Frequency Response

Unlike speakers, a subwoofer does not need to have a frequency response at the low end of a spectrum. According to our audio engineers, the bass response ranges from 29 Hz-120 Hz, but it isn’t exceptional. Bass notes below 29, he won’t be in high demand. However, if you have low-frequency notes above this subwoofer’s capabilities, then they won’t be heard.

It has a simply perfect sound. The sound is consistent even at high volumes. It also retains its punchiness, which makes it even more enjoyable.

Notes of High and Low Frequency

The Klipsch R120SW subwoofer offers a decent frequency range but is not the best. It is impressive, I don’t doubt, but it could be a little better. Rock music is excellent, and high notes are delicate. But it was the low notes that needed some improvement.

Notes below 29Hz are a little problematic. This is the lowest possible frequency input/output. While not all sounds are below this threshold, those that are can be played are challenging to understand. You might be able to pick notes down to 27 Hz with a powerful receiver. But that is not usually the case.

It is not an issue; the frequency range is quite good. However, lower notes could be improved. Although you can improve the performance of lower notes with a loud receiver like mine, it is still an area that needs improvement. Overall, however, everything is great, especially the bass.


This unit can handle any music, including pop, rock, new wave metal, jazz, blues, or classical music. The sound is balanced, and the unit produces excellent output in the 45-60 Hz range that most songs love. As we have seen, it can go much further than this range.

Its focus on bass is the best part. The Klipsch R120SW will bring life to your jam sessions and parties.

All-in-one Entertainment Sound Unit

It shines brightest when it comes to music. And why not? With such incredible detail afforded by bass, it is an all-in-one sound master. Do you want to spice up your movie viewing experience? Do you want to spice up your movie experience? This subwoofer is a great option.
