Re: Re: Re: Re: Re: Re: Technical Discussion about Frequency Dependent Terminal Impedance
soongsc,
I meant this thread to be an discussion about the effects of terminal impedance on the speaker (power delivered) and how it affects the energy delivered to the driver. I'm trying to ignore driver effects/distortions for the time being. (In all reality, you cannot separate out everything, as reactances and loads are tranaformerd and referred back to the terminals through the driver and voice coil)
In any case, I was serious about a thread discussing the effects due to distortions in the cone, and cone resonances, etc. It appears that you are much more knowledgable in this area that I am. In that case, I am very interested in learning what you have to say! (I have to admit, I don't know a lot about speakers! (I do a lot of amplifier stuff, tho)
I often find that I learn more by throwing topic into the air, and letting more knowledgable people discuss it, while I sit in the back an absorb it all.

Discussions about amplifiers do not require to obey to the above rigorous rules, do they ?

My composition capabilities are often referred to as "Three Sentence Composition". But see Wireless World 1970 "The Design and Use of Moving-coil Loudspeaker Units" by E. J. Jordan. You don't see many articles as straightforward as this anymore these days.
