In this review, we will be comparing DB2D and DB3D, two Powered Subwoofer speakers by 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 B&W DB2D and B&W DB3D 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 B&W DB2Dand B&W DB3D have a double woofer setup however the B&W DB2D's woofer is 10-inch whereas the B&W DB3D features a 8-inch woofer.
Frequency Response
DB2D has a frequency range of 10-350 Hz whereas DB3D has a frequency range of 10-350Hz.
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 B&W DB2D and B&W DB3D 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 B&W DB2D's and B&W DB3D's external dimensions. B&W DB2D has external dimensions of 386.0 x 431.0 x 410.0mm (15-3/16inch x 16-15/16inch x 16-1/8inch) whereas B&W DB3D has external dimensions of 368.3 x 341.3 x 347.7mm ().
B&W DB2D is clearly the larger of the two speakers. Its body is 89.7mm wider, 17.7mm taller and 62.3mm deeper than B&W DB3D.
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 B&W DB2D is approximately 1767.1cm2 / 273.9inch2 and base area of the B&W DB3D is approximately 1186.7cm2 / 183.9inch2. The DB2D requires 49% more surface area than the DB3D 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 B&W DB2D weighs 36.09kg / 79.4lbs and the B&W DB3D weighs 25.05kg / 55.1lbs. This makes the DB2D 44% heavier than the DB3D.
Here is a comparison of how DB2D and DB3D'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.
B&W DB2D needs about 49% more floor area. B&W DB2D stands 62mm further into the room. B&W DB2D is 18mm taller.

Siblings in Bowers Wilkins's DB range - same design thinking, different size. It comes down to your room and your budget.
| Area | Better | Why |
|---|
| Bass depth | evenly matched | Effectively the same reach (10Hz vs 10Hz). |
| Amplifier power | evenly matched | Much the same amplifier (1000W vs 1000W RMS) - under 1dB apart. |
| Driver area | A | B&W DB2D moves more air: 2 x 10" against 2 x 8" is 1.56x the cone area, not the 1.25x 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 DB3D is about 36% 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 | B&W DB3D costs less - $3,499 against $4,499, about 22% less. |
A B&W DB2D B B&W DB3D
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: B&W DB2D measures better, B&W DB3D costs about 22% less. In a normal room, placement will make a bigger difference than the gap between these two. If placement is the constraint - a corner, behind a sofa, under a desk - B&W DB3D 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.
