In this review, we will be comparing SB 5000 R Evolution 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 SB 5000 R Evolution 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 SB 5000 R Evolutionand B&W DB4S have a single woofer setup however the SVS SB 5000 R Evolution's woofer is 15-inch whereas the B&W DB4S features a 10-inch woofer.
Frequency Response
SB 5000 R Evolution has a frequency range of 17-280 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 SB 5000 R Evolution's min frequency of 17Hz.
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 SB 5000 R Evolution's and B&W DB4S's external dimensions. SVS SB 5000 R Evolution has external dimensions of 465.1 x 452.4 x 495.3mm () 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).
SVS SB 5000 R Evolution is clearly the larger of the two speakers. Its body is 90.4mm wider, 90.1mm taller and 61.3mm deeper than B&W DB4S.
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 SB 5000 R Evolution is approximately 2240.7cm2 / 347.3inch2 and base area of the B&W DB4S is approximately 1571.1cm2 / 243.5inch2. The SB 5000 R Evolution requires 43% 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 SB 5000 R Evolution weighs 46.31kg / 101.9lbs and the B&W DB4S weighs 26.05kg / 57.3lbs. This makes the SB 5000 R Evolution 78% heavier than the DB4S.
Here is a comparison of how SB 5000 R Evolution and DB4S'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 SB 5000 R Evolution needs about 43% more floor area. SVS SB 5000 R Evolution stands 61mm further into the room. SVS SB 5000 R Evolution is 90mm taller.

Two quite different sizes of subwoofer. Room volume decides this more than anything else on the page: a big driver in a small room is wasted, and a small one in a large room is worked to death.
| Area | Better | Why |
|---|
| Bass depth | B | B&W DB4S goes deeper - 10Hz against 17Hz. Under 20Hz is felt more than heard - the bottom of a pipe organ and the bottom of a film mix. |
| Amplifier power | A | SVS SB 5000 R Evolution has the bigger amplifier - 2000W against 1000W RMS, about 3dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | A | SVS SB 5000 R Evolution moves more air: 15" against 10" is 2.25x the cone area, not the 1.5x the diameters suggest. More area means the same output with less excursion, and less distortion with it. |
| Enclosure | evenly matched | Both are sealed designs, so they roll off in much the same way. |
| Cabinet size | depends | B&W DB4S is about 43% 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 SB 5000 R Evolution 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 SB 5000 R Evolution costs less - $2,000 against $2,199, about 9% less. |
A SVS SB 5000 R Evolution 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?
SVS SB 5000 R Evolution has the edge on paper, though not by much. The "depends" rows are more likely to decide this than the score is. If placement is the constraint - a corner, behind a sofa, under a desk - B&W DB4S 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.
