frequency response

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...

This thread is intended to consolidate the technical discussion and further development of Scott Wurcer's frequency response measurement script to a central area. I'd like to keep this discussion about the tool rather than specific cartridges. I'll edit this and the subsequent reserved posts in...

Hey guys, I've spent a lot of time Optimizing my Speaker Positioning using REW and after weeks of tweaking my current set-up has the following psychoacoustically smoothed frequency response at the listening position as measured by a Umik-1 microphone: As you can see I've got a...

Hi Everyone! TLDR; what's your preferred FR Curve and EQ goals when using DSP? I've built my own pair of speakers of my own design, you can find my write up of it here: Still Haven't Named Them. I stopped messing with them for a bit and am very happy with its sound signature except I found...

I've been obsessed with headphones measurements for years, specifically with frequency response measurements. But, I am yet to find measurements that match with what I actually hear. More specifically, none of the measurements match with what I hear when I run the SineGen. They are accurate up...

As the title says. Are there Golden Ears measurements archived somewhere, the way Tyll's Innerfidelity ones are? Golden Ears measurements were THE best, and the most accurate I've ever seen. Unfortunately, the site is long gone, and using the Wayback machine is not smooth at all, plus a lot of...

Hi wonderful audiophile people, so nice to have such valuable info and feedback on this forum. Been researching speakers that go deep in low frequencies and found discrepancies across both tests and specs. Notably about mean on-axis levels as well as frequency response range. 1. How can a...

Hello, I was wondering where would I place the panel on the celling, it is a slanted celling which goes (Short to High). How would I calculate the first reflection point, my guess would be between the centre of the listening position and the speakers. Also would the panel be Vertical or...

Hello, I am new when it comes the room acoustics, I have been mixing in headphones most of the time, and now I would like to start mixing on speakers , I have set up my speakers and my best listening position in my room, it is a small room with a slanted roof. I have ran some test on REW with L...

Can you hear the differences in the jumps clearly because they are on a small db? What about 80 db? Does it get better with EQ, because I've never tested it, but some said the highs were pitched too high without eq, but with eq you lose clarity (3350 hz, clear jump up)

Does anyone have some example measurements as to how typical speaker FR changes with volume? I know that Amir test speakers at 86dB and 96dB, but how does it work at low volume? The reason that I am asking, is a discussion I've seen on which speakers/hifi equipment sounds best at low volume...

Dashed Lines are the original and Amir's Harman targets, exactly the same for the most part. (Thin and thicc (respectfully)) Solid Green is the Aeon RT (Flow Closed) $500 Solid Red is the Closed X with the single notch filter $380 Solid Blue is...

Hi, I'm looking to purchase either the Sanken CO-100K microphone, or something similar, to capture material for sound design. The main reason being that it will enable me to capture high frequency content and have this preserved/revealed when pitching sounds down inside of my DAW. Nothing super...

Hi, I wanted to know you opinion on cutting frequencies below 20 Hz, I saw a lot of speakers that have small woofer that doesn't extend well past 50-60Hz, but that's not the case with headphones, with many reviews recommending equalization of bass to Harman target and even with linear bass...

Are they meant to sound this way? Like the measurements below, they are pretty dull on the high end. Do the measurements look like they're broken in any way? If they're not (both speakers measure similarly), what could the consideration be for such a sonic design? I've no idea what generation...

There has been interest in this thread over what the Apple music EQ presets (on iPhone / iOS) are actually doing, in an effort to use them to correct headphone responses without much inconvenience. To access these settings on your iPhone, you simply go to Settings -> Music -> EQ. The EQ is...

In my search for great transducers to EQ and enjoy music with, I have found some brands better than others in objective measurements such as frequency response, distortion, resonances, etc. I always found Audeze’s transducers to be extremely good to EQ, even when being open-back. Their only...
