trying to figure out the overlay.

The overlay is under "All SPL" and you can check the boxes of which measurements that you want to see.
But all of those measurements should be from 20Hz-20,000Hz. So, measure the sub over the full spectrum, then measure the speaker over the full spectrum. Then measure them together over the full spectrum. It looks to me like you're measuring 20Hz-200Hz for one then 200Hz-20,000Hz for another. That's not helpful to see if there are any problematic interactions between your subs and main speakers. Getting the phase right is important before you EQ the system. Though I do fully support the advice that Tyson is giving. He is spot on. But some of the problems in the low end could be phase related so it would be good to iron those out.

This is an example. I measured the whole speaker, then measured just the lows of that speaker and just the mids.

Thanks for that. Very helpful. When my wife heads out I'll take some more measurements. Appreciate it fellas.

Crossed a bit higher. I'm maxed out @120

Close but not quite.

What you want to do is run all sweeps from 15Hz - 20kHz. The resulting graphs will show the rolloffs of each section independently and the sum when the full speaker is played

Bit more FR volume.

another look crossing near 220Hz 1/12 smooth

Suckout @ 193Hz. Room issue?

No. That's showing the sub is out of phase with the main speaker. Adjust the phase control a half turn. Then do another sweep measuring both the sub and speaker. If the speakers are now summing properly you got it. If it is moving in the right direction, adjust the phase control another quarter turn in the same direction. If there is now a hump at the crossover point, turn the phase control a quarter turn back towards the starting position. Take another measurement and keep adjusting the phase until it sums properly.

You may have to fiddle with the crossover control also.

Phase adjustment only. haven't toucher crossover, yet.

mkane · « **Reply #51 on:** 22 Oct 2021, 11:40 pm »

Crossover adjustment applied. Crosses @ 166

Don't know why is continues to show 10 db increments. I snap the pic @ 5.

mlundy57 · « **Reply #52 on:** 22 Oct 2021, 11:42 pm »

It looks like the phase adjustment is moving in the right direction. Is there any more room for adjustment in that direction?

mkane · « **Reply #53 on:** 22 Oct 2021, 11:51 pm »

just a few notches. If it makes any difference I have the wedgies flush with the front of the H frames and in the center.

mkane · « **Reply #54 on:** 23 Oct 2021, 12:24 am »

Maxed out on Phase & crossover.

I haven't installed no-rez in the H frames. Next week when it not raining I'll get the table saw fired up.

mkane · « **Reply #55 on:** 23 Oct 2021, 10:25 pm »

No-rez installed.

Now turn the PEQ on and pull that 50Hz peak down. You will have to play around with the frequency, width, and cut settings

mkane · « **Reply #57 on:** 23 Oct 2021, 11:43 pm »

I'm thinking it was on. Frequency is @ 80, bandwidth straight up. No idea what cut is.

You're getting good advice from MLundy. But these two readings are drastically different. It looks like you turned up the volume of your subwoofer or changed the mic position. The previous reading, where the 20Hz-200Hz region was flatter, looked much better. I doubt that No-Rez would have changed that. Did something else change? This reading has a huge peak at 50Hz and the other one is flatter, but seems to have a lot less around 35Hz and below.
Also, are you crossing over the main speakers to cut out the bass? It looks to me like it would be useful to lower that frequency if you are.
But these readings seem to have the subwoofer and main speakers more in phase, which means that we're getting closer.

mkane · « **Reply #59 on:** 24 Oct 2021, 10:33 pm »

I messed with bass volume. I'll go back to the previous settings. Measurements take @ 1 meter.

I also printed a A370PEQ Settings sheet from sticky's so I don't get lost.
