yes they can, but they not all are a mess in HFs, it depends of the size of the throat, the good respect of fins position, if there is a pinch at the throat (diffraction horn)...
In one word it depends of the conception, it's a complex horn, I have tested several of them, all were different in HFs due to specifics choices that have a huge impact on it.
Some are (IMHO) unlistenable in HFs, others yes and even very good.

How to Make a New Wave Biradial Horn
I've been working on this little thing for a while now. Fairly similar, but different corner geometry.

Is that 3D printed? And an AMT/ribbon in there?

Yep, each horn took about 17 hours to print in PLA with a 25% grid infill and 3 0.45mm perimeters to make it plenty sturdy. The transducer is a ribbon from a Fountek NeoCD3.5H. I replaced the stock CD horn with the printed one for a little experiment, works surprisingly well. It's currently used very high up (~15k first-order) and fills in the upper treble where the Fostex driver wanes in response, so the next order of business will be a full 2.9kHz two-way third-order Bessel crossover to see how the horn behaves with the current loading.
