Sorry AlexF40 for not replying sooner. I do believe they are aligned at this point, however, I have not verified it with the impulse response. I am basing it on the substantial improvement in bass I am hearing. See if the link below is helpful.
Are you familiar with REW...
Yes, I do understand, now. All measurements are relative to the reference distance.
Ok, I have taken more measurements. I adjusted the FR and FL to the same distance. I took a dozen measurements of each and was still getting a couple of variations in reference timing. I am still at a lost why...
Sorry for not responding sooner. I had to sleep on this to try to digest what you were saying. My take on it is: it is essential that FL and FR distances are the same as measured by REW. Equal main distances will permit proper alignment with aligned subs. And, if the CC distance is the same as...
The speaker distances are:
CC = 17.18ft
FL = 16.63ft
FR = 16.34ft
It agrees with your statement and are also in the ballpark of the timing reference figure. These distances are set in the processor during measurements. Should they not be?
You mentioned a "well centered mic". What do you...
I have taken new measurements of mains and subs. I took several of FL and FR. There were a few things that stood out to me.
1. The timing references showed negative delays and with some variance. They should always be positive, correct? What tolerance should it be for a speaker, +/- 0.05ms? The...
Can you offer some things I might check? I have done several measurements in the past, all in the same manner, but this is the first time for the recommended delay be placed on the closer sub.
Thanks for the link. I will read it to try to educate myself more.
No, experimenting is definitely my...
Thanks so much for taking the time to look at this.
Adding delay to the left subwoofer is counterintuitive since it is further from the MLP than the right. So, does that mean the best delay will not always be a function of subwoofer distance?
In choosing your recommended 14.5ms left sub delay...
Hi,
I posted this in another thread but did not receive a reply. So, I am trying it in a new thread.
I have relocated one of my subs, so I am trying again to align my two subs (HSU's; one ported and the other sealed). I have an Emotiva UMC-1 processor, with a 5.2 setup and minidsp 2x4HD. I...
Hi, it has been a while since I had a chance to get back to alignment, so I apologize. Emergency eye surgery and not allowed to use my computer for a couple of months, holidays, etc.
I have moved one of my subs so first, I am starting again with trying to align my two subs (HSU's; one ported...
Ok, I eq’d both subs. There is a substantial improvement in sound quality. Bass is more robust, tighter and really thumps.
Thank you so much!
For sub/main alignment:
measure each sub w/o any delay and with xover
measure FR and FL individually with xover
use center for timing reference
sum...
Thanks for your help. I buried my other response inside the quote portion of my previous post. Did you see them? Still learning post presentation.
Did I do everything correctly? Am I ready to move on to main/sub alignment Is the procedure the same?
I think I followed your instructions. I really don't understand the alignment tool. When moving the sliders, it appears that there are several different delay values where the graph looks good. So, how do you know which value is the best?
Also, what information is the phase plot telling you?
I...
Okay, I got a window and took some measurements. I would like your input. I measured both subs individually and together per video. Looking at the measurement results, it looks to me that the better responses are the "inverted" response and the 11s delay response. I have attached the mdat file...
