I like the language of this brochure !
Regarding the x-over: I would say it is also 1st order on the woofer branch.

Interesting. Could make decent surrounds.

Holger Barske has tested the MAX 2 although the version with a LTH 142 waveguide:

One 18Sound engineer went to work for Ciare (now owned by 18Sound) and designed a similar looking horn.

The same guy is also responsible for the Faital Pro horns.

German manufacturer Seeburg Acoustic Line developed another interesting elliptical horn.

Nowadays, they mostly use the known Italian horns.

I have seen the Ciare one on the US speaker website. It costs twice as much as the XT1464 and is only about 8" by 12" in size and made from cast aluminium.
It apparently has the same entry angle as the exit angle of one of the 1.4" RADIANs.

There is one big difference between this one and the XT1464: While the XT1464 is curved in the vertical and horizontal axis (I don't know what the mathematical function is on These) - this Ciare horn opens conically in the horizontal axis while the vertical axis is such that the area grows at a hyperbolic rate. It has therefore constant directivity in the horizontal axis and narrowing directivity towards higher frequencies in the vertical axis. A bit like the classic radial horns. There is even an academic paper around that deals with its development.

I was once interested in this one for a smaller MTM with 12" or 10" Woofers.

Regards

Charles

The rectangular one could also be the XR1496 with an oval diffraction slot. I guess the XT1464 is better soundwise that that one.
I wonder why they finally went for the LTH142 on the Max 2. Maybe just because it looks better than th XT1464. Who knows ?
