Jensen Loudspeakers 12'' Tornado Stealth 100 Watt Neodymium Speaker - 8 Ohm 12'' Tornado Stealth 100 Watt Neodymium Speaker - 8 Ohm

The Tornado Stealth 100 is the original Tornado 12, the first of the new generation of Neodymium speakers in the Jensen offering with an added stylish bell cover over the magnet. Possibly the most versatile Jensen speaker ever, it has clear, almost HD top end, well-balanced midrange and powerful bass end. It lends itself to a wide range of musical genres, with a smooth, never aggressive personality, from fast solo runs, to complex chordal harmonies, to soulful lead tones.
