Re: Another First Grapher Needs Help


It's been several days since my last post and a lot of trial and error. I tried everything a 75db with my input and output set at 1.0 and kept getting a message that my input was low so I upped to 80db. I am using sound blaster live external. Anyway here is my uncorrected graph.

So a set the following filters

HZ ______ DB ____ BW

35.76 ______ -13 ____ 11
27.28 ______ 5 ____ 9
20.25 ______ 6 ____ 6
80.25 ______ -5 ____ 24
327.8 ______ -12 ____ 120 For the 8db house Curve

And I get response like this.

My question here is am I being to aggressive at raising my low end at 27.28 and 20.25? This is a Revel B15 sub and should be giving good output down there but is that kind of boosting uncool?

Then I added my mains and get a hump at 50hz. So I add another filter to bring the sub level doown in that area.
48.5______ -3______ 9

It helps but now looks like this after adding +4.5db to my sub in the AV speaker levels and the mains added to the graph.

Should I get more aggresive with that 50 hz area to compensate for the mains? What is that dip at 72 all about? What else should I be concerned with?


Thanks

Tom
