Hi all

Yes, the thing with midbass/upperbass horns , as Romy states, is that those horns are usually built to be too short. You might actually be better off using the driver in a sealed box.
For example, look at the size of a typical upper midrange horn, and compare it to the frequency area that it is used in. The horn of such a horn is usually quite generous compared to the length of the wavelengths it is meant to cover.
Let's say, just as an example, that you want to make a horn to cover from say 1000Hz and up a bit, using a compression driver. Now, you'd probably make a 500Hz horn, with a length of at least 50cm. The wavelenght at
1000Hz is about 35cm. So the horn have a length longer than the longest
wavelength it is asked to reproduce ( 1000Hz ).
Now, on the other hand, compare that with the horns pictured in Romys post. The wavelenght at 100Hz is almost 3,5 meters......
