In this review, we will be comparing DB2D and R-101SW, two Powered Subwoofer speakers from Bowers Wilkins and Klipsch. 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 Klipsch R-101SW 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.B&W DB2D and Klipsch R-101SW have a totally different setup: the B&W DB2D features 2 x 10-inch drivers whereas the R-101SW features 1 x 10-inch drivers.
Frequency Response
DB2D has a frequency range of 10-350 Hz whereas R-101SW has a frequency range of 29.5-160 Hz. With a minimum frequency of 10Hz, the DB2D can go significantly deeper on the low side and provide stronger bass compared to the R-101SW's min frequency of 30Hz.
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 B&W DB2D has a Acoustic Suspension type cabinet. 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. On the other hand the Klipsch R-101SW 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 B&W DB2D's and Klipsch R-101SW'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 Klipsch R-101SW has external dimensions of 370.0 x 358.0 x 529.0mm (14-9/16inch x 14-1/16inch x 20-13/16inch).
Klipsch R-101SW is 73mm narrower and 16mm shorter than B&W DB2D but it is also 119mm deeper.
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 Klipsch R-101SW is approximately 1893.8cm2 / 293.5inch2. The DB2D requires 7% less surface area than the R-101SW 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 B&W DB2D weighs 36.09kg / 79.4lbs and the Klipsch R-101SW weighs 13.91kg / 30.6lbs. This makes the DB2D 159% heavier than the R-101SW.
Here is a comparison of how DB2D and R-101SW'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.
Near-identical footprints. Klipsch R-101SW stands 119mm further into the room. B&W DB2D is 16mm taller.

A sealed 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 | A | B&W DB2D goes deeper - 10Hz against 30Hz. Under 20Hz is felt more than heard - the bottom of a pipe organ and the bottom of a film mix. |
| Amplifier power | A | B&W DB2D has the bigger amplifier - 1000W against 150W RMS, about 8.2dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | A | B&W DB2D moves more air: 2 x 10" against 10" is 2x the cone area, not the 1.41x the diameters suggest. More area means the same output with less excursion, and less distortion with it. |
| Enclosure | depends | B&W DB2D is sealed - a sealed box rolls off gently and is usually the easier one to integrate in a small or awkward room; Klipsch R-101SW 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. |
| Driver placement | depends | B&W DB2D fires side and Klipsch R-101SW fires front. A down-firing driver is more forgiving of a grille-less look and of a hard floor; a front-firing one is the safer choice on a thick carpet or a suspended timber floor. |
| Price | B | Klipsch R-101SW costs less - $499 against $4,499, about 89% less. |
A B&W DB2D B Klipsch R-101SW
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, Klipsch R-101SW costs about 89% less. In a normal room, placement will make a bigger difference than the gap between these two. Films or music? If this is mainly a home cinema, Klipsch R-101SW will hit harder for the money; if it is mainly for music in a normal-sized room, B&W DB2D 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 $499 each, two Klipsch R-101SW cost about $998 against $4,499 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.
