Purchased this app before it went free about a year ago and have used it to build three different enclosures. All sounded great and got down just like I wanted them to. Good folks this is how honest they are. Since I paid $1.99 for the app before it went free they upgraded my plan to pro user unlocking tons of perks because they are solid folks. Y’all gotta try it out

I have been looking for a comprehensive app for calculating the internal space required for a subwoofer based on a subwoofers parameters. I was disappointed to see that this app had no such thing. Hey Developer. How do I go about configuring what size a box should be when I don’t even know what the woofer needs? Take the simple, square box for instance. You ask for dimensions, bracing and woofer displacement but then you also ask for Fs, Vas and Qtc? What?.... The TSP is supposed to help me figure out the needed internal volume of an enclosure and it’s resonant frequency. How can I even start to “design” a box and start cutting when I don’t even know where to start!! Not everyone is a professional builder. This app makes that assumption.

Absolutely amazing app for designing and proof of concepting subwoofer enclosures with lots of extra features. I use this app all the time when helping people out online with designing boxes to fit in a given area. Would like to see updated with 4th and 6th order variations. Like using multiple chambers and it calculates the port from one chambers to the next and automatically remover that available area out of the next chamber.
