The following is a press release issued by GoldenEar Technology.
November 15, 2016 | Stevenson, MD - GoldenEar’s new SuperSub™ line up is a very special group of ultra-high-performance compact subwoofers that incorporate many recently developed unique and advanced technologies and components. The goal was to create beautifully styled, finely finished, reasonably sized subwoofers, that could generate very low frequency pressure waves of extremely high amplitude, while delivering accurate and precise low frequency performance that is both highly impactful and extremely musical. In order to achieve this, we have incorporated a unique, patented, 360 degree dual-plane inertially-balanced driver and sub-bass radiator topology, combined with a very advanced electronics package. The first of these extraordinary new subwoofers to be released, the SuperSub XXL, shipped in November 2015, and has already received fantastic press and consumer response. In addition, it is the proud recipient of one of the industry’s highest honors, the 2016 International CES Innovations/Design and Engineering Award. We are now pleased to announce the second SuperSub, which is already being described as,” a true compact wonder”: the extraordinary new SuperSub X. In reality, the new, amazingly compact SuperSub X, was the original focus of this development program. It is, as was intended, the best ultra-compact powered subwoofer ever created, delivering extraordinary musicality along with earthshaking impact.
The attractive enclosure of the X is constructed of very thick, high density medite, which is beautifully finished in a luxurious high-gloss piano black lacquer. It is intricately and effectively braced in order to eliminate the possibility of resonances or the flexing of cabinet panels due to the tremendous internal pressure that is generated. There is a unique (patent pending) combination of two fully inertially-balanced 8" long-throw active drivers in the horizontal plane and two fully inertially-balanced 10-1/2" x 9-1/2" planar infrasonic radiators in the vertical plane. This force-cancelling inertial balancing preserves, conserves and focuses all the energy produced by the transducers in order to effectively move the air in the room (rather than the box), as well as enabling full recovery of the finest details, rather than allowing loss and blurring due to wasted box movement. In a way, it is as if the enclosure were a totally inert 500 lb. cabinet, but in some ways even better. Also, because there are two active drivers that are separated horizontally in space, as well as two passive radiators which are separated vertically, the driver-to-room coupling is distributed much more smoothly. The different driver locations couple to different room standing wave patterns, thus working better with and driving multiple room eigenmodes, almost as if you had two separate subwoofers.
The electronics package that drives the fully balanced driver and radiator arrays is unique and effective. There is a 1400 watt Class D Digital Amplifier, originally developed for the Triton One, that is controlled by a 56-bit DSP device with a 192kHz sample rate, which is in effect a mini-computer. This Programmable Logic State Machine has nearly instantaneous 278 ns update time to perfectly manage a myriad of functions including frequency response, soft clipping, DC offset control, output-stage saturation control, discrete multi-band limiting and phase-perfect equalization. The amplifier also utilizes many small, separate power supplies for each circuit section in order to provide isolation, so there is little opportunity for coupling through the power supplies. A fully balanced topology is used to minimize noise and distortion.
Finally, advanced reconstruction filters are utilized in order to maximize damping factor.
Sonically, the result is rock-solid bass response that is both exceptionally fast and tuneful for music, and extraordinarily deep and powerful, in order to effortlessly reproduce the most extreme movie sound effects. Also, of critical importance, is the fact that the electronics have been designed with a strong focus on keeping latency to an absolute minimum. Latency is basically time delay that exists in digital circuits. It has the effect of moving the subwoofer back from its physical position. This creates a misalignment with the rest of the system. We have measured many subwoofers that have relatively extreme levels of latency, which, in effect, moves the subwoofer back 15 or 20 feet. Two RCA inputs are provided for both LFE connection, as well as low-level connection from a stereo source. There is a precision level control as well as a phase perfect low-pass control to enable seamless integration into any system. GoldenEar has been awarded a US patent on its breakthrough Dual-Plane Inertially-Balanced technology. The SuperSub X is shipping now.
