Patent Review: Vertically and Horizontally Balanced Subwoofer

The patent reviewed here was granted to inventors Robert G. Johnston (Amprior Ontario, CA), and Sanford M.Gross (Owings Mills, MD), respectively the head of engineering of GoldenEar Technology, and one of its co-founders. The patent describes a subwoofer with two drivers on each side plus one passive radiator facing up and one passive radiator facing down. The passive radiator facing down effectively couples acoustic energy at very low frequencies into the floor.

GoldenEar Technology, the manufacturer of home audio loudspeakers, and The Quest Group, best known as the owner of the AudioQuest brand of cables, Niagara power products, and DragonFly DACs, have announced that GoldenEar has become part of The Quest Group, a California corporation wholly owned by AudioQuest founder and CEO Bill Low. In a letter sent to GoldenEar dealers and distributors, Sandy Gross justifies the decision based on what The Quest Group's resources and capabilities can do for the company.
