In this review, we will be comparing PB-1000 Pro and SB-1000 Pro, two Powered Subwoofer speakers by SVS. Being Powered subwoofers, they both have built-in amplifiers so you don't need an external power amp or an integrated amp to power them. Let's have a brief look at the main features of SVS PB-1000 Pro and SVS SB-1000 Pro first before getting into our more detailed comparison.
The sections below take each area in turn: driver and amplifier, frequency response, physical size and connectivity.
Drivers
The efficiency of a subwoofer is directly proportional to the total radiating are squared hence the woofer quantity and diameter.SVS PB-1000 Proand SVS SB-1000 Pro have the same driver set up: Both subwoofers have 1 x 12" drivers.
Frequency Response
PB-1000 Pro has a frequency range of 17-260 Hz whereas SB-1000 Pro has a frequency range of 20-270 Hz. With a minimum frequency of 17Hz, the PB-1000 Pro can go slightly deeper then the SB-1000 Pro's min frequency of 20Hz.
Below graphs depict how these two speakers compare with the max, min and average values of the Min and Max Frequencies of other speakers in the Subwoofer class in our database.

Cabinet Type
The SVS PB-1000 Pro has a Bass Reflex type cabinet. Bass Reflex type subwoofers (aka Ported, Vented or Reflex Port) have enclosures that uses a port, hole or vent cut into the cabinet. Ported designs are generally more efficient than the Sealed designs. On the other hand the SVS SB-1000 Pro have Acoustic Suspension type enclosure. Acoustic Suspension aka Sealed type subwoofers have enclosures that are sealed hence no ports or holes exists on the cabinet. Sealed designs helps to provide more accurate and tight bass responses compared to ported designs.
Physical Specs
The size of a speaker can sometimes be an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare SVS PB-1000 Pro's and SVS SB-1000 Pro's external dimensions. SVS PB-1000 Pro has external dimensions of 479.0 x 380.0 x 509.0mm (18-13/16inch x 15inch x 20-15/16inch) whereas SVS SB-1000 Pro has external dimensions of 343.0 x 331.0 x 402.0mm (13-1/2inch x 13inch x 15-13/16inch).
SVS PB-1000 Pro is clearly the larger of the two speakers. Its body is 49mm wider, 136mm taller and 107mm deeper than SVS SB-1000 Pro.
Below you can see the front view size comparison of SVS PB-1000 Pro and SVS SB-1000 Pro in scale.

Base Surface Area Comparison
Base surface area of a loudspeaker may become a determining factor when the space in your room or desk is limited.
The base surface area of the SVS PB-1000 Pro is approximately 1934.2cm2 / 299.8inch2 and base area of the SVS SB-1000 Pro is approximately 1330.6cm2 / 206.2inch2. The PB-1000 Pro requires 45% more surface area than the SB-1000 Pro which gives it a small disadvantage on placement in tight spaces.
Weight Comparison The weight of a subwoofer may become an important factor if you need to move and reposition the unit often to find the optimal positioning, also known as 'Subwoofer Crawling'. The SVS PB-1000 Pro weighs 19.30kg / 42.5lbs and the SVS SB-1000 Pro weighs 11.82kg / 26lbs. This makes the PB-1000 Pro 63% heavier than the SB-1000 Pro.
Here is a comparison of how PB-1000 Pro and SB-1000 Pro's weights compare with the average, max and min weights in Powered Subwoofer class.

Size, drawn to scale
Both subwoofers and both views share one scale, so everything here is directly comparable. Hover a box for its dimensions.
One scale for both, standing on the same floor and pushed back to the same wall, so the bigger one visibly takes more of the room.
SVS PB-1000 Pro needs about 45% more floor area. SVS PB-1000 Pro stands 107mm further into the room. SVS PB-1000 Pro is 136mm taller.

A ported subwoofer against a sealed one. That is the most consequential line on this page: it decides how the bass rolls off, how it behaves in a small room, and how much output you get for the size of the box.
| Area | Better | Why |
|---|
| Bass depth | A | SVS PB-1000 Pro goes deeper - 17Hz against 20Hz. Under 20Hz is felt more than heard - the bottom of a pipe organ and the bottom of a film mix. |
| Amplifier power | evenly matched | Much the same amplifier (325W vs 325W RMS) - under 1dB apart. |
| Driver area | evenly matched | Near-identical radiating area (12" against 12"). |
| Enclosure | depends | SVS PB-1000 Pro is ported - a ported box gives more output low down for its size, at the cost of a steeper roll-off below tuning; SVS SB-1000 Pro is sealed - a sealed box rolls off gently and is usually the easier one to integrate in a small or awkward room. Neither is better in the abstract; ported tends to suit films and sealed tends to suit music, and both generalisations have exceptions. |
| Setup and tuning | evenly matched | The same tuning tools on both (room correction, onboard DSP and app control). |
| Cabinet size | depends | SVS SB-1000 Pro is about 51% smaller by volume. In a subwoofer that is a real trade rather than a preference: box volume is how you get output low down without a bigger amplifier. |
| Price | B | SVS SB-1000 Pro costs less - $600 against $799, about 25% less. |

depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both subwoofers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
The usual trade-off: SVS PB-1000 Pro measures better, SVS SB-1000 Pro costs about 25% less. In a normal room, placement will make a bigger difference than the gap between these two. Films or music? If this is mainly a home cinema, SVS PB-1000 Pro will hit harder for the money; if it is mainly for music in a normal-sized room, SVS SB-1000 Pro is usually the easier one to make sound right. If placement is the constraint - a corner, behind a sofa, under a desk - SVS SB-1000 Pro is the one that will actually go there, and a well-placed small subwoofer beats a badly-placed big one every time.
One thing outweighs everything above: where the subwoofer stands. Room modes can add or remove 10dB or more at a given seat, which is far larger than any difference on this page. Before spending more, try the sub in two or three positions - the crawl test, where you put it in the listening seat and crawl the room to find where the bass sounds best, costs nothing and usually beats an upgrade.
