Where should my target curve fall?

[Talley]

So I finally got around to running REW to see where I'm at with my dual sub DIRAC setup. My target curve I plugged in was +4db @ 20, +2.5db @ 50 and +1db @ 80hz. I did not boost anything below 20hz so basically anything sub 20 is at 0db.

This is where I'm at. But not sure where a normal "target curve" or "home curve" or whatever you call it should be for movies.

We like to see unsmoothed graphs for subs, but that curve should sound just fine with movies. However, I find that a curve like that sounds bloated for music; as such I prefer a hard-knee curve for music. You can do a search on “hard knee house curve” and find an article I wrote on the topic over at HTS.

My bad... here is unsmoothed:

There is no special curve unique to movies. What is right for movies is right for music. The fact that people like to boost the crap out of their bass is unrelated to what is right.

As you saw in my other response to your related comment the Harman work suggested 10dbs boost at 20hz relative to 20khz. Essentially a ramp shaped slope.

I am not sure how Dirac works on the Emotiva piece. With the software I find you will clip the signal if you try to apply 10dbs of boost. What I do is apply no or little boost and just make the rest of the curve quieter.

If your system rolls off the highs a lot at 20khz uncorrected just go with 15khz as a reference instead.

Of course you want to listen and decide for yourself. I actually do have multiple curves depending on the music and my mood. I don’t always like the bass setup this way. I believe the curve I’ve been using is actually 6dbs hot at 20hz relative to 15khz.

Well this is the average over all three front channels.

20hz is actually 8db hot over 15khz.

You mean 20 Hz?

Yes sorry.

I want to give my current curve a bit of a try... isn’t like to just compare stereo mode vs dual mono on my subs
