Thundrapro CXA

Has anyone heard of the product "Thundrapro CXA"  The Company is / was Atlas/Soundolier located in St. Louis Missouri   This unit is a deep bass power amplifier crossover system.  I have exhausted every search posable on the web.  And this thing does not exist.  Problem is I acquired one.  And have nothing to show me what it does much less what input signal it requires.

Any suggestions / knowledge of / help, would be greatly appreciated.
