Looking at those, and being a newbie, IIUC, your left and right mains are interfering at different points with the sub. They are not symmetrical? If that's the case then one delay would not be able to fix the issue.
The speakers are pretty symmetrical relative to the TV/CC. However the MLP is to the right of the CC/TV by 2-3 feet.

Or one of the mains is out of phase?

yet the CC+sub is off by the same amount as L+R+sub

I think the symmetry relative to the MLP is the only thing that matters. The point of the equilateral triangle is the MLP so the position relative to the TV doesn't matter with regard to the sound.

OTOH, I bet it looks good.

Couple of questions regarding measurements and graphs:

1. On all SPL graph should I put horizontal line at SPL level I measured? If yes, where do I read out SPL level of measurements?
2. Are decay/waterfall readings in direct corelation with peaks/nulls of frequency response graph? For example, lets say i have a nasty peak at 200 Hz, then I assume there will also be long reverberation/decay times at that frequency? But, is it possible to have a dip, for example at 1500 Hz, but at the same time have really long decay time at that frequency?
3. How can I figure on ETC graph which frequencies cause peaks that need to be tamed? I figured I can only read distances to reflection points, but that doesn't help much if I don't know which frequencies cause peaks. Someone mentioned that ETC is only useful for high frequencies, does it mean that it doesn't show low frequencies?

Good morning,

Anyone want to take a quick look. do i need to eq anything?

The response below 100Hz looks pretty flat, with a nice upward slope. The response above 100Hz looks typical. The dips are narrow, and probably can be controlled with room correction. How about showing a full-range measurement to 20KHz with smoothing applied, either 1/6 or variable?

Side comment: the black background makes the graph harder to read, at least on my tablet.

ok nice, ill take those measurements right now:). i will also change the background to white. i added the image as an attachment instead so see if you it looks better. brb

Yes, I can read the legend now.

Attached is full-range measurement to 20KHz with var smoothing and the other with 1/6 smoothing.

Well, I have an unusual setup involving the bed as MLP and small bedroom (due to a back injury that just won't go away). However, if you see where I started in Jan 2015 (in terms of HT setup/calibration and placement/quality of speakers) when I got into this hobby, you'd be very impressed. I know I am.

I find it amazing that your sub goes all the way to 20KHz. Can you hear that?

Indeed it is. Now we're just trying to get that last little bit more. Are the delays on your mains the same? Maybe you can address the dip by adjusting those delays.

Or, possibly, since this is HT, ignore the mains and just address the dip on the Center's graph. That might also improve the L/R.

Only one word of caution from me - and it's not break-in. Always allow electronics/speakers/etc to fully acclimatize to the ambient temperature within your home before powering up...
This makes perfect sense to me, thank your for the input. I think I'm lucky in that the sub is coming from about 1.5 hours away so the temp should not be wildly different from when it's delivered, but I'll resist the urge and let it sit for a couple of hours while I set up the mic and laptop. Never know how hot or cold the storage facility/delivery vehicle might be.

Perhaps you can also just replace the amp (if that's what died):

I plan to try to repair it if for no other reason than to learn something. I have the diaphragm and speaker out, just have to get in to the box and take a better look.

Thanks very much for the link, between that and what the guys on the Klipsch sub gave me, I'm hoping I can use it in my office surround system if I can resurrect it.

Not bad at all, MrGrey. I suspect it sounds pretty good. I don't see any obvious issues in the frequency response curves.

Next step would be to post both a waterfall (which would allow us to view bass resonance), and the ETC (which shows how well reflections are controlled). Instructions on how to generate both are in the guide. Please follow the posting guidelines.

its sound incredible. this is the first time i can say i am really enjoying my system. it just sound right:). thanks allot for the help. i will read the guidelines and be doing those graphs right now.

Not bad at all. A little issue right at 60Hz. Wonder if that is ground hum from the 60Hz power? I doubt that it is audible.

Now on to the tough one, the ETC.

I'm using REW for first time and still running through setup. I'm not at home, So excuse me if I mistate something. I am using the step by step guide. It states to set REW output level to L+R+sub under preferences I think after measuring pink noise, and then increasing volume on avr up to 90db. Problem is I don't see that drop down menu for L+R plus sub. It has numbers on output, and the first one has subs and rt front, number two has only left front and subs, number three has no out put...I'm kind of sick how to get both fronts and sub outputting at this point. Remember I'm still in the setup stages.

IM trying to set the "REW Output, "L+R+ Subs." Ido not see anywhere fo rme to do that. Under REW PREFERENCES

Hi Jerry

One question, where is the recommended place to buy MiniDSP UMIK-1, from MiniDSP $75 or from Cross-specturm $100? One is w/o calibrated one with calibrated. Is UMIK-1 better than dayton UMM-6? Thanks.
