Romy, the actual sound benefit of this 4-channel upper bass configuration, is rather in the type of sound presentation. The commonly used single upper bass horn (or direct radiator) sitting under the midrange horn, gives the feeling that the midrange floats over a dense and soft upper bass cloud. It is in a way interesting effect, but it is much more interesting (at least in my view) when the upper bass radiating area is very big AND equally distributed around the midrange/main channel. This creates an effect of having huge and very widerange coaxial driver, which gives the unique feeling that the upper bass is real physical part of the midrange, loading the whole (!) room with tone. Actually it can no longer be detected as upper bass sound – it just becomes part of the instruments. And this is much more important than the fine tuning of the sound of all these 4 horns. |
