Looks a 70V line transforner used in commercial speakers. IMO

This discussion is super interesting, but well beyond my ability to comprehend the technical side, would someone be able to purchase the jumpers and attach between the crossover and the binding post inside the speaker? If you purchase from the manufacturer no harm done.

The patent Maty posted is a not HARP. On a side note, Rochelle Salt and Tourmaline power are effective in absorbing RF noise IMO.
