Impressive Components for a Perfect Bass Speaker
Due to the high-quality transistor technology, the approved design of these subwoofer active modules allows for an impressively warm sound of the self-built subwoofer system. The features and workmanship of the modules perfectly meet all requirements. SAM-1 and SAM-2 feature great dynamic reserves.

Active subwoofer module, 120 WMAX, 65 WRMS

  • Powerful active module of highest operating reliability
  • Suitable for subwoofers (12 dB slope) and full range speaker systems (jumper configuration)
  • Continuously adjustable phase control
  • Ground lift switch of the professional technology against hum interference
  • 24 dB subsonic filter
  • Automatic switch-on
  • Extensive protective circuits against short circuit, overheating and DC voltage overload

With the usual modern music material and a crossover frequency below 100Hz, the power of the SAM-1 for the bass range corresponds to a total amplifier power for the full frequency range of several hundred watts.
