Loudspeaker Frequency Allocator is a useful tool that allows you to change the frequency output for the ASIO compatible sound cards. The interface is easy to use and allows you to view the visual representation of the output and to change the parameters.

It supports presets and is able to save your settings to a file in order to load it later. Each DSP crossover leg can be fine tuned from 6dB/oct to 42dB/oct in order to get the desired result.
