Wilson Audio Thor's HammerThor is popularly known as the Norse god of thunder. He is often depicted carrying a short-handled hammer named Mjollnir, a symbol of his awesome power. Thunder is fitting to associate with Wilson Audio's new state-of-the-art subwoofer. Truth be told, Wilson’s large subwoofer may put to shame the notion of thunder, which primarily occupies the frequency spectrum from 20-120 hertz. Thor's Hammer (the subwoofer) is capable of reproducing at full volume the lowest pipe organ note at 16 Hz.
