Turns out one sub is defective and for 2 months did not hear it with my music and volume. It rattles between 20 and 27hz. I can get it to rattle at full volume and tone generator.
Hope my dealer which is in Egypt and is not an official distributer, csn fix it. My bet is something needs tightening. Anotherthing when i put tone generator at full volume for a few minutes a plastic burning smell comes out.
The 7hz zero 2 has clean bass down to 20hz or lower. I have foam ear tips with it.

You're not supposed to run tones at full volume, let alone for multiple minutes at a time. You are causing damage to your equipment.

Noted thank you.
 
Just discovered her, and WOW is all I can say. She has some amazing material. So good, you forget she's topless. I found a new rabbithole of music to check out:

I've got the following CD from her (Chaleur Humaine), and I think that's a really good albumn, it was released back in 2015, but I bought it sometime in 2020 or so, but I've not really seen what else she's up to since then.
I did find out though that she now identifies as he/him. She's not trans, I think I read that she doesn't want to alter her body in any way. No, but anyway, I've had a look at that vid you linked and it's alright music, I should check out what else has been released, and maybe I'll buy some more CD's to rip.

EDIT: for some reason at the link I linked the songs are in French, but I've got the albumn that is mostly sung in English (different versions).

I'll look into for sure. From what I have seen, I need to see more. She's gone more pop/techno stuff these days and changed her name.
 
FYI, as someone else mentioned:

Héloïse Adélaïde Letissier, known professionally as Rahim C Redcar, and formerly as Christine and the Queens, is a French singer and songwriter. Born and raised in Nantes, he started learning piano at the age of four and found inspiration in one of London's clubs while studying.

And...


There are some musicians who seem made for, and by, their work, who make music that lives through them, from their toes to the tip of their quivering quiff. Redcar, formerly known as Chris, also known as Christine and the Queens, and born Héloïse Letissier (a name he still occasionally uses), is one of those.
...
Red takes his music seriously, but his mother’s death also plunged him into a deep grief, which ebbs and encompasses, and led him, as death will, to a search for meaning in life. It also helped him to a new freedom. “When my mother was alive, I think I had to be a daughter for her,” he says. “And, by the way, I loved her, so I was not super mad [annoyed] about this. But there was a huge chunk of me that did not even connect, I think, to my trans identity when she was alive, because to be feminine was an element of what she needed also.”
...
He often uses different characters and names to locate himself: Christine and the Queens and Chris are an expression of where he was at the time. Chris was a sexual woman playing with masculine identity, while Christine and the Queens came out of his blossoming away from being a serious music and theatre student in Paris, through hanging out on the London drag scene (hence “and the Queens”). “Christine, when I picked Christine as a name, it was a joke,” he says. “Christine was a name I was using for everybody, like ‘darling’. And my intention was that that name could be used by everybody. A concept that I was using for myself, but it was really not that personal.”

...
Redcar is another iteration, then; in his first Redcar video, for La Chanson Du Chevalier, he plays a sailor, limping because of his leg...”

He, she, her, him, blender, I don't care if they're making good music. Seems to me from an interview the new persona is more similar to David Bowie going through his androgynous Ziggy Stardust phase than anything.

It's complicated, I suppose some people have to let themselves go through this, if the music's fine that's all good.

I've got that albumn, I like it. I wanted to say that I first heard Spring 1 in either a Doctor Who episode that was during a Winter Fair on the frozen Thames river in London or was that a scene in another program or film or was it in the film Aeronauts that I heard it first. But after googling it then I think I must be wrong, but for some reason I have this picture of a Winter Fair on frozen Thames river (in what would be pre Victorian times now I've looked it up) and/or Aeronauts in my minds eye associated with that!

A nice smooth-jazz album for bass (low Fq) and higher Fq tonality check and tuning

I hope it would be allowed duplicating my post #63 on the thread "Music For Testing Bass" again here in this post on this thread...

Just for all of your possible reference and interests...

As I have shared here on my project thread in September 2022, I have (almost?) all the CDs of Peter White (smooth jazz, acoustic/electric guitar player), and I incorporated a few of his wonderful tracks in my "Audio Reference Reference/Sampler Playlist" (ref. here and here).

