In this review, we will be comparing PB17 Ultra R Evolution 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 PB17 Ultra R Evolution 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.Both SVS PB17 Ultra R Evolutionand SVS SB-1000 Pro have a single woofer setup however the SVS PB17 Ultra R Evolution's woofer is 17-inch whereas the SVS SB-1000 Pro features a 12-inch woofer.
Frequency Response
PB17 Ultra R Evolution has a frequency range of 14-220 Hz whereas SB-1000 Pro has a frequency range of 20-270 Hz. With a minimum frequency of 14Hz, the PB17 Ultra R Evolution can go significantly deeper on the low side and provide stronger bass compared to 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.

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 PB17 Ultra R Evolution's and SVS SB-1000 Pro's external dimensions. SVS PB17 Ultra R Evolution has external dimensions of 635.0 x 552.5 x 746.1mm () 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 PB17 Ultra R Evolution is clearly the larger of the two speakers. Its body is 221.5mm wider, 292mm taller and 344.1mm deeper than SVS SB-1000 Pro.
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 PB17 Ultra R Evolution is approximately 4122.2cm2 / 638.9inch2 and base area of the SVS SB-1000 Pro is approximately 1330.6cm2 / 206.2inch2. The PB17 Ultra R Evolution requires 210% 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 PB17 Ultra R Evolution weighs 74.71kg / 164.4lbs and the SVS SB-1000 Pro weighs 11.82kg / 26lbs. This makes the PB17 Ultra R Evolution 532% heavier than the SB-1000 Pro.
Here is a comparison of how PB17 Ultra R Evolution 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 PB17 Ultra R Evolution needs about 210% more floor area. SVS PB17 Ultra R Evolution stands 344mm further into the room. SVS PB17 Ultra R Evolution is 292mm 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 PB17 Ultra R Evolution goes deeper - 14Hz against 20Hz. Under 20Hz is felt more than heard - the bottom of a pipe organ and the bottom of a film mix. |
| Amplifier power | A | SVS PB17 Ultra R Evolution has the bigger amplifier - 2800W against 325W RMS, about 9.4dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | A | SVS PB17 Ultra R Evolution moves more air: 17" against 12" is 2.01x the cone area, not the 1.42x the diameters suggest. More area means the same output with less excursion, and less distortion with it. |
| Enclosure | depends | SVS PB17 Ultra R Evolution 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. |
| Cabinet size | depends | SVS SB-1000 Pro is about 83% 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 $3,000, about 80% less. |
A SVS PB17 Ultra R Evolution B SVS SB-1000 Pro
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 PB17 Ultra R Evolution measures better, SVS SB-1000 Pro costs about 80% 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 PB17 Ultra R Evolution 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. Two small subwoofers beat one big one in most rooms - a pair evens out the room modes in a way no single box can, whatever its specs. At $600 each, two SVS SB-1000 Pro cost about $1,200 against $3,000 for one of the other, which is worth a thought.
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.
