Parallel notch filter for Fostex 166NV.

Hello everybody.
Do you know if the Diyaudioandvideo.com parallel notch filter calculator to extract peaks in the frequency response is good ?
In this case is a 7dB peak in 3300hz.

Hi,


The values look a bit strange, but this is difficult to judge without diving deeper into your contraption.
It will, however, be very difficult to "catch" exactly this breakup, which in reality may be different, and to try with some sort of calculator will most probably not work. Also, depending on implementation, a 6" FR driver might need a little bit more of correction than just that 3300Hz peak...
If you want to do it correctly, there´s IMO no way other than


- make your own measurements, in the OB or box or whatever thing you want use.
- get Xsim and learn how to import your measurements.
- learn how to use Xsim. It will get you to about 90% of what´s possible.
- Xsim will also show where to adjust for the final 10%, which should be done by ear and to taste.
- Once done, rebuild your correction with good parts.


Sorry if this might sound a bit disencouraging, but that´s how it is...


All the best

Hola Santiago,


There are many ways to do these measurements, and there are people here much more savvy than me...
I use REW with a Steinberg soundcard and a Dayton mic, together with DATS, and import the files into Xsim.
Most probably there are cheaper ways to obtain these files, but my knowledge of those is very small; others may chime in and explain cheaper possibilities (especially to replace DATS which is around 150$, if I´m right. I found it to be a very good investment...).


All the best

I have used correction network on my AudioNirvana 8" which you can try

Could you point me out the way or the software to use, to achieve the frd and zma files for a driver. I can't solve it alone.
The driver is 18Sound HD1030 , for use with a fullrange Fostex Speaker.
Thanks
Santiago

if you don't have measurement tools, try this

FPGraph Tracer : great software to create FRD or ZMA file from graphic response curve
