Prices are for one speaker. We list them that way because some people buy an odd number, like when a center channel is used for home theater. The plans include the crossover schematic. Kits include the completed crossover, ready to install. Box tuning is critical for bottom octave performance and really doesn't affect the midrange, except for bandwidth issues such as intermodulation distortion. In that sense, whatever you do to increase bass extension also increases IMD and, all things being equal, group delay as well.
