GoldenEar Awarded Patent for its SuperSub X Series of Subwoofers

The Md.-based audio company was given a patent (U.S. 9,462,391 B2) for the design of its dual-plane inertially balanced SuperSub line of products.


The consumer audio market and especially the loudspeaker category are super competitive industries. Separating itself from its competitors in the speaker category is the Stevenson, Md.-based manufacturer GoldenEar Technology, which has announced that it was awarded a patent (9,462,391 B2) for the design of its Dual- Plane Inertially Balanced Technology that is utilized in its SuperSub line of subwoofers.  

GoldenEar explains that its Dual-Plane Inertially Balanced Technology preserves and focuses the energy from the subs' transducers to more effectively move air within a room rather than vibrate the subs' cabinets.

The subs utilize four radiating surfaces that are separated in space to help the subs driver-to-room coupling and to ensure the subs' response is more evenly distributed within a room. 

Featuring enclosures that are engineered to be inert, GoldenEar says the cabinets are so stable that users could stand nickels on their sides while the subs are at full volumes and the nickels won't fall over. 

The SuperSub X incorporates two long-throw 8-inch drivers, along with a pair of 10.5-inch x 9.5-inch quadratic planar infrasonic radiators driven by a 1,400-watt ForceField Digital Amplifier and 56-bit DSP device. 

GoldenEar says the SuperSub X provides a precision level control, a 12dB/octave low-pass control, two RCA inputs and a switch to select the direct-coupled, unfiltered LFE input. The frequency response of the sub is rated as 12Hz to 200Hz. 

The larger SuperSub XXL utilizes a pair 12-inch woofers, as well as a pair of 15-inch x 13-inch planar infrasonic radiators that are powered by a 1,600-watt Class D digital amplifier.
