Product Overview

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 Infrasonic Filter Switch is turned on,the amplifier cuts off the low frequencies below 25Hz, which effects to make the amplifier’s power supply and output devices more efficient with clear bass sound.


Conformal Coating

Improved moisture resistance of the circuit boards to prevent corrosion.


Protective Caps and Cover

All control holes,RCA, wired remote and Speaker Level input terminals are coverd with caps and plastic covers to avoid from moisture and dust.


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.
