This best Klipsch subwoofer is similar to its predecessor, the R-120SW. However, it has an improved driver and woofer, which allows it to produce an even cleaner base with a frequency response as low as 28 Hz. 

The size is also slightly different, as this one is a little bit bigger and heavier. The construction is based on MDF with a vinyl finish that’s scratch-resistant. So in terms of its design, it’s similar to other Reference series subs. Still, the new construction is supposed to reduce cabinet vibrations. 

The front-firing driver allows placement flexibility. It also has a front-mounted LED power indicator that tells whether the subwoofer is on or off. However, the inputs and controls are on the back. 

Its all-digital amplifier has a 0/180 phase and auto power-on function. 

Pros

  • Cleaner bass
  • Refined design
  • Easy tuning
  • No degradation or distortion

Cons

  • Heavy
