We've seen these kinds of dome tweeter arrays before, like the JBL CBT series, but not with an explicit reference level claim. The datasheet offers extensive measurements, which look essentially flawless and would seem to confirm that claim.

Since I have found no further information on the brand or speaker other than the FB post I got the datasheet link from, I'll just leave this here. I assume if they're selling anything, they'll come out with it eventually.
 
Here's the accompanying sub:

This one is much less outlandish, a passive 15" 4 ohm sub in a closed box with a 92 dB / W / m sensitivity.

Crossover / sub placement could get somewhat awkward, given that the ZS1011T better be crossed around 200 Hz for best level handling. I'd be curious what kind of arrangement they had in mind for their "up to 16" subs each.

One (or more,some do that) of them right next to the speaker, or as a base.

What is it made of and it only weights 23 Kg???
I mean, ok, it's small at 68 cm height, but still...
 
The rest of the website is empty?
 
We discovered this thread a little late - but better late than never.

Thank you for discussing and being excited about our speakers!

We have made no formal announcement about us or our products so far. @amirm as of this moment has one of our ZS1011T for the purpose of a public review, and we also have a another sample out for review locally (Central Europe). When the first reviews air, we should be introduced to the broader public.


Some preliminary information:

  • Sounding describes the practice of deliberately shaping the transfer function of a playback system to create a certain sound signature. With us, there is none, or Zero of that - hence our name.
  • at the moment we focus only on reference, no compromise level speaker systems.
  • all customer speakers will be made on order, sales are exclusively directly via us.


In addition to the ZS1011T's datasheet, which has already been linked to, we are glad to answer your questions; again, late, but better late than never:

Hello Steph. For the vast majority of use cases, ~100 Hz will be perfectly fine as crossover frequency. But you are correct, for maxing out the ZS1011T in the mid-high frequency region, the best cross-over region to the subwoofers would be around 200 Hz. For that purpose, the low frequency support elements, such as our ZS15S (though we are currently transitioning to 12" subwoofers for even greater flexibility), will have to be placed as a monostack or tightly spaced for full coupling up to the crossover frequency. Due to our likely exclusivity for our pricing alone, we will be personally available to every of our customers for a perfect setup of their Zero Sounding system.

I designed the waveguides for this speaker and assisted in the overall acoustic design and processing needed to realise the needs and desires of the developers. Waveguides and arrays are two areas that I have particular interest in, so being given the task to combine them together was something easy to say yes to :)

Tightly controlled dispersion in both planes for use at high PA SPL levels but also very low levels of all types of distortion across the entire frequency range was the aim. It may not be immediately obvious but this speaker has reducing non linear distortion as frequency rises. This is actually uncommon, because many speakers have increasing levels of non linear distortion as frequency rises (particularly those with extreme SPL capability) from issues of excursion limits, air non linearities or wave steepening effects.

The form follows function in this design to allow the levels of objective performance shown in the datasheet. If anyone has any technical questions on the design, I may be able to assist in answering them.
