GoldenEar ForceField 40


10″ compact powered subwoofer with digital signal processing

Agile, powerful bass from a compact sub

GoldenEar has updated their space-efficient ForceField subs with upgraded electronics inspired by their impressive SuperSub lineup for cleaner, extended low frequencies. The ForceField 40 packs a heavy punch while revealing subtle low-frequency details, serving up bass that’s perfect for dedicated music listening and movie night in equal measure.

The sub’s long-throw 10″ woofer has a computer-optimized, ultra-stiff fiber cone and a massive high-gauss magnet assembly. It’s driven by a tremendously powerful 1,200-watt RMS amplifier, which uses DSP (digital signal processing) to minimize distortion in real time. And a down-firing 11″ x 13″ quadratic planar radiator extends low frequencies all the way down below the range of human hearing.

High-quality construction

GoldenEar’s engineers have an eye for detail, and it adds up in the ForceField 40’s construction. Thick cabinet walls and a curved, extended top panel keep resonance and distortion down to a minimum. The perforated metal grille is acoustically transparent, and soft, vibration-absorbing feet provide noise isolation. The feet also maintain just the right distance between the floor and the passive radiator to maximize low-frequency output.

Simple setup and control

The ForceField 40 has a dedicated LFE input that hooks up to the subwoofer output of your home theater receiver. That input jack also serves as one channel of the sub’s stereo line-level input, which you can use when connecting to integrated amps and stereo receivers. Using the built-in variable low-pass crossover, you have control over what frequencies the sub plays when using the left/right line-level connections.

Who is GoldenEar?

Since their founding in 2010, GoldenEar has racked up rave reviews across the audio industry for their high-tech speaker lineup and cutting-edge design philosophy. The company’s goal is to create speakers that sound better than comparable models costing three, four, or even five times more. Their signature sound includes pinpoint stereo imaging, a spacious three-dimensional soundstage, and ultra-low distortion. Each of GoldenEar’s custom-designed drivers, passive radiators, and carefully tuned cabinets help create an ultra-immersive listening experience with your favorite albums and movie soundtracks.
