In this review, we will be comparing DB2D and RP-1200SW, 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 RP-1200SW first before getting into our more detailed comparison.
In the following sections, we will get into details in order to better understand how the B&W DB2D and Klipsch RP-1200SW compare and hopefully end up with enough arguments to decide which one of these subwoofers is the better choice for you.

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 RP-1200SW have a totally different setup: the B&W DB2D features 2 x 10-inch drivers whereas the RP-1200SW features 1 x 12-inch drivers.
Frequency Response
DB2D has a frequency range of 10-350 Hz whereas RP-1200SW has a frequency range of 16.5-138 Hz. With a minimum frequency of 10Hz, the DB2D can go significantly deeper on the low side and provide stronger bass compared to the RP-1200SW'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.

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 RP-1200SW 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
Size of a speaker can sometimes become 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 RP-1200SW'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 RP-1200SW has external dimensions of 482.0 x 432.0 x 659.0mm ( 18-15/16inch x 17inch x 25-15/16inch ) .
Klipsch RP-1200SW is clearly the larger of the two speakers. Its body is 1mm wider, 96mm taller and 249mm deeper than B&W DB2D.
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 RP-1200SW is approximately 2846.9cm2 / 441.3inch2. The DB2D requires 38% less surface area than the RP-1200SW 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 RP-1200SW weighs 31.18kg / 68.6lbs. This makes the DB2D 16% heavier than the RP-1200SW.
Here is a comparison of how DB2D and RP-1200SW's weights compare with the average, max and min weights in Powered Subwoofer class.
