| Content | The K.12.2 powered 2-way loudspeaker operates from a 2000 watt power module. This module delivers ample burst and continuous power for the loudspeaker’s premium drivers. Dynamics processing was built to protect the drivers from damage and keep distortion from the performance. Low-noise fan cooling design of the module allows the enclosure to be used in quiet settings.
Operation is easy right out of the box with an extensive list of factory preset EQ contours including Live, Dance, Monitor, and more. For other applications you want quick access to, use savable/recallable Scenes feature. This can store information such as user EQ, Delay, and input configuration settings for you to cue up at your convenience.
Loudspeaker has two balanced combo XLR/F plus 1/4-inch TRS connectors with independent gain control. The first has selectable MIC/LINE level input, the second has selectable HI-Z/LINE level input. Both inputs connect directly to a pair of XLR/M throughput connectors, allowing signals to be daisy-chained to another audio device. Connect sources such as smart phones, computers, and MP3 players with the included 3.5 mm TRS input jack. Line-level output with mixed signal from all inputs is provided.
Coverage is extremely accurate and handles well in a variety of acoustic spaces with little or no equalization thanks to Directivity Matched Transition and Intrinsic Correction. Directivity Matched Transition ensures uniform response across the coverage area by matching the coverage angle of the woofer at the cross-over frequency with the horn pattern. Intrinsic Correction techniques work to create smooth power response.
Rugged ABS enclosure protects elements of the loudspeaker while giving it a professional and unobtrusive look. Use as either a main PA or floor monitor. Speaker also has ergonomic handles and heavy-duty grille with fabric lining, dual pole cups for 0 or 7.5 degree downward tilt, and integrated M10 fittings to accommodate suspended applications.

The ultra-compact SuperSub X (just a little bigger than a 12-1/2" cube) utilizes the same dual-plane, patented inertially-balanced driver array as the SuperSub XXL, but instead employs two horizontally-opposed 8" ultra-long-throw active drivers and two vertically-opposed 10-1/2" x 9-1/2" planar infrasonic radiators, driven by a 1400 watt Class D Digital amplifier.
GoldenEar's best subwoofer, the new SuperSub™ Series models are ultra-high-performance yet amazingly 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, the SuperSubs, GoldenEar's best subwoofer series, incorporates a unique, patented 360 degree dual-plane inertially-balanced driver and sub-bass radiator topology, combined with a very advanced electronics package. With two active drivers separated horizontally in space, as well as two passive radiators separated vertically, the driver-to-room coupling is distributed much more smoothly, for in-room bass performance that can’t typically be achieved with a single subwoofer.
The electronics packages that drive the SuperSubs' fully balanced array are a 1600 watt (XXL) and 1400 watt (X) Class D Digital amplifiers whose design is based on the technology originally developed for the GoldenEar Triton One tower. Features include: Discrete multi-band limiting, phase-perfect equalization, fully balanced and advanced reconstruction filters and a strong focus on keeping latency to an absolute minimum. Input facilities include a direct-coupled, unfiltered LFE input for home theater, or stereo Left/Right low-level inputs with low-pass for two-channel setups. Sonically, the result of all this technology is a 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.

The compact, 14" Tall Aon 3 Bookshelf Monitor incorporates a 7", High-Definition, Multi-Vaned Phase Plug (MVPP™), cast-basket Mid-Bass Driver, coupled to two 8" Inertially-balanced side-mounted Low-Frequency Radiators and the GoldenEar High-Velocity Folded Ribbon Tweeter (HVFR™).
The BRX, Aon 2 and 3 bookshelf speakers are exceptionally compact, ultra-high-performance speakers that were originally developed for use as nearfield monitors in professional mixing applications. The design goal was to produce modestly-sized shelf or stand-mountable bookshelf speakers that would achieve accurate high-definition sonic reproduction, with superb three-dimensional imaging, comparable to that achieved by GoldenEar’s award-winning Triton Towers. The new BRX was specifically developed incorporating technology developed for the Triton Reference in order to achieve reference level performance. Although they don’t have quite the awe-inspiring bass of the floor-standing Tritons, great care has been taken, and extensive technology has been incorporated, to ensure that the BRX and Aons can deliver a remarkably satisfying full range listening experience without the need for a separate subwoofer.
