Hello fellow madmen (and hopefully the occasional female), I have lately been, rather intensly, watching the great Youtube videos of "Obsessive Compulsive Audiophile" (user @OCA ), a by now well-known Frankfurt genius :) He shows in detail how to correct for speaker/room deficiencies/influence...

I recently built an extremely strange room in my studio with dimensions 16’ x 8ft x 6ft. I have about 5inch thick acoustic panels on all sides. The goal was to see if I could get something that acted anechoic without caring about frequency response/bass buildup… almost like a radio booth...

As you can see from the attached graphs, switching to L+R from L only changes main speakers' measured SPL but not subwoofer's on REW measurements. The subwoofer is SVS 3000 Micro, connected to my KEF LSX II LT via its subtout. I don't think this behavior is normal. Denon AVR-X3800H, which is...

Hello All, I am unable to decide on the placement of centre channel. I am keeping the centre channel of top of TV cabinet and moved it edge of the cabinet. I even raised little bit with door stoppers so that it will be pointing to ear height. Today i took measurements with REW and i see that...

I have a spare TacT Mic. I was wondering if what device I need to connect to the computer to run a REW software scan. I am just weighing if I need to buy a UMIK-1 or this converter for REW software. Thank you.

I am a big fan of Equalizer APO/Peace which I use for a long time. Only a few days ago I started with REW as well. I can play with REW, and for example use the "Audyssey One Evo" script (for Audyssey calibration on my AVR), and among many things that the EVO script does, it enables me loading...

I'm currently trying to figure out how much room gain i get in my "casual movie watching/gaming room", so that i can choose a fitting subwoofer for some infrasonic Bass, when I've got some money saved up. My room is 4.5m x 2.7m x 2.5m -> Room Gain should start at ~38Hz. My Though process was...

Hi, I got myself a pair of subwoofers that I'm trying to setup together with my main speakers. B&W 804d2. Subwoofers are B&W db3d and db4s. I have started out with just 1 subwoofer the one I got first db4s and try to find proper phase and volume together with my mains. The orange line is with...

where can i find the measurements (REW) of the best studios in the world, pre and post acoustics, pre and post eq i have my room measurements and want to compare data like clarity and rt60 and more. above all where can i find the expected ideal listening room measurements / settings to be such...

I have a MiniDSP HTx with full range Dirac Live license. I am using it to drive a 2.1 system at this stage via toslink input. If I use REW to generate 10 PEQ’s for the mains and do my best to phase align my sub I cannot seem to get a good result. I have conducted 1000’s of MMM or sweep...

Hi, Recently I bought a second subwoofer for my stereo setup and I want to ask you about proper measurement process to get things optimized. The setup consists of KEF R3 speakers and two Arendal 1961 1S subs crossed at 80 Hz. Amp is Lyngdorf TDAI-3400 with DSP room correction built in. The...

Hi everyone - I have a quick-ish question, which might take longer on the answer. In my HT, I have a 7.2.4 setup. I have run and re-run Audyssey calibration a ton of times, moving things around. After calibration, I run REW and check the results. I have noticed that I have 5-10db dips in the...

I am using REW + UMIK-1 for room EQ of my office setup, which is based on RME ADI-2 DAC fs + Neumann KH 80 DSP. The 1st 2 bottom lines were done using MMM: pink noise on generator, RTA with 32 samples. The 3rd and higher line is a single measurement holding the mic roughly where my head...

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...
