Use BassBox to optimize your speaker system’s low‑frequency response – it's the easy way to create great speakers and crossovers.

Harris Technologies produces BassBox, a speaker enclosure design program that determines optimum volumes and tunings for woofers. Before you buy a new driver or cut wood to construct a loudspeaker system, BassBox will model system performance based on a woofer’s parameters and the size and configuration of the enclosure itself. X‑Over Pro helps users design their passive crossover networks, find it here at Parts Express.
