In this review, we will be comparing Descend DN12 and PB-2000 Pro, two Powered Subwoofer speakers from Definitive Technology and 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 Definitive DN12 and SVS PB-2000 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.Definitive DN12and SVS PB-2000 Pro have the same driver set up: Both subwoofers have 1 x 12" drivers.
Frequency Response
Descend DN12 has a frequency range of 25-150 Hz whereas PB-2000 Pro has a frequency range of 16-290 Hz. With a minimum frequency of 16Hz, the PB-2000 Pro can go significantly deeper on the low side and provide stronger bass compared to the Descend DN12's min frequency of 25Hz.
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 Definitive DN12 has a Passive Radiator type cabinet. Passive Radiator type subwoofers sports a non-powered cone that moves in response to the main woofer to move air out in order to generate stronger bass in a smaller body compared to ported or sealed designs. On the other hand the SVS PB-2000 Pro have Bass Reflex type enclosure. 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.
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 Definitive DN12's and SVS PB-2000 Pro's external dimensions. Definitive DN12 has external dimensions of 488.0 x 459.0 x 512.0mm (19-3/16inch x 18-1/16inch x 20-1/8inch) whereas SVS PB-2000 Pro has external dimensions of 534.0 x 442.0 x 609.0mm (21 x 17-3/8 x 23-15/16inch).
Definitive DN12 is 46mm shorter and 97mm less deeper than SVS PB-2000 Pro but it is also 17mm wider.

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 Definitive DN12 is approximately 2350.1cm2 / 364.3inch2 and base area of the SVS PB-2000 Pro is approximately 2691.8cm2 / 417.2inch2. The Descend DN12 requires 13% less surface area than the PB-2000 Pro which gives it a small advantage 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 Definitive DN12 weighs 33.23kg / 73.1lbs and the SVS PB-2000 Pro weighs 29.45kg / 64.8lbs. This makes the Descend DN12 13% heavier than the PB-2000 Pro.
Here is a comparison of how Descend DN12 and PB-2000 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-2000 Pro needs about 15% more floor area. SVS PB-2000 Pro stands 97mm further into the room. SVS PB-2000 Pro is 46mm taller.

A passive radiator subwoofer against a ported 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 | B | SVS PB-2000 Pro goes deeper - 16Hz against 25Hz. 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 (500W vs 550W RMS) - under 1dB apart. |
| Driver area | evenly matched | Near-identical radiating area (12" against 12"). |
| Enclosure | depends | Definitive DN12 is passive radiator - a passive radiator behaves like a port without the pipe noise, and suits a slim cabinet; SVS PB-2000 Pro is ported - a ported box gives more output low down for its size, at the cost of a steeper roll-off below tuning. Neither is better in the abstract; ported tends to suit films and sealed tends to suit music, and both generalisations have exceptions. |
| Speaker-level inputs | A | Definitive DN12 takes a speaker-level connection as well as line level. That is what lets it work with an integrated amplifier or a vintage receiver that has no subwoofer output at all. |
| Wireless option | depends | Only SVS PB-2000 Pro offers a wireless link (as a paid option). It decides where the sub can go if you cannot run a cable, and is worth nothing if you can. |
| Cabinet size | depends | Definitive DN12 is about 20% 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. |
| Warranty | B | SVS PB-2000 Pro carries 5 years on parts against 3 years. A subwoofer amplifier works harder than anything else in the system, so this is not a throwaway line. |
| Price | B | SVS PB-2000 Pro costs less - $1,100 against $1,199, about 8% less. |
A Definitive DN12 B SVS PB-2000 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?
SVS PB-2000 Pro has the edge on paper, though not by much. The "depends" rows are more likely to decide this than the score is. Check your amplifier first: if it has no subwoofer or preamp output, Definitive DN12 is the only one of these two you can connect at all.
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.
