Pros and cons

According to our subwoofer expert
  • The low frequencies stand out thanks to the light and sturdy material of the woofer.
  • With the low pass and gain buttons, you can adjust the sound reproduction to the acoustics of your room.
  • You don't need an amplifier when you use this speaker, because it's active.
  • A subwoofer cable isn't included.

Description

You can enjoy music as the artist intended with the Klipsch R-121SW. This 12-inch subwoofer has a frequency range between 28 and 120Hz, so the bass sounds deeper and more intense. It's made of lightweight materials like spun-copper, so it's lighter than subwoofers from other brands. You can adjust the sound to the acoustics of your room with the low pass and gain buttons. The subwoofer is active, so you don't need an amplifier.

good price/quality

  • Easy connection
  • Beautiful design
  • Finish

Just got my hands on it, but very satisfied. Very nice warm sound. I have it connected to a Denon avr-x2300 and it plays without interference or noise. Now that I have this in my possession, I might have taken a closer look at the slightly larger version, a small tip!
