Speaker Analysis for Armchair Critics


Hello everyone,
There’s a very important discipline called "Speaker Analysis" or "Speaker Testing" which though complicated, is brilliantly illustrated in this breakdown of the B&W 685.

Speaker analysis is to measure each of the components both separately and as they come together in a complete system. It is a part of creating a new loudspeaker, but it can also be used to analyze an existing speaker, to understand it and perhaps to make it better.  I prefer the term Analysis because it better reflects that the goal is not merely quality assurance, but to build a complete electro acoustical understanding of the system as a whole so changes can be considered, and their final results predicted.


This particular article does just that, and comes up with a couple of suggestions for re-working the crossover to end up with hopefully a better end result. At the very least, it is a significantly different speaker at the end, and achieves a far greater level of change than cables can.


I share this with all of you just as an example of the work that goes into making a loudspeaker from parts, and the tools, and how much of what we hear has to do with choices made in the crossover.


Best,

Erik

Dude, for real???

You have argued that no designer knows how to build a speaker, now you are saying that the designers know best?

And yeah, thats classic Duke!
"So what makes a DIY speaker made by a novice who has no degree, no knowledge and no experience, less good than a speaker made by a true speaker designer if in the end its just a matter of a particular signature and theres no right or wrong signature?"

What does that have to do with anything?

Like everything else you state, absolutely nothing.

Your statement said quite clearly that "There is no signature sound its a myth"

The comment had noting to do with bad or good, it had to do with a signature...

Genius

"There is no signature sound its a myth."

Really? 

How do you figure???

Harbeth, Tannoy, Klipsch, Ohm, B&W..

They don't have a signature?

If its not by design, then your rationale would be that the designers keep making the same mistakes over and over...

special, very special...


Once again, Kenjit fails to answer any question directly.

Politician perhaps???

"You have opened a can of worms here you dont know what youre getting yourself into.

Speaker design is a mishmash of ideas with a bit of hogwash for good measure."

Direct question:

What do the above two statements mean - specifically? No round about silliness with diversionary ramblings switching the subject.

Regarding the eagle:

...we walked with frail apprehension, our eyes daring not look up. We knew the force, power and majesty of everything was there, looking down at us. We who were so much less then it. All we could, was stop, close our eyes and listen in fear as all was about to be revealed with crystalline clarity...
And how about that "There is no sound signature its a myth" statement.

Are you going to back up that rather "bold" statement?
