Hello, I'm having trouble understanding and diagnosing my tweeter's impulse and step response. The negative peak seems to be greater than the positive, and the positive seems to be split. This was measured using a UMK-1 3 inches away from the driver. I'm unsure what to make of it, whether...

Hello friends, First of all, this is my first post in this great community, so treat me with love. I have started, so to speak, in this world of looking for good sound, I have gotten a couple of equipment to get started, I have some JBL Stage A130, Ampli Fosi Audio BT20A Pro, an IFI Micro iDSD...

Hi everyone - Here is a quick snap and question about Audyssey. I have the app downloaded and have been cutting off EQ at 500Hz as I have read. But... should I potentially adjust my own curve to tame a spike around 600Hz? I know I could just do it, upload and re-run REW to check, but was...

Hi everyone - I recently picked up a Umik-1 mic and have been measuring my room, speakers etc. After level matching and swapping amps (speakers and mic in the same position), I have noticed very similar frequency response across the amps (slightly different), with slight deviations in...

I am new to room measurements, and I am not quite sure how to interpret this. I have compared 3 sets of speakers, positioned at approx the same place (all three are placed and not moved between measurements, so there is ca 20 cm between them): Red: Dynaudio Emit 20 Blue: System Audio SA510...

I moved my subwoofer from my HT to my 2 channel system as an experiment and the rise above 10k Hz is very unexpected (to me). Since I don't have a preamp I used the speaker level connections if that matters, any ideas? Thanks, /Carl

After getting a couple of weird results on my first MMM measurements, I went searching around the forums & YouTube for what went wrong. To save others from gathering various bits and pieces of info from a dozen sources, I decided to publish this quick write-up here. You can use it as a rough...

Hello everyone, I’m trying to measure the TempoTec Sonata HD Pro in REW as an example, as I would like to measure some other equipment in the future. System: RPi4, Raspberry Pi OS (Bullseye), REW (Java), EMU 0404 USB. The output level is set to maximum, 1kHz tone 0dbfs. The input level is -6...

All, I have finally gotten around to using my new C97 II speakers, the UMIK-1, REW, and Equalizer APO. For the relatively cheap gear I have, this is the best sound I have been able to achieve in my house and the Jamo C97 II solved my lacking musical punch problem. I did find what I think might...

I have a question about those who use Audyssey and measure their results afterwards with REW. In short, are my results normal (below)? I'm a newbie on all this, forgive any dumb questions. I have a Marantz SR6015 receiver with three identical Ascend Sierra-LX speakers. (The center is on its...

This thread is mostly directed at @OCA to continue YouTube comment section discussions in a little easier format, but maybe it will be helpful to others. First system I'm working on is my office desktop setup, in a carpeted bedroom that's approximately 4.7m x 4.1m x 2.9m. I live just under...

Hello, I am totally exhausted. I got a Behringer EMC8000 and connected it to my Focuswrite Scarlett. I used this cable https://www.thomann.de/de/cordial_ctm_3_fm_mikrokabel_schwarz.htm Is this the wrong cable or why does just nothing work? No deflection of the microphone appears in REW...

Hello guys! I was wondering is it possible to correct the phase using REW mathematics? What prevent us to use this app potential to get rid of excessive phase elements in our measurements and get nearly perfect FIR filter which then could be used in Roon or Equalizer APO? Of course there is...

Hello, lovely people. I have a small YouTube channel that focuses on car audio measurements and testing. Since I joined SQ (sound quality - opposite of SPL) community, I realised that a lot of car audio is based on myths and fairy tales from "back in the day". My goal is to start fresh and test...

Hello, I did some analysis of my 2 channel setup, soon I would also like to use it as a theatre setup also. Room is a 12x16, there is a serious destructive interference between 45hz and 60hz, I think one way to solve this is using 2 x Subwoofers. Let me know what you think ? Here's a...

Hi, how can I put two graphs in REW and visualize only the difference between them. For example: Graph 1 has +15dB at 5kHz, Graph 2 has +10dB at 5kHz, the difference should display +5dB at 5kHz. Thanks in advance! :)

Hi again ASR community. Some time ago you helped me a lot in this thread Since then I have changed my audio setup and now it is KEF R3 with Lyngdorf TDAI-3400 streaming amp. Below please find the measurements I did using REW and UMIK-1 mic with RoomPerfect enabled (Lyngdorf room correction...

I currently have the XLR output of the Gustard DAC going to a Buckeye amp and it works well. The way I integrated the sub is with high level (speaker wires) since I don't have a receiver with LFE output and DSP room correction and speaker volume adjustments. I have the sub crossover dialed in...

The other day I mentioned elsewhere this wonderful video by @OCA. It covers many topics but it has one little trick that is so genius that I think it deserves its own thread. In short it is to make Audyssey believe that there is nothing to correct about your speakers and your room. This turns...

Dear All, I've bought a MiniDSP nanodigi, 2 8" subwoofers and a UMIK-1 and I've been experimenting with them for 20+ hours now. For my latest configuration, I have done the following: 1. REW sweep measurements in bass region for each of the 4 drivers for 3 LPs, I used acoustic reference on the...
