Agile, powerful bass from a compact sub

GoldenEar's engineering team set out to accomplish the best of both worlds with the ForceField subwoofers: small size, yet with the smooth and wide response of a larger sub. There’s no sleight of hand, just great engineering. All ForceField subwoofers share the same technologies:
  • Custom-designed high-output drivers that can handle massive power while maintaining ultra-low distortion
  • High-quality construction featuring rigid cabinets to minimize distortion and soft, vibration-absorbing feet that provide noise isolation
  • Enhanced driver response with a carefully tuned, down-firing, quadratic-shaped passive radiator (no noisy ports on ForceField subs)
  • In-house subwoofer technology designed 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 for reproducing seriously high-output AND low bass.

Compared to previous models, the new ForceField 30 and ForceField 40 subs boast several significant sonic and cosmetic refinements, including: a compact, elegant cabinet with curved top panel to further minimize resonances, a perforated metal grille for improved transparency and airflow, an upgraded electronics platform with Analog Devices DSP, and a gorgeous Satin-Black finish.
