Subwoofer HQsing SW120

The HQsing SW120 combines deep bass performance with a distinctive wood cabinet and vintage-inspired design, making it an ideal addition to premium home audio and karaoke spaces.

Its 12-inch woofer reaches down to 24Hz, delivering deep, rich low frequencies that add greater depth and impact to music, movies, and karaoke. Powered by a built-in Class D amplifier, the SW120 provides 300W RMS and up to 600W peak power for clean and controlled bass reproduction.

The natural wood construction gives the SW120 a warmer, more refined appearance than conventional black subwoofers, allowing it to complement classic, vintage, and premium home interiors. An adjustable 40Hz–200Hz crossover and 0° / 180° phase control make it easy to blend the subwoofer smoothly with the main speaker system.

Setup

1. Place the SW120 on the floor near your main speakers, and keep objects from blocking the speaker face.
2. Power off all equipment and connect the sub output of your amplifier or digital processor to the SW120's input.
3. Plug in the SW120, turn on the amplifier first, then turn on the subwoofer.

Tuning

1. Set the SW120 volume low, then raise it gradually until the bass blends with the main speakers.
2. Set the crossover within 40Hz–200Hz: the smaller your main speakers, the higher the crossover point.
3. Try the phase switch at 0° and 180°, and choose the setting that gives tighter, clearer bass at your seat.

Care

• Wipe the wood cabinet with a soft, dry cloth; don't use harsh cleaning chemicals.
• Place the speaker in a dry spot away from direct sunlight and heat sources to keep the wood surface looking beautiful.
• Turn off and unplug when not in use for long periods.
