Thank you. With new setting I achieved the same resolution frequency. I have one doubt regarding the second and third suggestion: A R speaker with a TW needs to also be connected to the receiver, so if you have the R speaker already in the room and connected, you are good. Now measure the L TW...

OK, thank you for suggestion. I will try once again, in vertical position. However gluing sticky parts to paper membrane might be risky :).

Hi, I don't want to start new topic, so I would like to post here, because it refers also TS praram calculation. Would it be OK? Some values like Qms, Ots are far away from the spec. And I wondering what may be reason of that. I read instruction carefully and I hope that I did what I should...

Thank you. I understood your latest post, but for the same settings I achieve Frequency resolution 833,33Hz and I don't know why. Regarding previous post, I suspect that you reffered to acoustic timing reference measurements but I selected loopback timing reference. Am I right? I'm carefully...

We were writing in the same time :). Exemplary setup is at below picture. I will back to the topic next tomorrow and I hope to be ready do next step by myself. Thank you for your time.

I did simple experiment with new settings. I know that measurement space is limited, but I can't play in big room because my childrens are sleeping nearby. I will do proper measurments at the weekend, with longer distance and speaker disconnection. In this measurement disatance to microphone...

Thank you John. My understanding is that I should us option marked by green arrow, am I right? Should I define Timng offset before measurements or can I do it later on, after measurements in "Impulse" menu as I marked below. Regarding distance to wall and floor I agree, but the most interesing...

I would like to ask you to help me setup REW tool to do phase measurement. Would it be possible? I did it myself but results but are suspected. Topic is not too easy for me, but I would like to do it correctly. The issue concerns two-way speaker and I would like to re-design my crossover to...

Thank you very much for your support and help. The problem was finally solved. Windows Audio setup had the input selected as MONO input. When I changed them to STEREO 16bit, 48kHz sampling, everything worked fine. Now I will be able to focus on my passionate measurements. Thank you for the great...

Hmm. What can I add... I see that input level indicators are always equal. Sholud they show LEFT and RIGHT input channels level? If swap the inputs in the software measure window, mentioned before, there is no differences in result and also on the input meters. It looks like that software can't...

Your results are fine, and I would like to achieve the same :). You asked me, that I should try to change input, from LEFT to RIGHT. Should I do it at the place marked at the picture (red arrow). If yes, it didn't bring any difference in my measurements. They looks similar. I can add that in my...

I appied settings as you recomended. I removed also amplifier. Results are similar. I'm still using UCA202, but some time ago I used Mini DSP 2x4HD as as input and results were silmilar. I did the new calibration without amplifier and new results I presented in attachment.

Simplified schematic was presented below. For second group of measurements inputs were swapped.

All measururements were done with using small amplifier to ensure low driving impedance. Rsense = 100ohm. Details of each connection were descibed in .mdat files. Thank you for your time.

OK, I cleared calibration by clicking two buttons as on below picture: Next I measured impedance for correct input connection and next for swapped input. Results are presented in attachment. When I changed Rsense to 100ohm I obtained similar results. When I selected SPL measurements resulst...
