Speakers design: back My speakers will be made out of concrete. Now, before designing the speakers, one must, regardless of the material choice, decide on the type of enclosure to make. The most common options are: sealed, ported, and passive radiators.
Even though I wanted to design (and calculate) my own ported type of enclosure, I unfortunately need to stick to sealed one, as the chinese speakers I have ordered contain no information about their effective parameters. Since, soundwise, things can get worse after a wrong choice of port parameters, I go by the sealed type of enclosure
The only "calculations" that one must make in the speakers design is to make them as big as possible and, importantly, get rid of all possible resonances in the system, making the aspect ratio of the internal volume as irrational as possible
