Hello everyone, I'm trying to understand how simulation works in VituixCAD. I started with the measurements on the IEC panel provided by the manufacturer, I then rechecked the measurements with the Trace tool to integrate the low-frequency range and the diffraction of the panel using the Merger and Diffraction tools in Vituix.
After that, I created the active crossover filter and arrived at the result I am posting. The goal is to create a project as mature as possible with the most accurate simulation, then move on to the actual construction, supported by measurements that will be verified and compared with those from the simulation.
I’m attaching some images to show you the preliminary version of the simulation.
One thing that’s not clear to me is how to use the Diffraction tool with multiple measurements extracted from the datasheet. Let me explain better: if I "capture" the response at 0°, 30°, and 60° with Trace, how can I use them all with the Diffraction tool, considering that even just using the measurement at 0° it calculates the directivity from 0 to 180°?
A few words about the project... the enclosure will be a stand-mount speaker, slightly over 40cm tall, with a depth of about 35cm and a width of 20cm. It will have a tweeter and a midwoofer mounted on the baffle and two subwoofers on the two side panels. For the tweeter, I’ve chosen the Scanspeak D3004/6600 since I already own it (I’d like to evaluate it with and without a waveguide in the further stages of the project), the midwoofer is the SB Acoustics SB15NBAC30-8, and for the two subwoofers, I’m using the Dayton Audio DCS205-4 8-inch drivers.
I hope I can use this project to understand how far one can push in simulating a rather complex speaker, and maybe inspire some of you to offer me some valuable advice.
Grazie
Stefano
