About this app
Woofer Box Calculator PRO will help you design enclosure (box) for your bass car audio speaker (sub woofer). It was developed by 2012 and 2013 European champion in dB Drag Racing and was designed to be easy and transparent. It is better than other software because it also considers approximate cabin gain, power compression and port compression. Because of that, it can also predict final SPL in your car. Furthermore, it knows how to handle total (gross) box volume instead of net box volume. It can also calculate vented (ported) enclosures in the opposite way (e.g. it can calculate vent size or total box size for desired vent). It can even calculate optimal box for your car and equipment, for burping or for music, depending on priority (SPL to SQ). Projects can easily be saved and loaded. Boxes, Drivers and Vehicles can also be saved and loaded separately. Units an constraints can be changed under settings. This is the PRO version with without advertisement and all features unlocked!
