Compression drivers Part II (News)

Hi Johannes,

Here is the link to the german forum go to
"Hörner" an look for Weichenupdate für BMS4590/JABO KH50. The horn he uses
is an different Type, but the shape is a Tracktrixcurve as well.

Thanks for the link but that does not cure the real problem...

Basically the driver is not designed well enough, there is a huge gap between the high and the midrange simply because the midrange driver is not going high enough, there is no overlap between the two drivers. Even without any filter there is already a 6dB dip at 5kHz, connecting the standard filter reduces the output of the high frequencies (on their lower end) making it more balanced in the higher frequencies but adds ripples in the midrange.

Also, the whole midrange remains too strong (> 3dB) and needs to be EQ-ed.

With a digital crossover and EQ-ing the higher midrange makes it very easy to create a balanced sound but that is not someting I want to do...

Now that I have found the problems does give me a rough idea what to do next though...

Bert
