SVS SB-1000 Pro vs PB-1000 Pro: A Detailed Comparison

SVS, a renowned name in the world of audio, has consistently produced high-quality subwoofers that cater to the demands of audiophiles and home theater enthusiasts. Among their popular offerings are the SVS SB-1000 Pro and PB-1000 Pro, each with distinct features and designs tailored to meet specific audio preferences and requirements. In this article, we'll delve into a detailed comparison of these two models to help you make an informed decision based on your preferences and listening needs.

Design and Enclosure Type

The design and enclosure type of a subwoofer significantly impact its performance and application suitability.

SB-1000 Pro:

The SB-1000 Pro is a sealed box (SB) subwoofer, known for its precision and accuracy in reproducing bass frequencies. The sealed enclosure ensures a tight and controlled bass response, making it ideal for critical listening and music enthusiasts. The absence of ports in the design minimizes air turbulence and provides a more controlled transient response.

PB-1000 Pro:

On the other hand, the PB-1000 Pro is a ported box (PB) subwoofer, designed to deliver powerful and extended bass. The ported enclosure allows for greater low-frequency extension, resulting in a more pronounced and dynamic bass output. Ported subwoofers are well-suited for home theater applications and provide a visceral experience during intense movie scenes and soundtracks.

Bass Output and Extension

The bass output and extension of a subwoofer are critical factors that determine its ability to reproduce deep and impactful low frequencies.

SB-1000 Pro:

The sealed enclosure of the SB-1000 Pro provides a balanced and precise bass response. While it may not reach the same depth as a ported subwoofer, it offers a clean and tight bass that is ideal for audiophiles and those who prioritize accuracy in their audio reproduction.

PB-1000 Pro:

With its ported design, the PB-1000 Pro achieves a more extended low-frequency response and higher overall output compared to the SB-1000 Pro. This makes it an excellent choice for enthusiasts seeking powerful and room-filling bass, especially for home theater applications where deep bass is crucial.

Size and Form Factor

The size and form factor of a subwoofer can greatly impact its placement and integration into your living space.

SB-1000 Pro:

Sealed box subwoofers like the SB-1000 Pro tend to be more compact in size compared to their ported counterparts. This makes them easier to accommodate in smaller rooms or where space is limited. The smaller size also allows for greater flexibility in placement options.

PB-1000 Pro:

Ported subwoofers like the PB-1000 Pro are typically larger due to the additional space needed for the port. While the larger size may be a consideration, it's a trade-off for the enhanced bass output and extension. It's important to ensure you have adequate space for this subwoofer in your listening area.

Placement Flexibility

The flexibility of subwoofer placement can significantly impact the overall sound quality and integration with your existing audio setup.

SB-1000 Pro:

Sealed box subwoofers are generally more forgiving when it comes to placement. The absence of ports means they are less susceptible to room effects, allowing for more flexibility in finding the optimal placement that suits your room acoustics.

PB-1000 Pro:

Ported subwoofers, while offering powerful bass, may require more careful consideration regarding placement to achieve the best performance. The ported design can be influenced by the room's acoustics, making placement critical to achieving optimal bass response.


In conclusion, the choice between the SVS SB-1000 Pro and PB-1000 Pro ultimately depends on your specific preferences and how you intend to use the subwoofer. If you prioritize precise and accurate bass reproduction, particularly for music and critical listening, the SB-1000 Pro's sealed design is a solid choice. On the other hand, if you seek deep, powerful bass for a thrilling home theater experience, the PB-1000 Pro's ported design with extended low-frequency response is likely to better suit your needs.

Consider factors such as your room size, listening preferences, and available space when making your decision. Both models reflect SVS's commitment to quality and performance, ensuring an immersive audio experience, whether you're enjoying music or movie night at home.

Frequency Response and Output:

SB-1000 Pro: The sealed enclosure of the SB-1000 Pro provides accurate and controlled bass response. It has a frequency response of around 20Hz to 270Hz (±3dB) and can deliver powerful, tight bass for both music and movies.

PB-1000 Pro: The ported design of the PB-1000 Pro allows for deeper bass extension. It has a frequency response of around 17Hz to 260Hz (±3dB) and can produce more output in the lower frequency range, making it well-suited for home theater applications and larger rooms.

Room Size and Application:

SB-1000 Pro: Due to its sealed design, the SB-1000 Pro works well in smaller to medium-sized rooms and is suitable for both music and movies.svs sb 1000 pro vs pb 1000 pro

PB-1000 Pro: The PB-1000 Pro's ported design and higher output make it better suited for larger rooms and home theater setups, where it can provide more impactful and immersive bass.

Ultimately, the choice between the SVS SB-1000 Pro and PB-1000 Pro depends on your specific requirements, room size, and intended use. If you have a smaller room or prefer tighter, more controlled bass, the SB-1000 Pro is a great choice. On the other hand, if you have a larger room or prioritize deep bass extension and higher output, the PB-1000 Pro may be a better fit.
