Help for a newbie with REW...

[Wayne A. Pflughaupt]

Yeah, between 9 and 12 Hz is not much numerically speaking, but on the frequency spectrum it's fully half an octave. Shifting things up higher will get you a better perspective - imagine the difference between a 90 Hz and 120 Hz crossover.

Since you're using an outboard amp I imagine this is a DIY sub? We have a forum for those, too, you might want to check it out.

What I had meant is without running a HPF, my Mal-X would hit its Xmax limits at 12hz. With running a HPF at 13.50hz, it is right below its Xmax limits at 9hz, so if the HPF is set at 12hz, then raised up a little bit, I could be right at that or above.
But, what I was getting at was, if the EP2500 didn't put out 2000w (or 1950-1900w) at 12hz (which would be where the sub would hit its Xmax limits would be without a HPF) I could possibly set the HPF lower, or not even need a HPF at all.

Would there be a way that I could test the Receiver's low end roll-off just by connecting a voltage meter (or something; I don't know what to use) to the Pre-Out channel?

Thanks again for the help, and sorry for the confusion.

Edit: Oops. I didn't see the second page before I pushed the post button.
Going from 90hz-120hz Xover is quite a bit
And I got my box dimmensions and everything that I needed (and some) for building a DIY sub. They were a great help over there and I appreciate it. I would probably have bought a Klipsch $400 sub if I hadn't come here, and now I have one that is much much better
