Like to follow up with what @Sonnie mentioned which was coupled to your question of roll off and sound quality. In general the lower frequencies are strongly influenced by room modes, assuming of course that you are not listening near field. So sound quality is strongly correlated with speaker...

I do have the MiniDSP Flex. Will enter the delay and remeasure, thanks.

I thought that one can only delay, so how does one make the sub earlier by 7.34 micro-seconds?

Here you go. Lower scale of the impulse is micro-seconds, so was your 12 estimate above in milli-seconds or micro seconds? Thanks.

Okay, will try it. Did you obtain the 12ms from the graph?

Can someone point out where the impulse response for the sub starts? I am trying to align to my timing reference (left speaker) Thanks.

What is confusing to me is like many issues in society today, one is either left or right and cannot be both? Part of this hobby for me is the due diligence phase as I learn more and more about the intricacies of this domain. I personally value the use of measurements as are they are an...

I think we all have our own decision making processes and understanding measurements for me is an indication of quality of design and is important and best done by a 3rd party. Whether those design deficiencies are relevant to me or for that matter, perceptible is also important. Finally to...

First step is to select one of your speakers as a reference when doing the measurements. Delays will be visible in the measurement information section but you can go to “Overlays” the “Impulse” tab. Here you will see your measurements and can measure the distance between the impulse peak of the...

Hi Dom, welcome aboard! Post away

Just to confirm, low pass filter for subwoofer to 90Hz with 24 dB/Oct slope. Will re-run measurements with L speaker as reference. I also made the changes in the analyses settings. In listening, I feel a speaker crossover of 110 Hz sounds much better than at 140Hz.

Here is where I am after re-measuring with the filters. I had to delete some measurements as the file is getting large. This will be a great thread for beginners. :)

Tracked it down to a reflection. Thanks. Used pillows behind the mic, remeasured, and voila.

I like the plan. Just wanted to make sure I understood how to action the next step. I did the step I described (impulse alignment) above and then went to the SPL graphs, 1/12 smoothing. The highest, first peak is the left speaker at 50Hz, so I will enter this into MiniDSP speaker/sub HP filters...

Steps to Align: Select Overlays/Impulse, select all mains Select remove IR delays for all measurements Is this correct?
