House Curve Or Filter Change?

**NismoZ** · **02-10-08, 12:06 PM**

If you had a flat response line, what would sound better trying to achieve more low end bass?
1) Loosening up the filters around 20-30hz
2) Inputting a house curve?

Well, the result is basically the same. A house curve is simply modifying the target line that REW will use to recommend filters. It will give a more accurate result by offering something to shoot for, rather than a random dialing of filters.

I think how you accomplish it depends on your baseline response. Mine, for instance, is naturally tilted towards the low end, so it made sense for me to equalize towards a house curve target (manually that is, not using the REW recommendations). Other people’s graphs I’ve seen didn’t have a natural low end exaggeration like mine, so it made more sense for them to flatten response, then “overlay” a broad filter or two to accomplish the house curve.

Don't know what to recommend for you without seeing a graph.

Here it is...

Ok, that last graph was without a house curve...

Here is one with 320hz, 120/60 and -15 dialed in...

Here is one with 320, 120/60 and -15 with filters 1 and 2 lossened up...

On all accounts, it looks like the house curve filter destroys the filter I have set up @ 90hz...

I am going a bit crazy with trying to get this into shape. My line looks pretty flat without a house curve, but I'm not sure that my curves look good when in place...

I need some help here guys.

Not really, it looks about right for the 320 Hz filter you set.

Try doing some listening evaluations to see which one you like better, or maybe a variation of one of them.

Say you created a flat bass line. What would the difference be from 20hz to 80hz in a curve? A difference of 5-7db lower @ 80?

In Part One of the house curve article you’ll find instructions on how to determine the curve your rooms needs.