Both the BRX and Aon models incorporate GoldenEar-designed cast-basket bass/midrange drivers with technology derived from the midrange units developed for the Tritons. The BRX driver is actually almost exactly the same as the 6" driver used in the Triton Reference. In addition, they all use extraordinary and costly High Velocity Folded Ribbon (HVFR™) high frequency radiators. And the BRX uses the same tweeter developed for the Triton Reference. Lastly, each BRX and Aon model utilizes two side-mounted planar low-frequency radiators in an inertially balanced configuration in order to properly load the bass/midrange drivers for an open, box-less midrange, while also contributing to their’ remarkably extended bass for such small enclosures.
| The ML-55 has a 5.5″ mineral-filled polypropylene cone woofer, which combines the stiffness needed for accurate sound reproduction with the quick transient response that makes music come alive. |
The ForceField Subwoofers are unique in appearance and incomparable in its deep, rich bass ideal for music and movies. The ForceField 3 is extremely compact and affordable without compromising its ability to perform.
The ForceField Subwoofers’ unique and attractive cabinet shape, with its non-parallel cabinet walls (the top is narrower than the bottom when viewed from the front), helps the ForceField subs achieve extraordinarily deep and tuneful bass that is ideal for music and movies. Their cutting-edge amplifier design employs state-of-the-art DSP control for frequency shaping so the subwoofer produces accurate, consistent, and musical bass performance.
Many of today's subwoofers fall into either the ultra-compact high-output category or the (larger) high performance, extended response, high-output category. These two design types tend to offer different performance benefits, the ultra-compact having the ability to play extremely loud, but over a narrower bandwidth and the large subs having this high output plus more extended response.
GoldenEar's engineering team set out to accomplish the best of both worlds with the new ForceField subwoofers: small size, yet with the smooth & wide response of a larger sub. There's no sleight of hand, just great engineering - all ForceField subwoofers share the same technologies, here is a list of their features. Read through these and then take a good demo disc into your GoldenEar dealer's sound room and listen for yourself.
- Custom-designed high-output drivers with very large motor assemblies. These drivers handle massive power, have very long excursions, and have ultra-low distortion.
- Rigid cabinets with non-parallel sides to minimize standing waves and distortion. The drivers are front firing in all of our subwoofers for optimal performance. The cabinets' possess a unique and understated shape and style that matches well with any décor.
- The driver's response is enhanced with a carefully tuned, down-firing, quadratic-shaped passive radiator (no noisy ports on ForceField subs). The quadratic shape allows the radiators to use maximum surface area on the bottom of the cabinets and gets even greater output from the slot-loading that results from the subwoofers' interface with the floor (see next point).
- The soft, energy-absorbing feet provided with every ForceField sub serve a number of functions. First, they hold the subwoofer at the correct distance off the floor so the passive radiator slot-loads with it for significantly increased output at the lowest frequencies. Second, the soft feet keep the subwoofer from dancing around on the floor.
- ForceField subwoofer amplifiers are designed in-house by GoldenEar engineering, so each is the perfect amp to power its specific subwoofer model.
- In addition, the amps all have powerful DSP sections to optimize frequency response, minimize distortion and prevent damage from overdriving. These amplifiers are all low distortion and extraordinarily powerful (up to 1500 watts on the ForceField 5) for reproducing seriously high-output AND low bass.
- ForceField subs all have speaker-level inputs and outputs (with a high pass crossover on the outputs) as well as a direct LFE input, too.
- Non-parallel sides minimize standing waves and distortion. The shape allows the radiators to use maximum surface area on the bottom of the cabinets and gets even greater output from the slot-loading that results from the subwoofers' interface with the floor.
- Features 1000-watt digital amp, 8" high-power long-throw active driver, and 9-5/8"x 11-3/8" quadratic planar infrasonic radiator.
