The Fosi Audio SW10 is a high-performance active subwoofer designed to bring dynamic, powerful, and accurate low-frequency effects to your home audio setup. Whether you are building an immersive home theater system or enhancing your music listening experience, the SW10 delivers the impactful bass you need.
Powerful Performance: Equipped with a built-in 200-watt (RMS) Class D amplifier, the SW10 provides clean, continuous power to drive the 10-inch cone, ensuring earth-shaking yet controlled bass.

Yes, the Fosi Audio SW10 is designed for high compatibility. It features multiple input options, including RCA and High-Level inputs, allowing it to integrate seamlessly with both modern home theater receivers and vintage stereo amplifiers. Whether your amplifier has a dedicated "Sub Out" or only standard speaker terminals, the SW10 can be connected to provide that essential low-frequency support.
The adjustable Crossover frequency is key to achieving a "seamless" sound. It allows you to define exactly where your main speakers stop playing and where the SW10 takes over. By tuning this dial, you can prevent the mid-bass from becoming "muddy" or "boomy," ensuring that the transition between your bookshelf speakers and the subwoofer is smooth, natural, and perfectly balanced for your room's acoustics.
The SW10 is an active (powered) subwoofer, meaning it has its own high-performance power amplifier built directly into the cabinet. You do not need an external amplifier to drive it; you simply plug it into a power outlet and connect your audio signal. This independent power supply ensures that the 10-inch driver has consistent, dedicated energy to produce tight, controlled, and impactful bass without straining your main amplifier.
While bass is omnidirectional, placement significantly affects performance. For the most impactful "room-filling" bass, placing the SW10 near a corner can enhance its output. However, to achieve the most accurate and musical response, many users prefer placing it along the front wall between the main speakers. The SW10 also features a Phase switch (0°/180°), which helps synchronize the subwoofer with your main speakers regardless of where it is placed.
Absolutely. The Fosi Audio SW10 is engineered for versatility. Its 10-inch long-throw driver is responsive enough to handle the subtle nuances and fast transients of musical bass (like a kick drum or upright bass), while also possessing the power and excursion necessary to deliver the deep, cinematic rumbles found in modern movie soundtracks. It effectively turns a standard 2.0 system into a full-range 2.1 powerhouse.
