Features

• Output Coil with Magnetic Shield
  Prevents magnetic flux from radiating from the subwoofer's coil, resulting in reduced noise and enhanced sound quality.
• High Quality Capacitors
  PMLCAP's (Polymer Multi-Layer Capacitors) are utilized in the LC filter circuits to decrease distortion, ensuring clear detail for a truer to life sound.
• Infrasonic Filter (ISF)
  When the Infrasonic Filter Switch is turned on, the amplifier cuts off the low frequencies below 25Hz, which makes the amplifier’s power supply and output devices more efficient, providing clear bass output.
• One-side Connection
  All terminals and connections are on one side for easier installation and a cleaner look.
• Speaker Level Input Harness
  Speaker Level Input Harness is included to connect to speaker wires from factory installed receivers.
• Wired Level Control Included
  The wired remote level control allows you to easily adjust the subwoofer volume.
