Unboxing the Klipsch R-120SW Subwoofer

After getting a lot of requests from you guys regarding the best 12-inch home theater setup, we knew it has to be from the Klipsch. We were so excited about this package after seeing our fellow mates using this beast, so when it arrived after almost 2.5 weeks, we instantly unpacked it. 

Though it was a large and heavy box, unboxing it was worth every minute we spent on it. The best-priced subwoofer came in a well-designed box that had all the information about the product, including its specifications and what’s inside it. 

The packaging material was well settled, and a silicon bag including a user manual, 3 x power cables, and connectivity cables was also at the top of the box. 

Size and Design

Subwoofers come in different shapes, designs, and sizes, so choosing the one that best fits your environment can upscale your experience.

The Klipsch R-120SW comes in an MDF cabinet that is covered in glossy vinyl material, but its scratch-resistant material has all the points. There is no risk of fingerprints ruining its looks, so you can expect the front-firing design enclosure can complement the home and bring life to the home theater setup.

In addition, it may be quite heavy as it weighs around 31 pounds, but we didn’t face hassle sliding it into the sweet spot, thanks to the rubber feet. The front grill was not top quality, but it doesn’t matter as long as it shields the driver beneath.

Built-in Driver and Amp

A subwoofer has become an essential part of any home theater system. It is designed to reproduce the lowest frequencies in a song, providing the foundation for all the other sounds in the mix.

Therefore, it has to be powerful, reliable, and capable of producing high power output to have a personalized premium listening experience.

That being said, Klipsch R-120SW contains a lightweight IMG subwoofer powered by a 400W built-in digital amplifier that fuels the power to the woofer so it can perform without any risk of damage.

Power Output

Klipsch R-120SW is a high-performance subwoofer that can create an incredible listening experience whether you listen to music, watch movies, or play intense high-end games.

The 12-inch woofer has a power output of 400W at peak, the highest level a subwoofer can offer, and handle with a 200W RMS power that indicates the subwoofer handling capacity at maximum.

With this high power output, you can expect a deep bass with no distortions and compressions at any volume level and excellent accuracy for the premium acoustics.

Connectivity Sources

A subwoofer is a unique type of speaker that only focuses on a certain frequency range, particularly the lowest ones, so better to treat it like the regular ones.

Like other speakers, it requires creating a stable connection with a receiver, followed by plugging it into the compatible voltage for a safe user experience.

For connectivity, it offers LFE/RCA cable inputs that shouldn’t bother you during the connection phase. Thankfully, we had a safe pairing process with an RCA cable, and the sound quality wasn’t compromised a bit.

Controls Onboard 

The best thing about Klipsch subwoofers is the add-ons that justify their price tag and offer the best possible listening experience. Like any high-end sound system, you can customize the sound and bass performance to use the control levels.

It offers variable low pass, gain control dial and phase switch for making some usual adjustments. The volume knob allows you to adjust the volume level according to the bass delivery, so you can have the most out of it.


Klipsch R-120SW deserves appreciation for being the top-class subwoofer that can handle the lowest frequencies pretty well and surprise you with precise bass notes with great accuracy and rich tuning.

With a frequency response range of 29Hz – 120Hz at +/- 3dB, the sound can be exciting, deep, and hard-hitting to bang the windows.

We tested the subwoofer with classical musicals and were amazed by the performance. The clear and powerful bass tones were highly noticeable. There was no sign of distortions, and the notes were perfectly aligned with the upper and mid-range frequencies.


The high-quality material and excellent construction of the Klipsch R-120SW subwoofer keep the brand’s reputation intact, but to stay on the safe side, the subwoofer comes with a product warranty.

It provides a 5-year warranty on the woofer and a 2-years warranty on a built-in class-D digital amplifier. It further polishes the consumer’s trust in the brand and makes it stand out in the market.


We love the Klipsch packaging policy. The product came absolutely safely, and we enjoyed unpacking the beast. The 31 pounds subwoofer is quite challenging to handle at first, but once you put it on the floor and attach the grill, it starts showing its charm.

Besides, unpacking such products is always fun for us. The box included a 12-inch powered subwoofer packed in a ported enclosure, a detachable cover, a power cord, an AC adapter, and an instructions manual. The warranty card also comes with a product.

• Decent-looking subwoofer
• IMG woofer material
• •RCA connection
• 5-year warranty
• Affordable
• Rubber feet for smooth movement
• A little heavy
• Sound below 29Hz is hard to listen

Bottom Line

When choosing a subwoofer, it is important to consider many options, like the subwoofer size, power output, and performance for music and movies. The frequency response range is also important, but the bass quality to add some extra thump to your music matters the most.

We found everything in Klipsch R-120SW that one reasonably-priced subwoofer for home theater should have. It is a well-built, durable, and high-powered subwoofer that can be a game-changer for your music streaming.

So, what are you waiting for?
