Add a new ressource to Speaker ou Array tool : (but unfortunaltely not the real perfect geometry...) 1- In VWX, go to Preferences/User folders/choose Reveal in finder Leave the window open and close VWX 2- In the open window, go to 2020/Librairies/Defaults/AudioTools 3- In this window, locate the XML file. If the file does not exist, ignore this step. If it exists, delete the file. Leave this window open, we'll come back to it. 4- Go to the application folder (in Applications on Mac, and Program Files on Windows) 5- Go to Libraries/Objects -Ent Audio/ 6- In this folder, choose the items you want to add to the Speaker tools (speakers and bumpers only), copy them in the same folder above: climb back to 2020/Librairies/Defaults/AudioTools/Speakers (AND-OR /Bumpers) 7- Open VWX, go to the Resource Manager, click on the wheel and choose "Refresh Libraries". 8- In VWX open a new document. Go to menu File/Documents & Settings/Units and choose Millimeters (necessary one-time step that needs to be done only once in order for VWX to add the imported elements at the right scale in the database) 9- Go to the Speaker Tool, and place a "generic" speaker in the drawing. 10- Select the speaker, then in Object Info palette choose Type, then Import. HERE THE STEP OF THE CHOICES: repeat this Import with each speaker you wish to import. They will now appear in the ressources of the tools. DONE ! Then, for line arrays, a similar operation is to be performed to add the manufacturer's bumpers: 11- Choose the Array tool. Add a generic bumper. Click Ok. Select the generic bumper, go to Object Info, then configure Array, and finally here the "import" button is available in the Type of bumpers. Choose the desired bumpers, one by one. 12- Add each bumper one by one, they will now appear in you ressources. DONE ! https://www.youtube.com/watch?v=JBdfWlmO6f8&ab_channel=Vectorworks

Edited the post, adding an advice to backup the xml file first before. (Most people only need only to perform this process after a fresh installation..)

So, you advise to not suppress the xml file. Ok. I have only transcribed the process described in this video from the official source :
