Great Waveguide List

Really looking to get down a little lowerthan 750hz if I can.

The SEOS 24 (diysoundgroup) unit has a 7degree throat angle , but my driver is 0 degrees. I assume I can't 3D print an adapter as the geometry is not like old type horns that have a constant geometry. - they seam to change from a straight line at about 45 degrees for most of the horn into a tight radius just before the throat entrance.

This would mean I am left with a 7 degree sudden angle change....not what I'm looking to pay that kind of money for.

Are there any alternatives? Or would I have to 'roll my own?'
 
The 2452 is a throat-less design. I highly doubt it would make any difference worth mentioning. The wave at the exit is never perfect anyways. Might be spherical at some frequencies and planar at others before any influence of the horn takes shape.
 
How could there not be a throat?

Hello Noah

Here is a cross section with a JBL throatless driver using a coherent wave phase plug

XT1086 is one of my favorites but the QSC measures a little bit better.

XT1086 is handy if you need narrower vertical beamwidth.

The nail in the coffin is that:

1) The XT1086 is aluminum, which makes it hard to work with for a Unity horn, if that's your goal

2) You can buy five of the QSCs for the cost of the 18Sound

3) Unfortunately both are discontinued
 
There are chinese clones from xt1086 made sort of composite material. I had pair but i sold them cause i had no use for them and buyer wanted to try if theres some difference to sound "plastic" vs metal horn.
