AWSOME app. Gives me an idea of my port tuning and cabin gain so I can make my stuff bang correct the first time around. If you understand how it works you will love it.

I am new to speaker building and I knew I couldn’t build a quality speaker with out having software to make the various different calculations. I love the built in library with all the manufacturers specs. This apps makes it super easy to create a quality design.
