I went with the C version because of the better dispersion of the tweeter. My room isn't huge, but it is bigger than some. I am glad I did, because I think this Selenium tweeter is excellent.

but I do know that this arrangement does not have the dreaded horn "shout" or any other colorations that to my ears identify it as a horn. IME this is the result of using the wrong kind of amplifier on the horn, rather than something inherent in the horn itself. Most older horn designs have crossovers that are not designed to work with amplifiers with lots of negative feedback (low output impedance); this results in crossover errors when such amplifiers are used. The result is that the horn may be playing information out of its proper passband! *That* is where that honky shouty horn reputation comes from. for more info see: http://www.atma-sphere.com/Resources/Paradigms_in_Amplifier_Design.php |
It may be the case that some of the characteristic horn coloration and "shout" has to do with crossover/amp compatibility, but, clearly, some of it has to do with characteristics of horn reproduction itself. I have heard big changes in sound from use of different damping material on the exterior and interior of the horn itself. Also, the same driver used on different types of horns can deliver completely different sound. I also suspect that, to some extent, it is the midrange peak of typical horns that, to some extent, creates the impression of great dynamics and liveliness. Those horn systems where such peaks are tamed and tonal balance is actually quite decent also tend to sound a bit less lively. |
