Hello everyone! I've been having fun trying to learn REW. Let me know what you think of this graph, especially if something looks wrong.:sweat: This is Sub only measurement. Front left corner of my room. Thanks for looking.

It's apparent that you read the REW Help files - most don't.

You sub looks good, except for a typical room peak around 38Hz that may be reduced by positioning, or EQ if that doesn't work...

I would add the mains and do exactly the same measurement you did with the sub only plot and see how they mix at the crossover and see if anything new pops up.

Thanks for the quick reply brucek!
I went back and ran another measurement, full range this time. Seems like I have a bad null around 57Hz...is this something that will make a noticeable difference if fixed? If so how what would be the best way to go about it? This room is in the basement and 3 of four walls are concrete block! Eventually they will be sheetrocked, but at the moment movies at high levels seem piercing. Hopefully sheetrock and acoustic treatments will help. Any advice is welcome.

Not at all. The sharp dip is too narrow to be noticed.

Your biggest concern is the peak at 38Hz.

Either way, I would wait until the room is complete before doing anything about your response.

Hello,
there is nothing you can do to make the nulls disappear, just move them if you change the location of the sub. Seeing them is bad, it makes things look very bad, but it's the peaks that can be disturbing.
