frequency response

Hi everyone, I have read already starter guides about how to measure the FR for IEMs and ordered the equipment for that purpose. However, many things remain unclear to me. I succeeded (partially maybe...) with my first FR measurements in REW but somehow the lower end seems to be off when...

My Questions and a link to my measurements are at the end of this comment. I've got a 2nd SVS SB-2000 today for my small, well sealed room (4.5m x 2.7m x 2.5m) - It sounds amazing, but now I'm in for chasing the last few things I could do better just for the fun of understanding new things and...

Introduction On August 15, 2025, at the 19th Shenzhen International Audio Show held in Shenzhen, China, Moondrop introduced two new planar magnetic headphones. Moondrop is a brand widely known for its well-tuned, neutural sounding IEMs with cartoon child figures printed on the package of...

I have my Studio Monitors with a Subwoofer calibrated for the flat frequency response + a little bit of personal taste. I have been listening to different genres of music and I have been jumping between Electronic and Rock/Metal music. While I have been listening Electronic Music I haven't seen...

Hi, I was looking to buy a my first 2.1 system (+Wiim for EQ) but after researching for weeks, does it even make sense to buy speakers if you want a flat frequency response? Ignoring the question of what is a flat target curve, is it even possible to hit any curve below 500hz with the way room...

Hi, As a result of cancer treatment I suffer from hearing loss of different frequencies to various degrees in both ears (up to 50db). Consequently, music and audio sound abnormal and lifeless I desperately wish to listen and to enjoy audio again I am hoping someone can recommend a way to do...

Just a few months ago I bought a pair of JBL LSR305 studio monitors, and they sound amazing. Everything is super detailed and there's no distortion. But they seem to be too bright (likely due to room reflections) for my taste and don't sound as pleasant as I'd like them to. Is there a frequency...

What is the mechanical reason for this?

Hello everyone! Amirm is often commenting in his headphone reviews about how equalizing a headphone changes its spacial qualities; suggesting that the perception of space/soundstage is importantly dependent on frequency response. A question comes to my mind. Let's assume two almost identical...

The frequency response in this D9.2 review looks weird. It is also different from the frequency response in magazine reviews of the previous version D9. The high is much elevated. Frekvenční odezva - v ose (červená) a pod úhlem 30° (černá) (Bing translation: Frequency Response - Axis (Red)...

Hi. I have seen many posts and articles where they show how to analyze and get flat response curves for speakers. However, none of them show how the frequency response of a well treated room looks like. Then I found this video: And from what I understand is that, flat frequency response studio...

So, I finally have a proof?? I finally have the ultimate answer to the ultimate question?? (Go to bold for the resume) Hi, everyone, since I'm an engineer i don't really believed how a cable might affect sound, i mean, YES there are all types of cables and some are for specific tasks, such as...

Below you can see two raw FR graphs of two separate headphones, measured with the GRAS measurement rig that was used in the preference research, plotted together with Harman AE/OE target (green) alongside the error curve (red) showing how much they deviate from the target for each frequency...

Hi, I am currently planning my studio, my room is 18 m2 and the setup is on the shorter wall. The room is reasonably symmetrical except for the windows, but there are none at the first reflection points or backwall. I made the first measurements in different positions and distances of the...

Hi! This is just a question - is there any measurement done with the 5128 rig for the Philips SHP9500?

Skip to the index. After years of development we are finally launching our phono cartridge measurement library. These measurements were created using the brilliant cartridge response python script, SJPlot, written by the legendary @scott wurcer and @JP. Information about its origins can be...

Following recent discussions with helpful members of this board, and finding the Youtube videos of Julian Krause very informative, I have concluded the preliminary investigation and equalisation/correction of my JBL 104 BT desktop monitors. My methodology was to purchase and install a...

Hello ASR, this is my first attempt posting something here, so I'm sorry in advance for mistakes that I could made. English isn't my primary language so I'll try keeping things as clear as possible. I've been in "read-only mode" and recenly realised that I gained more knowledge over this year...

Is there a measure of a speakers ability to play multiple tones at once? My understanding is that FR data is generated by sweeping through frequencies, only asking the speaker to produce one frequency at any given time. Is this correct? To me, the ability of a driver to produce multiple...

I just bought a pair of KEF Q950’s and was wondering what the meaning of the “Frequency range Free Field” specification is. It says it is 38Hz for these speakers in the manual. Here is a link to the manual: https://assets.kef.com/uploads/cm/Q_Series_Manual_EN.pdf It also says in parentheses...
