Filters and stuff   4 comments

I’m working on a advanced training for those who are interested in it. So i’ve seen remarks by people on the internet/forums suggesting to others to try certain filters instead of the ones they use on there speakers and have “problems/issues” with. Also people seem to think it might be a good idea to use other filters/speaker settings recommended by manufacturers. Changing settings without knowing the consequences can and probably will cause a worse outcome if you can’t verify everything you do without some kind of measurement device capable of transfer measurements (so not RTA;-) and knowledge regarding loudspeaker tuning…….

Here’s a start on filters out of in this case a APEX intelli-x2 processor which has most of the more common x-over filters used nowadays….. If i have time the next few days/weeks i’ll try to get measurements on a few more exotic filters (elliptic out of the Meyer Sound galileo ; Elliptic out of a XTA ; NTM out of the BSS blu80’s and the phase linear filters out of a linea processor currently available to me)

The channels visible in the screen capture are 1 mic (that’s the audio track audible mic vs reference (pink noise) both mono tracks).

The data i took how ever consisted of Mic 1 onax/Mic2 ofax-6db horizontal/Mic3 ofax-6db vertical/Mic4 middle between onax-ofax/processor low out/processor high out/average of mics 1-2-4.

You can download the data below.


Enjoy 😉

(You might compare filters out of your processor with the ones in the zip file. Specially the Bessel filters might surprise you when compared between units).

  1. I’ll attend your training, will it be online?

  2. Sorry it’s not a online training. You have to show up at my place in the Netherlands……
