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

Past that, it also helps to explain how a brand can develop their signature sound.
There is no signature sound its a myth.

Really love being called a liar without evidence.

Nice article which shows to fix the root cause.  Sometimes we only fix the symptoms.  I guess you have to cut the head of the snake to get the problem fixed.  
my signature is flat to the last band on the eleven band analog bass EQ with a Q of .72, unless I am listening to Steely Dan: Two Against Nature, then i tweak it back a whisker....

seriously Eric..keep doing your thing, learning, building speakers, etc....” Nolite te Bastardes Carrborund !” but also, don’t feed them....
