low frequency

[arivel]

Hello everybody .
I have a technical question for you.
there are many types of horns and waveguides, but which is the best technology for the diffusion of low frequency audio waves?.

 

[markbakk]

What do you mean by diffusion? in general, frequencies with wavelengths about two to five times bigger than the radiating 'surface' (cone, horn mouth or source in a baffle) will spread omnidirectional around the source.

I apologize for having formulated the question incorrectly and try again.
if i had to choose a waveguide or a horn suitable for low frequencies which type should i choose? perhaps a hyperbolic one?

 

[markbakk]

The exact horn typology and it's pro's and cons is frequency independent. The only thing relevant is that you need bigger horns for lower frequencies. For domestic use, check the Klipschhorn which uses room boundaries to extend the bass horn.

That being said, for low frequency reproduction there are a lot of in-between solutions that aren't really horns. You'll find those mainly in PA audio applications.

What do you want this device to do for your bass?

Have a look at a 40Hz horn, you can not call that a waveguide any more.
