +7 and -12°. Maybe they were optimizing for a reference plane slightly below the tweeter?
