DeVore Fidelity is a Brooklyn, New York based audiophile maker of some very nice looking floorstanding loudspeakers including the Gibbon and the Silverback. While named after primates, the speakers don't look very monkey-like.
Founded in 2000 by John DeVore, DeVore Fidelity designs and builds their own speakers.
The DeVore Fidelity Gibbon Super 8 has a claimed frequency response of 36 Hz to 40 kHz from it's two-way design. The DeVore Fidelity Silverback has a claimed frequency response of 21 Hz to 40 kHz.
