Some of the comments here are hugely ignorant as to what AI might be used for in speaker design, at least initially.
There's a whole dollop of bias, too.
In the first instance, AI wouldn't be told to "create the perfect speaker", and off you go.
It'd be told to create a speaker with less than x% distortion, FR within +/-x%, and told of the factors relating to reflections, etc. It'd also be told what techniques have been tried previously. It'd then be given a price profile.
It can work on numerous levels, but in this respect, in this context, it's just cutting out a whole lot of time and waste.
Whether it's speaker design or whatever, AI can just use past experience to figure out what's worked and what hasn't, and use that information to inform the likely outcomes of future designs using those techniques.
