And even within the utilisation of composites, there are multiple cores and each behaves differently. Some use balsa, others use airex and in my case, I use a nomex honeycomb. To my knowledge, I am the only company that uses a nomex honeycomb core and if you recall, I even sent you a white paper on the benefits of this, explicitly around sound damping.
No I dont believe this. This is just splitting hairs. Brick would do the job. Its cheap and readily available. There is no point in trying other materials. The point you seem to miss is that a speaker box is WRONG. it doesnt matter what you make it out of if its WRONG.
Why do you think open baffle speakers exist? Because its an extreme attempt to solve the problem of having a box. You have an obsession with box material and its completely misguided.
Have you read the paper yourself?
this post isn't about my speakers, it's about Vivid .
Yes but vivid is a good example of a speaker that tries to solve most of the main problems with box speakers and for that reason its justified in mentioning bad speakers that dont bother to deal with all the problems. A speaker box made of solid 5 inch thick diamond slabs would still sound horrific if for example the crossovers were badly done. That is only one example.
You only ever speak about cabinet material which is misleading.
I bet your speakers arent even custom tuned either. They are just mass produced. Which is another problem.
