What response should I be aiming for?

What response should I be aiming for?

I have been measuring the response of my 8040s in room using a hand held meter. Using this approach I had to apply 6db bass roll off on the speaker controls and an additional 6 db of attenuation (applied digitally) at 50Hz to avoid a massive peak at that frequency plus gerneral upwards tilt from 200Hz downwards.

However I am dimly aware that some people do not recommend aiming for an entirely flat response. Do you have any particular recomendations in this regard. Should I be aiming (in an ordinary domestic setting) for a curve which gradually tilts up in the bass? If so what roughly should i be aiming for?

Hi,

Unfortunately no official recommendations exists for domestic use. Here is a studio standard we often refer to.



Typically a slightly rising response towards the low end sounds more pleasing if the room doesn't have much absorption (soft materials that absorb sound energy). But it depends so greatly on room and your personal taste that any recommendations are very difficult to give.

Thanks for that.
As a matter of interest does you auto cal software not have a standard house curve in its default settings? I assume there must be some default target response.
If so is it the same as at

Also is that the same as the movie theatre standard x curve?

Naturally AutoCal has a target response which is loosely based on the ITU standard. There is a slight tilt towards the HF, and additionally user can apply extra HF tilt from 5 different options, one of them being slightly modified X curve.
