Speaker sensitivity vs SQ

You don't have to have a highly efficient speaker to overcome dynamic compression in normal usage. As the article points out, there are methods of voice coil design, speaker design, material choices, etc. that can all mitigate these problems, hence probably why there are 100's if not 1000+ speaker designers, but very few professional driver manufacturers, and why top speaker companies design their own drivers.  It is also a reason why active speakers will be necessary for the absolute in sound recreation.

I've just thought of a new product:  A voice coil fan!! Gotta run patent it!

See you all in Colorado!!

Reproduction of sound/music, is NOT the same as creation of sound/music.

Ok i will not answer to all your distortion of my points...

Except these one...

Pure "Reproduction" of sound/music is IMPOSSIBLE in practice... It is a path where each foot is placed on diverging choices.... The management of these choices are what i called a "recreation" of what was a musical creation in a living stage or room...But you dont answered that point at all...You only call me ignorant  like it was an argument....Recording engineer by the way are not only scientist but artist for this reason...

I cite Toole about reflections and someone who contradict him, just to relativize your own DOGMATIC affirmation that all primary reflection are bad... You distorted my intention like usual..Read your own posts before answering me . Or keep a red string in your head....Even late reflections can be good if wisely used by the way...

I contested not, the fact that nature lack walls and reflections, 😊 but your false assimilation of nature and an anechoic chamber, remember?.... Here also you distorted my intention...



I will let you with a tidbit to pounder also with the same arrogance you always keep with any " ignorant audiophile"...

Why do you think speech is badly perceived in an anechoic chamber?

A clue: Most headphones have ALSO a room with reflections...This is their shell....

I already have a life and i try to not attack other audiophiles with my dogmas....It is not your case... Practical acoustic is an art based science not a science, like medecine is an art by the way...

@audio2design --

You don’t have to have a highly efficient speaker to overcome dynamic compression in normal usage.

Now, before you tell me what I don’t know and need to know, consider the following:

What system constellation as it pertains to minimum cone diameter, sensitivity rating and wattage would, according to you, be able to deliver sufficient SPL coverage for "normal usage" with a room size of, say, up 30 square meters (or, no more than ~3,000 cf. total volume) - as an active design with the whole none off-the-shelf trimmings, that is, so to stay on your home field? Room acoustics per your preference here.

Enough for a while with any further elaborations of all the exclusivities in regards to tailored driver design, impedance matched amps, measurement methods, analysis and DSP tools and other sheer engineering prowess. Let’s get some blunt, physical requirements in place as per the above.

As the article points out, there are methods of voice coil design, speaker design, material choices, etc. that can all mitigate these problems, hence probably why there are 100’s if not 1000+ speaker designers, but very few professional driver manufacturers, and why top speaker companies design their own drivers.

Would said mitigations make up for what bigger and more efficient drivers incorporating horn- or waveguide loading with compression drivers could do in regards to fairly uninhibited dynamics? What’s sufficient SPL-wise, even? How about headroom - lots of it; does that make of sonic difference to you, the ease that comes from using lots of radiation area and high efficiency?

One thing would be an acknowledgement of the above as a stand-alone factor; another whether it’s compatible with a commercial design meant for sale with all that entails and the size restrictions and other that typically follows here. It’s a convenient stance implicitly claiming what’s "sufficient" for normal usage, likely catering to a product development of one’s own within said limitations, when setting the bar higher in that regard could make a worthwhile difference to some - non-commercial it may be as a product range.

It is also a reason why active speakers will be necessary for the absolute in sound recreation.

Fundamentally, we agree on this.

High sensitivity speakers cost more to make and lets not forget that higher efficiency speakers with higher impedance cost even more to make but it all comes down to good quality design for any speaker to make them perform and sound good you will know when you find the right one for your ears because all sounds will just sound right to your ears.
