Klipsch R-120SW – the world of high-quality sound!

Klipsch R-120SW review & specs

Progress does not stand still. And increasingly, in our homes, instead of TV, there are home theaters that allow you to watch programs and films of the highest quality in a pleasant home environment. We know that a subwoofer that reproduces sound effects, such as peals of thunder during a thunderstorm, explosions – low-frequency sounds, is included in the package of any home theater.

It is the low-frequencies of the soundtrack that add volume, create the feeling of music, add emotion to the reproduction of the rest spectrum of sound radiation. I hаd thе оppоrtunіty tо test one of the subwoofers Klipsch and I would like to do a Klipsch R-120SW review. Consider the R-120SW specs.

This model has a very attractive and, at the same time, minimalistic design. The device is presented in black color and is made of high-quality material. The main feature of the Klipsch R-120SW is the horn emitters that provide the unmatched precision of sound reproduction in the home theater and stereo systems.

Open fasteners, corner feet, and magnetic grilles give the speakers a modern look. The reinforced MDF design reduces body vibration for less audible coloration and improved sonic accuracy. The rear of the Tractrix ports will now bass more, improving airflow while reducing turbulence and distortion. Of the external changes, it is worth noting the angled legs, magnetically mounted full-length grills of the front panel and scratch-resistant vinyl trim. Woofers remained traditional copper color.


Active 12-inch subwoofer Hi-Fi class. The total output power is 200 / 400 W, and the frequency range is equal to – 29-120 Hz. The R-120SW provides RCA INPUT, which is a huge advantage when connecting the MacBook to the speakers on the shelf and subwoofer. I also connected the hardware synthesizer directly to the speakers on the shelf and the R-120SW, dividing the audio signal coming from the synthesizer output. So I got a really great sound image that fills the room, covering all frequencies, from very high treble to very low bass.

I did not expect so much power in one available package. The crossover function has no disadvantages. The assembly is strong, REALLY STRONG, the sound is musically accurate and powerful. It's really a solid bass, and I warn others if you have a lot of delicate decorations hanging on your walls or on the shelves, then it's a knock.

Performance & Sound quality

As for the sound, let me tell you: it's fantastic. For its price, it surpassed my expectations. This subwoofer is well suited for rock. He brings drums from your favorite concert to your home and provides hours of smiles. I really like the clean rumbling bass producing movies and games. Suddenly, the background sounds in a game or movie made me instinctively look out the window to check for rain.

The bass output from this subwoofer is excellent, deep enough for most applications and loud enough in a small/medium-sized room. Excellent sound, excellent synchronization with the main speakers, unnecessary crackles and unpleasant sounds. So my ears enjoyed the beautiful crash of the new sub from the very first minutes of use.


If we talk about R-120SW setup – it is very easy to install. This is a great subwoofer that is easy to plug in and blends perfectly with your other speakers. Worked immediately when connected to my system. Now, mind you, I'm not a music expert, but I like the performance of this subwoofer. The system sounds great. Sub goes very low and powerful.

The volume control on the side panel simplifies the bass level setting. A complete set of controls and connections allows you to connect and fully integrate with any stereo or multi-channel audio system and be tuned for optimal performance in any room.


Klipsch R-120SW settings were easy. This subwoofer is so loud, clear and accurate that I am almost upset, I have not received it before. The best home theater sub I've ever heard in this price range. Zero distortion and so accurately and effortlessly. I know that the cost is probably more than some people would spend on their living room system, but it's worth it. Highly recommended.
