Horn question?
Hi
I have a question on horns and compression drivers. If I wanted to use a horn from say 200 to 10,000 hz, what is the limiting factor - the compression driver or the horn. Let's assume that I had a perfect compression driver, is there a horn design that would work properly over such a wide range? Dan |

The horn.
This horn from the mid 1920s has a 1" exit compression driver and a ~40-14 kHz BW that was nominally flat from around 80-5 kHz IIRC: home 200-10 kHz then is trivial, especially if an ideal driver were made for it. The problem with such a wide BW horn though is one of extremely narrow 'sweet spot' and why a large multi-cell coupled to a huge, truncated FLH was invented: http://www.voiceofthetheatre.com/ima...catt1945.9.jpg GM
