GoldenEar has updated their space-efficient ForceField subs with upgraded electronics inspired by their impressive SuperSub lineup for cleaner, extended low frequencies. The ForceField 30 packs a serious punch while revealing subtle low-frequency details, delivering bass that’s perfect for dedicated music listening and movie night in equal measure.
The sub’s long-throw 8″ woofer has a computer-optimized, ultra-stiff fibre cone and a massive high-gauss magnet assembly. It’s driven by a tremendously powerful 500-watt RMS amplifier, which uses DSP (digital signal processing) to minimize distortion in real time. And a down-firing 9″ x 11″ 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 30’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 30 has a dedicated LFE input that hooks up to the subwoofer output of your home theatre 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.
Product highlights:
- built-in 500-watt RMS Class D amplifier
- DSP (digital signal processing) monitors the signal in real time for clean, precise bass
- front-firing 8″ long-throw woofer
- 9″ x 11″ quadratic planar down-firing passive radiator
- bass reflex (passive radiator) enclosure
- thick cabinet walls and curved top panel minimize resonance
- acoustically transparent perforated metal grille
- frequency response: 18-250 Hz
Connections and controls:
- left/right line-level inputs
- left input doubles as a LFE (mono-RCA) connection for use with a home theater receiver’s sub output
- variable low-pass filter: 40-150 Hz
- auto on/off
