Meet the professional bass speaker (woofer) box calculator, designed for competitors and advanced bass box enthusiasts. It was developed by 2012 and 2013 European champion in dB Drag Racing.
It is the first box calculator that also considers cabin gain, power compression, port compression and other non-linearity, that changes the real world results completely. Because of that, it can also predict final SPL (dB) in your car.
It is especially handy for designing because it knows how to handle total enclosure volume (speaker and bass reflex port volume included) in addition to net enclosure volume. It can also calculate bass reflex (ported) enclosures in the opposite way, e.g. it can calculate bass reflex port dimensions or total enclosure volume for desired port, given a tuning frequency.
Design projects can easily be saved and loaded. Enclosures, speakers and Vehicles can also be saved and loaded separately. Units an constraints can be changed under settings.
Another unique capability is that it can calculate the optimal speaker box volume and bass reflex port dimensions based on your priority (SPL/SQ), volume available for the box, amplifier, speaker and vehicle.