I assume, as "a whole CD album", Peter White's "CONFIDENTIAL" released on March 23, 2004 would be very nice reference/sampler for not only bass (low Fq) tuning but also the total tonality balance over the whole 16 Hz - 22.05 kHz CD format frequency and dynamic range.
WS00007068.JPG


You can hear the entire album on YouTube in rather good sound quality, even though I know nothing about sound compression in YouTube clips and your YouTube listening internet environment and your audio gears;
https://www.youtube.com/playlist?list=OLAK5uy_kQxYlSsNL89etmxdvOEFprKf8xWYrEmQY

Just for our possible reference, I have quickly analyzed two tracks of the ripped CD album using Adobe Audition 3.0.1's 3D(Gain/Fq/Time) color spectrum and FFT frequency spectrum.

First, track-06 "Lost Without Your Love";

WS00007069 (1).JPG


In the FFT frequency spectrum of the whole 3:35 track, you can clearly observe (and hear) the distinct high-level low Fq sound peaks throughout the track where we have well separated low Fq peaks at 35, 39, 44, 52, 58, 69, 78, 87, 97 and 103 Hz!

I believe you (we) need excellent L&R subwoofers and woofers, both have nice transient behavior with precise time/phase alignment with each other, and nicely tuned DSP-based multichannel multi-amplifier setup dedicatedly and directly driving subwoofers and woofers; furthermore, the amplifiers driving these SP drivers need to have excellent damping factors.

Here, the distortion in woofers caused by overlapped lower subwoofer-zone transient sound should be minimized by appropriate filters in DSP configuration (and built-in filters in active subwoofers).

Four the total tonality tuning of this wonderful track, I assume independent flexible gain tuning for subwoofers, woofers, midranges, tweeters and super-tweeters would be needed in DSP domain and analog domain (e.g. ref. here).

Part-2: using a typical reference/sampler music track suitable for mainly checking and tuning of low Fq (bass) transient music sound as well as total tonality Fq-SPL balance all over 15 Hz to 22 kHz #975


Second, track-08 "Swept Away";

WS743.JPG


You would please note, in 0:40 - 0.45 portion, we have "meaningful" very low Fq sound over 16 Hz - 27 Hz even though the gain is not so high. I can clearly hear and feel (by my whole body) the 16 - 27 Hz sound by using the big and heavy L&R subwoofers YAMAHA YST-SW1000 (ref. here).


Details of the latest setup of my DSP-based multichannel multi-SP-driver multi-amplifier fully active stereo audio system can be found here.

Just for your possible further reference and interests, I also have started these two threads relating to audio reference/sampler music playlist; your visit and participation will be much welcome.

Those tracks sounded good on my stock Sennheiser HD560s New Version headphones, I got all those bass distinctions in that first track, which is literally just from the bass guitar (EDIT: although fortified to a lesser extent with I think a kick drum that strikes at the exact same time as some of the notes of the bass guitar, but the bass guitar has stronger presence). I also heard that low bass "drum splash" at 40 seconds in that second track, but I don't think I really got the 16-27Hz content as for a start that is at significantly lower level digitally in that track according to your graphs. I listened to the Youtube versions you linked, I reckon that was pretty good quality recording & playback, it all sounded very seperated & distinct, I quite enjoyed it!

Some serious shit:

Nice, I like that, made my head rock! Sounded very good on the same stock Sennheiser HD560s New Version headphones. I found that to be a really good soundstage track too, felt like there was a lot of depth to it. Nice.
 
, but I don't think I really got the 16-27Hz content as for a start that is at significantly lower level digitally in that track according to your graphs.
The sound (16 Hz - 27 Hz) at 0:40 to 0:45 on the track "Swept Away" is, as if, low-gain "distant thunder" sound naturally recorded or artificially synthesized.

I believe we need excellent L&R sub-woofers (and amps driving them) in acoustically well-treated listening room for nice reproduction and feel/perceive not only by ears but also by our whole bodies for that sound!:D
