Baloney!
Nonsense!
They are all horns because they are flared waveguides.
All this baloney arises because few here understand the nomenclature they are using, let along the technology they are attempting to deploy.
Large horns placed in a typical domestic listening space, are at best, an absurdity. Why is it that only most of the female gender, by intuition alone, appreciates this acoustic fact?

Hi,
Its been done with larger drivers, these are waveguides not horns :

Balooney!? hah! Looks like we are getting some engagement here! 😀
That's all good! 🙂
Horn, waveguide, contoured baffle, hornoid or whatever... I think it's safe to at least conclude that those devices commonly refferred to as "wave-guides" are not horns in the true, or at least traditional, sense of the word. to me a true horn is defined by certain formulae giving profile, length and throat/ mouth areas directly related to frequency range to be covered.
The rationale behind employing traditional horn theory is to acheive greatly increased acoustic efficiency and/ or directional controll.
A "wave guide" approach, if I can call it that, is to me more about controlling dispersion pattern, with increased efficiency as a side-effect. This side effect of increased efficiency is in most cases not linear, thus requiring response shaping to get back to a flat frequency response. In it self, this is a drawback, but the reduction in level required to acheive flat response will of course reduce distortion in the same area.
I agree that horns for covering the full 10 octave range is an absurdity, the required dimensions given by horn formula drives that home quite clearly.
The 12" "waveguides" I ordered are not that big, and if they provide improved directional controll down to 1200 Hz, it's bound to be an improvement anyway if this can alter the ration of reflected/ direct sound reaching my listening position.
so, yes, I've ordered the waveguides and it will be great fun to se how this measures and sounds! 🙂
