It's a statement against the youngsters' addiction to screens, yes.
I am not exactly young... but still feeling like a 16 year old sometimes

One shouldn't kill one's inner child.

Possibly, but Marcel did some sims of a horn made of flat slices, to see if the work to blend them was really necessary.
The results looked "sub-optimal", to be polite.
But maybe not much effect in this case.

That will be informative, thanks once more.
I suppose if the horn is built from flat slices then the slices are cut essentially the same so the only extra work is just a bit of calculation.
It just seemed more work to think about.

Best wishes
David

LeCleach has been mentioned too. Not my personal preference to terminate a waveguide, in theory it could be quite different to a radius.

Good thing as they were pretty rare even before the bulk of them were scrapped.

Awesome.....thanks!

So what do they call that mouth configuration?

Technically it's a truncated front loaded horn [FLH], i.e. a 'slice'/section out of a full size 'x' Hz horn.

This cabinet is designed for the 604E?
I'm using mine now in 9 cu. ft. Stonehenge cabinets.

What was once old is yet new again. Altec had a mid range horn like this in its 9862 studio monitors: Altec Lansing 9862 - Great Plains Audio

No, for the original 605, which would have been driven with a matching impedance amp with variable DF tone controls: 1945 DUPLEX

Your 'E' will need similar EQ to 'fill up' the 110.

Thank you.
I suppose if I was to undertake a project like that I might as well just go for the A5 system.

1) At the point of inflection the radius of curvature of both curves should match.
2) You can implement this profile, and others as well, with a single fairness curve. [1]
3) Check out the profiles generated by shape optimization regimens. [2]
4) The declining curvature in the throat, gently spreads a higher pressure wave front.
The increasing curvature at the month mitigates lower pressure wave reflectance.
