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.
Gauge-style terminals lock wire
into position with set screw for secure installation.
One-side Connection
All terminals and connections are on one side foreasier installation and a cleaner look.
