When setting up a home audio system, few components make as dramatic an impact as a quality subwoofer. Today, we're comparing two distinct approaches from Klipsch: the compact and wireless-ready Flexus SUB 100 at $239 and the theater-grade Reference Premiere RP-1200SW at $706.
Subwoofers handle the lowest frequencies in your audio system - those deep bass notes in music and thunderous effects in movies that you can physically feel. While both of these models achieve this goal, they take notably different approaches.
The key factors that determine subwoofer performance include:
The RP-1200SW reaches down to an impressive 16.5Hz, while the Flexus SUB 100 bottoms out around 26Hz. This difference is significant - those extra low octaves add substantial impact to movie explosions and give pipe organs their full grandeur. The RP-1200SW's Cerametallic woofer (a specialized aluminum-ceramic composite) provides exceptional rigidity for cleaner bass compared to the Flexus's paper cone design.
The difference in maximum output (121dB vs 103.7dB) represents a massive real-world gap. The RP-1200SW can fill large rooms with authoritative bass, while the Flexus SUB 100 is better suited to small and medium spaces. Think of it like this: the RP-1200SW has roughly four times the acoustic power.
With 400W RMS (800W peak) versus 80W RMS (160W peak), the RP-1200SW has substantially more power on tap. This translates to better control over the woofer and more headroom for dynamic content. The analog preamp stage in the RP-1200SW helps maintain signal purity, while both units use efficient Class D amplification.
The Flexus SUB 100's compact 13-inch cube design makes it incredibly versatile for placement. At just 20.7 pounds, it's easy to position or relocate. The RP-1200SW, weighing 68.6 pounds and nearly twice the size in each dimension, demands more careful placement planning.
The Flexus SUB 100 shines in its wireless implementation, designed specifically for seamless integration with Flexus soundbars. The low-latency wireless connection works remarkably well, and you can even add a second sub for more even bass distribution.
The RP-1200SW takes a more traditional approach with its LFE/RCA inputs, though it offers an optional wireless adapter. Its front-firing port design with "Aerofoil" technology (which reduces port noise through carefully engineered internal geometry) provides more flexibility in placement near walls.
The RP-1200SW, released in 2023, incorporates several advanced features:
The Flexus SUB 100, part of Klipsch's newer lifestyle audio line, focuses on:
In practice, the RP-1200SW delivers the kind of performance that can anchor a serious home theater system. Its additional power and extension are immediately noticeable on demanding content. Bass notes are more defined, with better separation between rapid beats and more impact on explosive effects.
The Flexus SUB 100 impresses in its own right, particularly given its size and price point. It integrates exceptionally well with Flexus soundbars and provides satisfying bass for music and movies in smaller spaces. The wireless capability works flawlessly, with no noticeable lag or dropout issues.
At $239, the Flexus SUB 100 represents excellent value for:
At $706, the RP-1200SW justifies its premium for:

The Klipsch Flexus SUB 100 at $239 is ideal for small rooms due to its compact size and 103.7dB output. The RP-1200SW at $706 would be overkill in spaces under 300 square feet.
The RP-1200SW reaches deeper bass (16.5Hz vs 26Hz) and plays much louder (121dB vs 103.7dB) than the Flexus SUB 100. This difference is most noticeable in movie effects and deep musical bass.
The Flexus SUB 100 offers simpler setup with its wireless connectivity and lightweight design. The RP-1200SW requires more planning due to its size and traditional wired connections.
The RP-1200SW justifies its higher price for larger rooms and serious home theater use. For apartments and smaller spaces, the Flexus SUB 100 provides better value.
The Flexus SUB 100 is specifically designed to work with Klipsch Flexus soundbars, offering seamless wireless integration. The RP-1200SW is better suited for traditional home theater receivers.
Both work well for music, but the RP-1200SW offers better definition and deeper bass. The Flexus SUB 100 is adequate for most musical styles in smaller rooms.
The RP-1200SW comes with a 5-year warranty, while the Flexus SUB 100 includes a 2-year warranty.
The Flexus SUB 100 is more apartment-friendly due to its smaller size and controlled output. The RP-1200SW might be too powerful for apartment living.
The Flexus SUB 100 works best with Flexus soundbars, while the RP-1200SW connects to any standard AV receiver with a subwoofer output.
The RP-1200SW features premium materials like a Cerametallic woofer and superior cabinet construction. The Flexus SUB 100 is well-built but uses more basic materials.
The Flexus SUB 100 offers more placement flexibility due to its compact size and wireless capability. The RP-1200SW requires more careful placement due to its size and front-firing port.
The RP-1200SW is built for longevity with higher-grade components and a longer warranty. The Flexus SUB 100 should still provide many years of service with proper care.
