These calculations are available online, but it is nice to have an app ready to go. I like it. Additional features for more calculations would be fun in the future and but overall nice and clean and worth the $2 if you just want to get to the point, and skip the ads.

I tried to the frequency suppose 3,500 - 5,000. I can't type more than 3500. The dash icon/ symbol on the keypad is not in function . I already purchased this online, but it is not working properly. It would be great if they could fix it as soon as possible. Thanks Parmeshwar

textbook filters. poor way to design a crossover. this app does not account for the most critical aspects such as freq response, impedance (not resistance), baffle effects, phase, and acoustic offsets.
