here you go, Lady Gaga - Just Dance:
the peak is 35-80 but that's before the house curve.
with the house curve it will be exactly at 40 hz.

I doubt if any of us can hear 2 Hz.
Where can read about compressions drivers? Can someone recommend a good (cheap) one, along with a waveguide that can be bought easily?

Borat is starting to = Boring.
Sure, I can find plenty techno or even classical organ music that has super low notes, so what? I have nothing against low bass, I like it. My speakers at large and I like them that way. Small speakers don't really light my fire.
But I also know where most bass lives and it's not at 20Hz. FWIW, the open E string of a bass is 41Hz. All of its other sounds, fundamentals and harmonics are above that.
IMO too many guys focus on the extremes of the spectrum and ignore the meat of the music. I guess it gives them bragging rights or something. Bigger! Lower! Faster! Higher!
So much chest pounding. Yawn......

But PRACTICALLY those pictures look pretty decent, don't they?
Best, Markus
Markus never got notice of this post and I couldn't get the pictures here so I couldn't comment.
Lady GAGA goes all the way down to 2 hz ( thats 2, not 20 ).
Probably a mistake (rumble from a mic), no mixer would deliberately put anything below 10hz on pop music, its inaudible and eats up head room. If your fighting the loudness wars ever db counts.

there was no mic. not even an A/D conversion. the analyzer was running 100% in digital domain form the music file on the same computer.
unless mp3 compression has the ability to synthesize sub-bass somehow ?

not enough sleep.
plus this thread is hopelessly boring to begin with. i am trying not to look at other threads because then i will end up wasting all of my time sitting on the internet.

A 5 string bass goes down to about 30 Hz. I have quite a lot of music where the highest amplitude signals are below 40 Hz.
Surprisingly, it covers quite a few genres.
For an easily accessible example, go here:
Wax Audio | Mashed Media - Appropriated, Re-Mixed, Sexed-Up & Uranium Enriched
Download his "Blue Rigby" track.

No, you are seeing a common compression artifact - specifically, DC offset shift. When a signal waveform is asymmetric - where, for example, positive peaks are higher level than negative peaks - some compressors shift the whole signal envelope so that the peaks do not clip. They do this by adding a DC offset to the signal. The process is signal dependant, so the offset comes and goes according to the music. Strongly asymmetric waveforms are surprisingly common, especially on vocals.

interesting. so in your estimate the real low-end limit of that track would be 25 hz ?

Probably. Was it the original you measured, not one of the many remixes? If so, I'll check it out tomorrow.

i think it was the album version. mp3.

I believe that you are absolutely correct here. There is very little music that actually is symmetric. I have seen some extreme examples or asymmetry before.
One thing we can take from all of this is no matter how great the final system, it will never fix Lady Gaga 😛
edit: unless the system fell on her!

Hmm, well I haven't had a chance to read much of it but the first bit doesn't seem at all fair. There's someone complaining that they couldn't buy a sub-set of a kit from Mr. Geddes. I don't blame him for not wanting to sell little bits and pieces to the public, that would just be a big hassle for little return.
Anyway, I am not convinced that professional drivers are the best fit for every application, but it is undeniable that Mr. Geddes knows his stuff, and has put together a well respected product line. 'Seems like a bit of a witch-hunt going on over there (social audio dist.).
I do not think anyone is convinced that professional drivers are the best fit for every application.
Just like I do not think anyone is convinced that hifi drivers are the best fit for every application.
I think the discussion in this thread has already concluded two obvious points.
1. It all depends on the application required.
2. Its less about driver choices and more about the speaker design itself that makes for an incredible speaker.
Get the facts right yourself, Marcus. Obviously you missed the fact that what I was discussing is Dolby AC-3, the DOMINANT (and default for DVD) audio coding scheme for video discs in the real world and, by the way, rebutting dishonest sales pitches hyping the sad SQ that actually exists on most DVDs and BDs.
lol, AC-3 is DOMINANT?....did someone time warp us back to 2005?
Good morning Doug,
I'm not as sure of this point as you are. It seems to me the masses are moving toward home theater in a box - little satellites and a noise-maker woofer-box crossed over far too high. Would you say that 5.1 is the future as far as listening to music goes? 2 channels seems good enough for mother nature! 😀
Jim
Yeah, it just shows how good Marketing is and how much placebo still controls the audo world when BOSE can make millions 😉
Sorry for replies from posts 20 pages back....this thread took off with discussion. Take a 3 day break and wow, everything is missed.
OT:
Not many, but unlike CD sales the slope of growth in vinyl sales in the USA has been consistently positive over the past few years. In 2008 sales of vinyl was up about 38% over 2007 which was up over 2006 by about 18% or so - at the same time sales of CDs were headed down. Sales of new LPs will probably number well under 2 million in the USA this year, but this completely ignores the rather large activity in used vinyl and the new production of some indie manufacturers that do not fall under the aegis of the RIAA.
I suspect examining the numbers more closely you will find a significant number of those LPs going to people who fall into our niche category of hobbyists/audiophiles who care about sound quality whether it be two channel stereo or multi-channel or HT. (Yes there is multi-channel audio supported by DVD-A [dead?] SACD, and BD on the music side.)
I think the issue of music delivery formats is somewhat superfluous to the discussion? And to most of the industrial world out there our hobby is dead. How much money do you think anyone makes on the collective bunch of us??
Its easy for Vinyl to increase 20%......heck selling 1000 LPs instead of 500 LPs is a 100% increase 😉
Your last point is gold!! Anyone on a Audio forum is definitely in the minority and I keep that in mind every day.
Heck custom HT is a very small section of the market and I find it funny that guys on here that do not even remotely have a good HT setup are mocking it as lower SQ.
If you do not have a great HT setup how can you comment? Its the same arguement as when some on here post "If you do not have a high end setup you will not hear what I hear".....so that arguement can not go both ways?
When you have a higher end custom HT, you will understand that we do not just watch a movie. We experience it and that requires the highest quality setups and we definitely are far beyond AC-3 🙄
I guess we must first decide whether hi-fi and HT is the same or not, before the speaker discussion will make sense. 🙂
Most people that understand its all sound reproduction (music or audio from movies) would never even have to decide because both are all about ultimate SQ.
