Anyway this was my last EQed response run on REW. With room treatments.. Though I don't remember if I had my LR mains set to large with subs or small with subs when I did this measurement.

rhed the graph looks good but at the very least you should have it in 10dB increments but preferably 5dB not 20dB and I would suggest using 1/12th smoothing too.

+1

5db increments and 1/12 smoothing is pretty standard and gives a better indication of what is going on.

Here is a 0-300 sweep with 20db increments and 1/6th smoothing - almost perfectly flat



Same graph with 5 db increments and 1/12 smoothing



Same with 5db increments and no smoothing.

Yep, I love the look too!! I'm just under 6'1" so yeah, pretty much same exact height as me too. They look a lot better without the grills too.

Sounds like a good plan Dave, I know you have had your eye on the Emotiva.

Thanks.. Yea.. I dug this out here in my gallery. I'm gonna change it when I get back from my vacation. See how it looks with 5 db increments. I know I save every measurement done with REW on my LT. I'm not gonna do anymore REW measurements again till I add the two OS Pro's I have planned for early 2015. I've read reviews about the OS Pro's over and over how beastly these would bring out the midbass more. This should be a interesting addition. Though I will have to sacrifice one of my dedicated line for it. It's probably the one for my avr.

This is good information to know because when I first used my Omnimic, I ran a FR with 1/6 smoothing and it looked pretty good as you posted above. I thought, wow, my room is pretty good I don't have must tweaking to do. Then I ran it again with no smoothing and it looked like snaggle toothed witch...just like you posted above and I thought...dagnabit...my room sucks and I have lots of work to do to get it smoother I've never run 1/12 smoothing but I'd imagine it will be between 1/6 and none but the question is....


Wouldn't no smoothing be the best in terms of "truly" seeing what's going on in your room instead of 1/12?

Probably.

I think 1/12th is how we would hear it.
