In this review, we will be comparing SB-1000 Pro 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-1000 Pro 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-1000 Proand B&W DB4S have a single woofer setup however the SVS SB-1000 Pro's woofer is 12-inch whereas the B&W DB4S features a 10-inch woofer.
Frequency Response
SB-1000 Pro has a frequency range of 20-270 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-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
Both SVS SB-1000 Pro and B&W DB4S have Acoustic Suspension type cabinets. 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 SB-1000 Pro's and B&W DB4S's external dimensions. 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) 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 clearly the larger of the two speakers. Its body is 31mm wider, 32mm taller and 32mm deeper than SVS SB-1000 Pro.
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.
B&W DB4S needs about 18% more floor or shelf area. B&W DB4S is 32mm deeper, so it stands that much further out from the wall. B&W DB4S is 32mm 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 SB-1000 Pro is approximately 1330.6cm2 / 206.2inch2 and base area of the B&W DB4S is approximately 1571.1cm2 / 243.5inch2. The SB-1000 Pro requires 15% less surface area than the DB4S 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 SVS SB-1000 Pro weighs 11.82kg / 26lbs and the B&W DB4S weighs 26.05kg / 57.3lbs. This makes the DB4S 120% heavier than the SB-1000 Pro.
Here is a comparison of how SB-1000 Pro and DB4S's weights compare with the average, max and min weights in Powered Subwoofer class.

Different price classes - B&W DB4S costs roughly 3.7x what SVS SB-1000 Pro does. Before paying it, read the note below about two smaller subwoofers.
| Area | Better | Why |
|---|
| Bass depth | B | B&W DB4S goes deeper - 10Hz against 20Hz. 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 325W RMS, about 4.9dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | A | SVS SB-1000 Pro 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 | evenly matched | Both are sealed designs, so they roll off in much the same way. |
| Setup and tuning | evenly matched | The same tuning tools on both (app control). |
| Speaker-level inputs | A | SVS SB-1000 Pro 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 SB-1000 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 | SVS SB-1000 Pro is about 23% 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-1000 Pro 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-1000 Pro costs less - $600 against $2,199, about 73% less. |
A SVS SB-1000 Pro 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-1000 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, SVS SB-1000 Pro is the only one of these two you can connect at all. 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 $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.
