Golden Ear ForceField 4
Ultra-Compact Extended-Response Subwoofer
The compact 10 inch subwoofer ForceField 4 incorporates the same 1200-watt digital amp developed for the Triton Two. It drives a front-mounted high-power ultra-long-throw 10” sub-bass driver coupled to a downward-firing 11”x 13-7/8” quadratic planar infrasonic radiator.
GoldenEar’s™ award-winning ForceField subwoofers have been engineered from the ground up to combine subtle musical detail with earth-shaking high-impact power; all in attractive, compact enclosures which blend well into any environment. GoldenEar’s engineering team has the benefit of over 20 years experience designing some of the world’s best sounding, most highly reviewed and best-selling powered subwoofers. Paramount in their design goals was the importance of not sacrificing sound quality in order to achieve unrealistic size goals.
But just as key was the importance of compact size that did not make the subwoofers any larger than necessary in order to achieve uncompromising, state-of-the-art, sonic performance. You will instantly see and hear how well these seemingly conflicting goals were brilliantly both achieved with the combination of creative thinking and cutting-edge engineering prowess.
Of course, to achieve a tour de force like the ForceFields, the basic concept is absolutely key. The ForceFields all combine high-power forward-radiating ultra-long-throw sub-bass drivers coupled to downward-firing quadratic planar infrasonic radiators. This brings together the superior transient response and detail of moderately sized active drivers with the subsonic capability and extraordinary room-filling coupling of large diaphragm radiators. In fact the radiators, in combination with the slot-loading to the floor, approximate the near perfect impedance match to the air of a well-tuned transmission line. This combination is also very flexible in terms of room-placement requirements.
Next, the engineering team spent countless hours developing a unique high-power (FF 4–1200 Watts & FF 3–1000 Watts) DSP controlled class D digital amplifier. This sophisticated amp has a Programmable Logic Device (PLD) based state machine with a nearly instantaneous 278 nano-second update time, to perfectly manage a myriad of functions including: soft-clipping, DC offset control, output-stage anti-saturation protection and discrete multi-band limiting. The DSP control also allows for very precise equalization. In addition, intrinsic THD is extremely low, so very little negative feedback is required, thus ensuring optimum transient performance.
Finally, a unique cabinet shape was chosen, both for its undeniable aesthetic appeal, as well as its performance enhancing attributes. The non-parallel cabinet walls dramatically cut down and help control internal reflections, as well as stiffen the cabinet structure itself. The end result is stunning impact, superbly musical bass articulation and breathtaking infrasonic capabilities that can powerfully pressurize a room in a way that leaves listeners breathless. The unique achievement of the ForceFields means they can bring the power of T Rex into your living room, as well as the musical subtlety of YoYo Ma or Sting.
