New GoldenEar Technology Dual-Plane Inertially-Balanced SuperSub™ XXL Subwoofer to Ship in November
(September 1, 2015 – Stevenson, MD) GoldenEar’s new SuperSub™ line up is a very special group of ultra-high-performance compact subwoofers which 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, patent-pending, 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 will ship in November.
The attractive enclosure of the XXL is constructed of very thick, high density medite , which is beautifully finished in 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. There is a unique (patent pending) combination of two fully inertially-balanced 12” long-throw active drivers in the horizontal plane and two fully inertially-balanced 12 ¾”x14 ½” planar infrasonic radiators in the vertical plane. This force-cancelling inertial balancing preserves and focuses all the energy produced by the transducers in order to effectively move the air in the room, 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 which 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 as the different driver locations couple to different room standing wave patterns, and work better with the room eigenmodes.
The electronics package that drives the fully balanced driver and radiator arrays is unique and effective. There is a 1600 watt Class D Digital Amplifier, originally developed for the Triton One, that is controlled by a 56 bit DSP device with a 192 kHz sample rate. 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 minimizing 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. The 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. U.S. Retail Price is $1999. ea
