Product Registration

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.

Sliding Terminal Cover

Detachable sliding terminal cover offers a sleek design and easier installation.

One-side Connection

All terminals and connections are on one side for easier installation and a cleaner look.
