This crossover was pulled out of an old PA speaker that had a Horn and a 15" woofer.  Has the JH Sessions & Son engraving on the terminal plate, but the speaker had a big WRIGHT badge on the front.  Not sure the capabilities, all I can tell you is that it works and the woofer was an 8ohm 400 watt woofer.  Crossover is in great working condition, input terminal has a bit of rust cover on the backside as pictured. Please let me know if you have any questions. Thanks for looking!
