I’ve stumbled on a problem when I was designing a speaker. I use the winisd software for modelling the speaker. Once one has finished modelling, the program gives a box-volume(v) and port size. In my case the box volume was 50 liters and the port had a diameter of 7,6 cm and a length of 16.6 cm.
In my design the port will be inside the box. Correct me if I’m wrong, but that means that the internal volume of the box should be the volume given by winisd + the volume of said port that will be inside of the box, right? If so, should I also take the driver volume into account? If so, is there any easy trick to find out what volume your driver is?
In my case I’m planning on using 18mm mdf as base material. So the internal volume should be equal to 50L + (Pi*8cm^2(ie. outer diameter of port)* (16.6cm-1.8cm) )/1000(in order to go to liters) + driver volume
≈ 50L + 2.98L + driver volume = 52.98L + driver volume.
Lastly, once I had my volume I was planning on getting the box dimensions by taking the third root of the volume converted to cm. Is this a proper way of getting the box dimensions? I’m kinda newbie to this so if there are certain design rules for converting your enclosure volume to dimensions plz share :).
Thanks a lot for the help.
