Saw one of these for sale and ran the Eminence parameters. It truly is a bass guitar speaker, it doesn't fit many other uses.

It works best in a smaller box than earlier suggested. I came up with a 1.3 cu ft box, with a 1.8" diameter port 1" long (the thickness of a hole in good baffle).

With that, the power handling maxes out about 40W "maximum electrical power" at 60Hz or 40W pushing it over XMax below 30Hz (but bass guitarists might like making distortion...). In a ported box, this needs a subsonic filter, or an amp or instrument which doesn't make subsonics.

Makes 113dB at 100Hz with that 40 watts though... and +/- 3dB 60Hz-1kHz
