In this review, we will be comparing PC-2000 and DB4S, two Powered Subwoofer speakers from SVS and Bowers Wilkins. 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 PC-2000 and B&W DB4S 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 PC-2000and B&W DB4S have a single woofer setup however the SVS PC-2000's woofer is 12-inch whereas the B&W DB4S features a 10-inch woofer.
Frequency Response
PC-2000 has a frequency range of 16-260 Hz whereas DB4S has a frequency range of 10-350 Hz. With a minimum frequency of 10Hz, the DB4S can go significantly deeper on the low side and provide stronger bass compared to the PC-2000's min frequency of 16Hz.
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 PC-2000 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 B&W DB4S 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 PC-2000's and B&W DB4S's external dimensions. SVS PC-2000 has external dimensions of 872.0 x 422.0 x 422.0mm (34-5/16 x 16-5/8 x 16-5/8inch) whereas B&W DB4S has external dimensions of 375.0 x 362.0 x 434.0mm (14-3/4 x 14-1/4 x 17-1/16inch).
B&W DB4S is 60mm narrower and 497mm shorter than SVS PC-2000 but it is also 12mm deeper.
Size, drawn to scale
Both speakers 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 surface and pushed back to the same wall, so the deeper one visibly sticks out further.
SVS PC-2000 needs about 13% more floor or shelf area. SVS PC-2000 is 497mm taller.
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 PC-2000 is approximately 1780.8cm2 / 276.0inch2 and base area of the B&W DB4S is approximately 1571.1cm2 / 243.5inch2. The PC-2000 requires 13% more surface area than the DB4S 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 PC-2000 weighs 22.70kg / 49.9lbs and the B&W DB4S weighs 26.05kg / 57.3lbs. This makes the DB4S 15% heavier than the PC-2000.
Here is a comparison of how PC-2000 and DB4S's weights compare with the average, max and min weights in Powered Subwoofer class.

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 | B | B&W DB4S goes deeper - 10Hz against 16Hz. Under 20Hz is felt more than heard - the bottom of a pipe organ and the bottom of a film mix. |
| Amplifier power | B | B&W DB4S has the bigger amplifier - 1000W against 500W RMS, about 3dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | A | SVS PC-2000 moves more air: 12" against 10" is 1.44x the cone area, not the 1.2x the diameters suggest. More area means the same output with less excursion, and less distortion with it. |
| Enclosure | depends | SVS PC-2000 is ported - a ported box gives more output low down for its size, at the cost of a steeper roll-off below tuning; B&W DB4S 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 | B&W DB4S is about 62% 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 | A | SVS PC-2000 carries 5 years on parts against 2 years. A subwoofer amplifier works harder than anything else in the system, so this is not a throwaway line. |
| Price | A | SVS PC-2000 costs less - $750 against $2,199, about 66% less. |
A SVS PC-2000 B B&W DB4S
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?
Neither runs away with it - they trade advantages. Let your room size and where the box can actually stand settle it. Films or music? If this is mainly a home cinema, SVS PC-2000 will hit harder for the money; if it is mainly for music in a normal-sized room, B&W DB4S 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 $750 each, two SVS PC-2000 cost about $1,500 against $2,199 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.
