hi could Bruce? wayne? john? or any one else of the pro's answer this...
like this "edia2368's graph in this post for instance.....

whould it be better lo let REW auto adjust the peaks/filter(s) the first 1-2 runs?
like this for example :

first run:
1.adjust sub to 75db (or 85 or 105) ref level
2.use the "auto" set target level in REW
3.Find filter peaks
4.set filters
5.Optimize+adj. gains
6.send filter(s) to bfd

second run:
1.adjust sub back to 75db (or 85 or 105) ref level (since its lower after first run)
2.use the "auto" set target level
3.Find filter peaks again (this time REW probably finds more peaks)
5.set filters
6.Optimize+adj. gains
7.Put in the filter(s) in eq setting from previous run to this run manually
8.send all filter(s) to bfd
9.adjust sub back to ref level again

then make minor adjustements if needed....?
whould this be wrong way to go?
thanks/Hasse
To expand a bit on brucek's advice, the purpose of a second run would be to see how well the EQ filters worked out in “real life” as compared to how REW predicted, not to see if or where “new” filters should be applied. If things didn’t quite turn out right with the first set of filters, you don’t want to “pile” new filters on top of the old ones. It’s better to go back and re-adjust the first filters to get the desired results. Make sense?

Wayne
