| So the tweeter is always needed. The bad thing is it deforms (in 99,9999999999999999999% of the cases) the perfectly round audio window, formed by the midrange channel and "pull" some notes sometimes at its axis. These are often the notes that have their fundamentals at the upper working range of the midrange channel. The higher the midrange channel extends (but only if it has good tonal complexity in its upper range!!), the less prominent that effect is. Doing this, it deforms the coordinate system of the sound field and mainly affects its deepness and unlimited openness. It could be very easily detected by just listening only one of the channels of a given stereo system. But first of all, I have to note this cannot happen if the midrange/widerange channel is not able to project that coordinate system. Everything depends on it. In the world of direct radiators it is mainly a matter of size of the driver. 8” widerange could not even dream for open space presentation, despite the fact it can have mind boggling tone. …. Not even 10” – it could present the correct size of the images, but there is still a lack of the original space around these images. 12” – this is another world, but only if made properly. There are no 12” widerange drivers made commercially that can do this, so unfortunately no one can understand what I’m talking about. About the world of horns – I do not know – I just don’t have enough experience, but I suppose there is a minimum diameter of the horn’s throat (just like there is minimum size of the voice coil of direct radiators) in order to be able to project that space. |
