I've seen this page, I even had some of his difussers. Not sure about the traps position suggestions. The most effective absorption occurs where the sound pressure is highest – and this is not always in the corners. While corners do tend to accumulate modal energy (since sound waves from...

Not quite sure but I can move the pic around and see what happens. Seating position is flexible as the room isn't yet finished. Moving it in the simulator doesn't do much. I spent some more time in the simulator and noticed a really interesting phenomenon. The graph "sim11" uses a parameter of...

Hi, fellow audio friends, I recently had to say goodbye to my beloved old room and am now starting fresh in a new space. I’ve done some early measurements while the room is still mostly empty. There’s no acoustic treatment yet. Just exposed (unfinished) walls to allow access to the primary...

My room is currently under construction after moving into a new house. For now, the equipment setup remains unchanged: 4 Velodyne DD-15 subwoofers Auto EQ via Audyssey for movies Manual timing adjustments for stereo (with a lot of help from this community, especially @jtalden)

An amateur question. ;) May I ask where MultiChannel Mic Array can be helpful in home rooms? So far I've been measuring one channel at the time ...

Many months have passed and this is still a superb setup. I did nothing but enjoyed since this awesome learning lessons. I guess I needed some time to adopt because I see now that low frequencies are more detailed when it comes to movies. Thank you again, @jtalden!

Here's the Harman Curve in case you'd want to import it in REW.

We may not pass but we are sure much closer than before! I'm really glad there are many good people who are willing to help. I focused on multichannel sound lately. Not sure if I need some time to adjust but sometimes I feel like something isn't as it should be at low frequencies. I suppose any...

Oh, I'm not analyzing. I'm making notes so I'll be able to repeat this process some day. Hopefully all by myself. I believe there could be an universal rule. Measure L, R and each sub together. Then: 1. (A+B)/2 for mains 2. time align subs with alignment tool and sum pair if necessary 3. sum all...

So the proper thing would be to use trace artihmetic A+B (instead of (A+B)/2 for step 6? I compared the A+B and (A+B)/2 and I see the sum only 6dB hotter. Did you made the same mistake for mdat in post #68 or are we talking about post #89? Because I liked the sound immediately when your...

Not sure if I follow. The way I see it you used A+B average for plot SX4 (looking at mdat from post 89). If you would have used just A+B it would not be marked with the sign "Trace Arithmetic A,B average", right? I repetead thisprocedure today and got the same result as you did. * Or are you...

OK, much more clear now, thank you. This is really helpful and can save a lot of time instead of doing trial and error experiments. Couple of questions though: 1. I see A+B, (A+B)/2 and average look pretty similar except A+B is louder. You used (A+B)/2 for all actions, I assume this is the best...

Great, this is really helping me learn very useful functions of REW. I tried to play with 2 sub pairs but didn't succeed. I included mains of course (I used trace arithmetic A+B for left+right speaker). I shall practice more, I guess. ;) What is the difference in trace arithmetic tool between...

I see, thank you for the explanation. Yes, listening is important, I've spent too much time looking and relying on plots. Did you use alignment tool along with impulse plots? I tried to use alignment tool with average plots (two subs pairs) but looks like this can only be done for single sub...

Based on my previous attemts phase changes from 75 to 105 didn't make such huge differences. Anyway, I like the first option and now it's time to enjoy listening! ;) Forgot to mention. Tried EQ too (can be seen in mdat file). Interestingly, it is far away from REW predictions. However, I'm...
