First Measurement, doesn't look good.

JL F113

13" in Corner with a GIK Tri Bass Trap in the Corner

Cross Over set at 75

So I have a null in the room at 35 to 45 and then again at 63 to 75.

Thanks for your input.

I merged your threads. It's hard to follow if you keep opening a new thread each time you post.

Am I reading this correctly?

You have your graph set to Linear scale. Change to Logarithmic scale. Press the Freq Axis button in the top right hand corner of the REW application.

Set your vertical scale from 45dB to 105dB. The horizontal scale is fine.

Show the crossover target that you're using (i.e. 80Hz) so we can see how the sub tracks the target.

Normally we worry more about the peaks than the dips....

Does this graph look like what you are talking about?

[Jerm357]

Yes, but go down to 15hz.

And add the target curve.

Got a chance to move the sub around a little.

What graph do you like the best?

Hey Michael,

How drastic were your moves? I'm a little surprised at it staying so similar. You've really got that dip at 40Hz!

Hey Otto,

I didn't put up this graph. The first graph was in the corner 20" off the GIK Bass Trap. The second was moved over next to the speaker.

This is one on the side of the room.

Hi Michael,

It might be easier to tell the differences if you plot them all on one set of axes. Just do all the measurements (don't delete them; you can only store nine at a time I think). Anyway, once you get a variety of measurements, you can plot them all together by selecting the "All Measured" tab here:



Once you're in there, there will be checkboxes that will allow you to turn on/off the display for each measured (they will be organized by the date/time they were measured).

Hi Group,

I put my sub in my seating position, and found the area that 40 registered the highest. I ran the graph and compared the two.

What do you think?

I like the front corner better for music, but the back corner for movies.
