Something I made this morning after browsing youtube and discovering how many people like to record youtube videos of woofers being overdriven to this goofy song "Bass, I love you."
Support my movement against cruelty to loudspeakers!
Edit: Would help if I included the URL I guess.

Just doll and boring, but great looking setup.
What I where hearing was my fone's speaker, and that was not a lot of fun.
would have loved some xlim porn.

Yeppers, it is, thanks!
I'm still working on it, I need a couple more coats of paint and terminals in the walls so I can hide all the wire, plus the 2 front subs are being replaced with a pair of ficar ib318s soon.
I might make some xlim porn after I get the new IB subs going, but I'm usually very careful about not clipping amplifiers, so it probably won't be impressive by youtube standards, haha.
Please do, then youngster can see and "hear" (using there own speaker) how its sounds.

I'm using studio monitor headphones KRK KNS6400.
I must admit your video sounded nice but..
..then I played the original song and I could hear NO BASS!
I was surprised so I viewed a bunch of other sub "tests". Others sounded horrible with the exception of a Rythmic sub and a KEF speaker which again had NO bass but plenty of excursion.
I hope I'm wrong but the only reasonable conclusion is that the bass on this track is inaudible and your system produces a great amount of harmonic distortion.

An externally hosted image should be here but it was not working when we last tested it.
I placed the mic in a spot in the room which exaggerated the bass a little bit. I've got the volume down very low in the video, it's probably running on less than a watt, so it seems implausible that there is enough distortion that it would be audible, especially over the fundamentals.
Did you play the "original" from youtube or did you actually purchase the disc or download a lossless copy?
Edit: Attached a frequency analysis of the mp3 I have of the song. I've used "hold" in two places to see what the 2 dominant notes in the song are.

I played this YouTube video
Bass, I Love You! (Final Version) - YouTube
I shouldn't say that I hear NO bass from the song, there is some bass but it's faint and not coherent like it is in your video. Material below 20Hz should be inaudible.
Transmission line speakers can reach high excursion for signals below the tuning frequency even at moderate levels.
That's a different version than the one I have. My rear subs are actually a T-TQWT which will unload below the tuning frequency as well, but I'm usually very careful and for computer sources (like the media center I played this song through) I have subsonic filters enabled.
Edit: You can tell how quietly I was playing the song, at the very beginning, you can hear the "click" of me carefully closing the door to the other room which was about 3 feet from where I had the mic.
I have just tried a couple of youtube vids, and the better the quality the deeper the bass. Saying anything about the sub level on the original can't be done by viewing youtube vids
Right, which was the point of it all to begin with. Make a video that illustrates a subwoofer playing the notes rather than video it like Federico Fellini while it's being destroyed.
Here's two screenshots. One is the analysis of the source file while shows the notes, the other is an analysis of the video I took. The notes are the same frequency. The analysis of the video shows how I positioned the mic closer to one of the subs so it's a little bass heavy, but that was the point.

Your recording sounds good and makes my 15", 3 cu.ft. sub sound great. Your recording filters out the subsonic signals in that song except for a slight bit of cone movement. Even with 1 watt, it is amazing how much cone movement there is on ported speakers at below tuned frequencies.

I tried bass boost on my headphones and that made the song sound more like DrDyna's video.
It sounds most similar with a 15dB boost at around 40Hz. I was wrong to automatically assume harmonic distortion.

Thanks B 🙂 One of these days I'm going to have to get those spreadsheets and learn how to use them.
It is! I usually don't play any games in the big room unless I've had a few drinks though, haha.
