Need clarification on my response ...

[salvasol]

I need your help understanding my frequency response ... I'm a little

When we setup REW to test the FR, we use a target of 75db, Right??? ... here is a graph of my final setup.

Using 75db as target ...


Using 80db target


Using 85db target


I know that my FR is higher than the target ... but, How this affect my experience??? ... I like the bass a little higher than the rest of the frequencies (When a set the reference level I always set the sub 5-7db higher )

I've seen some nice graphs (close to the target) ... not like mine

Are this results good or What do you recommend to change???

The target is a reference for REW to establish the filter recommendations. It has no effect on the response.

You aren't setting up the REW levels correctly, so the response level isn't changing between measurements.

Be sure to set 75dB at the listening position and then run the REW SPL calibrate SPL routine, so that the actual SPL is reflected in REW. Then try running the Set Target level routine. It should return at approximately 75dB if all is correct. Then run your measrement.

If you like the sub a little higher, use the receivers internal test tones and set the bass a little higher.

Got it ...

... You aren't setting up the REW levels correctly, so the response level isn't changing between measurements...

The graphs are from a single measurement, the 75db target is the original, and the other two I just manually set the target to see the difference between targets ...

This is the process I did to get the first graph ... Do you think I need to change the EQ setting to get close to 75db target or is this response okay??? ... even if higher than the target

salvasol, we are learning together



Your curve is nicer them mine and my system was set to 75 dB too.

Good to hear that I'm not alone

I think my curve look better because I applied the 1/3 octave smoothing ... ... if not it looks like this
