When it comes to adding deep, rich bass to your home entertainment system, subwoofers make all the difference. Today, we're comparing two popular but very different approaches: the newer wireless Polk Audio React Subwoofer ($199) and the traditional Klipsch Reference R-120SW ($215).
Subwoofers have come a long way from the massive boxes that dominated living rooms in the 1990s. The Klipsch R-120SW, released around 2018, represents a refined version of the traditional powered subwoofer design. Meanwhile, the newer Polk React, part of their wireless ecosystem launched in 2021, showcases how modern connectivity is changing home audio.
The Polk React takes a modern, wireless-first approach. It's designed specifically to pair with Polk's React soundbar, using automatic wireless connection and smart features like Alexa voice control. This integration comes at the cost of flexibility - you can't use it with other systems.
The Klipsch R-120SW follows the traditional powered subwoofer path. It connects via standard RCA or LFE (Low Frequency Effects) cables and works with virtually any audio system. While this means dealing with cables, it offers broader compatibility and typically better performance for the price.
The physics of bass reproduction heavily favor the Klipsch here. Its 12-inch driver moves significantly more air than the Polk's 7-inch unit. Think of it like comparing a large fan to a small one - both move air, but the larger one can move more with less effort.
The Klipsch's 200-watt RMS amplifier (with 400-watt peaks) delivers substantial power. While Polk doesn't specify their amplifier power, the laws of physics suggest it's likely in the 100-150 watt range given the driver size. This difference becomes noticeable when:
The Klipsch can reach down to 29Hz, while the Polk likely bottoms out around 35-40Hz. This might seem like a small difference, but those extra low frequencies add real weight to movie soundtracks and certain types of music.
Both subwoofers take different approaches to sound quality:
The Polk uses sophisticated digital signal processing (DSP) and automatic EQ adjustment to optimize its performance within its limitations. This helps it deliver clean, controlled bass that works well in smaller rooms. Its wireless nature also eliminates potential ground loop hum issues that can plague wired setups.
The Klipsch relies more on raw mechanical capability. Its spun-copper IMG (Injection Molded Graphite) woofer is extremely rigid yet lightweight, allowing for precise movement even during demanding passages. The front-firing design and substantial cabinet volume help it deliver more impactful bass.
The Polk React shines in setup simplicity:
The Klipsch R-120SW requires more consideration:
However, this extra setup complexity brings benefits:
Room size and shape significantly impact subwoofer performance. The Polk works best in:
The Klipsch excels in:
The Polk integrates with Amazon Alexa for voice control of:
The Klipsch offers traditional manual controls:
Both units take different approaches to cabinet design:

The subwoofer market continues to evolve. The Polk represents the trend toward wireless, smart-home integration, while the Klipsch shows how traditional designs can be refined for modern needs. Looking forward, we'll likely see:
However, the physics of moving air won't change - larger drivers and more powerful amplifiers will always have advantages for pure performance.
Both these subwoofers excel in their intended use cases. The choice ultimately depends on your specific needs, room constraints, and whether you value wireless convenience over maximum performance.
