Seismic Output, Subterranean Low Frequency Extension

A subwoofer is a purpose-built loudspeaker solely responsible for playing low frequencies (bass). SVS ported subwoofers deliver massive, effortless bass while remaining accurate and refined so you can hear and feel every heart-pounding detail with its full impact and clarity.

Ported subwoofers are popular for users who enjoy pushing sound pressure levels (SPLs) to the max in a home theater environment and for music fans who want the deepest extension and most output possible. If you want to experience the full energy of every action movie explosion or the guttural feeling of a musical bass drop, an SVS ported subwoofer is ideal for you.

All SVS ported subwoofers (and 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.

Compared to sealed cabinet subwoofers with similar sized drivers and amplifier power, ported (or vented) subwoofers produce greater dynamic output and can generally play lower. Sealed subwoofers excel with punchiness, accuracy, and transient response, while being more compact in size. 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 “PB” (Ported Box) and “PC” (Ported Cylinder) models, SVS offers a range of ported subwoofer options for all different home theaters and audio systems.

A ported subwoofer, also known as a bass reflex subwoofer, is a type of subwoofer cabinet that uses tuned ports to improve the efficiency and extend the low-frequency response of the subwoofer. The port in the enclosure is carefully tuned to a specific length and diameter, which determines the resonant frequency of the system. This tuning process allows the port to reinforce specific low-frequency sounds, resulting in increased output and improved efficiency in that frequency range compared to sealed cabinet subwoofers.

Ported subwoofers are generally considered better for home theater and music with deep bass output, like EDM, because they produce more dynamic impact and deeper low frequency extension, especially at reference playback levels, while requiring less amplifier power to achieve the same volume levels as sealed enclosures. They are more efficient in converting electrical energy into sound output due to the resonance effect of the port. However, the trade-off is that ported subwoofers may not offer the same level of accuracy and tightness as sealed enclosures. Simply put, if you want the most room-energizing, gut-punching, floor-trembling cinematic experience possible, a ported subwoofer should be your choice. They are also more capable of filling larger spaces. To learn more about the benefits of ported subwoofers, click here

It is not recommended to run sealed and ported subwoofers in a home theater system. By mixing both cabinet types, it can cause the subwoofers to work against each other due to having very different phase responses, especially over the port tuning frequency of the ported subwoofer. The sound waves will cancel each other out over that bandwidth, and you’ll get reduced performance. To learn more about mixing ported and sealed subwoofers in a home theater, click here

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 as well. To learn more about subwoofer placement, click here.
