The Electric Lightning's tone is straightforward and powerful with fat lows, throaty mids and crisp, bright highs. It is a true "in your face" Rock n' Roll speaker that can handle the heaviest of playing styles and is designed for loud applications.

I play in an eclectic punk band and I use two Electric Lightning with a Marshall 100 tube amp and it sounds killer most of the sound men think I am too loud but the rest of the band and the audience loves it! Thanks Jensen!
