Loudspeaker

Objectives

The following information WAS provided for training purposes. But now it will be used as consumer exposure purposes. To expose the regular consumer about the level of audio loudspeaker manufacture technology / limitations and hence reality.

Another objective is to let other engineers, more importantly bosses know that the public starts to aware of these matters and they had better start producing good products and not let die. Well, if this website can educate enough consumers???

It is hoped that these information will be useful to the readers so that they would think carefully before answering any questions, for accuracy and professionalism purposes.

If the answer cannot be backed by documented proof, please refrain from using it, unless it is extremely logical.

Professionalism

Whatever not said cannot be assumed i.e. don’t put your own thoughts/idea into the explanation.

When there is the slightest confusion or question, please stop me and ask. Oh! we are not with each other now, errrrrrrrrrrr so read again, or errrrrrrrrrrrrrr email me.
