Audiophile Quality Bass for Music and Home Theater

A subwoofer is a purpose-built loudspeaker solely responsible for playing low frequencies (bass). SVS sealed subwoofers deliver audiophile quality bass at massive output levels so you can hear and feel every heart-pounding or subtle detail with its full impact and clarity.

Sealed cabinet subwoofers are favorites of music lovers and home theater fans who crave punchy and pinpoint accurate bass that starts and stops on a dime. Sealed subwoofers are very effective at rendering musical instruments like bass guitars and kick drums in a convincing and natural way. These characteristics make the sealed subwoofer a natural choice for audiophiles and critical music applications.

Nearly all SVS sealed subwoofers play below 20Hz, the threshold of human hearing. Below this frequency, sound is only felt, and playback adds a deeply immersive, palpable effect that draws you further into movies, music and other audio experiences.

With a sealed subwoofer, the room itself also has the potential to boost bass below a certain frequency. You get more output than your subwoofer can produce by itself—for free. The effect is called “room gain” and the effect and how to optimize for is explained here, What is Room Gain?

Compared to ported cabinet subwoofers with similar sized drivers and amplifier power, sealed subwoofers are more compact and excel with punchiness, accuracy, and transient response. Ported subwoofers in comparison produce greater dynamic output and can generally play lower, but the cabinets are significantly larger. SVS is always narrowing the delta between ported and sealed subwoofer performance and for a more detailed explanation, check out the SVS Sound Experts article, Ported vs. Sealed Subwoofers.

Known as our “SB” (Sealed Box) models, SVS offers a range of sealed subwoofer options for all different home theaters and audio systems.

FAQ

A sealed subwoofer is a type of subwoofer cabinet that is completely airtight, meaning that the air inside the enclosure cannot escape, nor can any air from outside get in. This type of subwoofer cabinet produces a tighter and more accurate and controlled bass response, which is great for music enthusiasts who want to experience full range sound. The cabinet size of sealed subwoofers is also significantly smaller than ported enclosures. To learn more about sealed subwoofers, click here

Sealed subwoofers are generally considered better for audiophiles and critical music listening because they are more accurate in frequency response with less phase rotation resulting in tighter bass with better transient response. This allows them to render musical instruments in a more convincing way. To learn more about the benefits of sealed subwoofers, click here

Running sealed and ported subwoofers together in a stereo or home theater system is not recommended because it can cause the subwoofers to work against each other due to the different phase responses. This is especially true over the port tuning frequency of the ported subwoofer. It can actually result in less bass because the sound waves will cancel each other out over that bandwidth.

Subwoofer placement often depends on available floor space and competing variables like décor and visual impact considerations. The most common placement for a subwoofer is in the front of the room and usually results in the best blending with your main speakers. Front and rear corners of a room are also recommended areas for subwoofer placement. To learn more about subwoofer placement, click here.
