In this review, we will be comparing R-100SW and DB4S, two Powered Subwoofer speakers from Klipsch 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 Klipsch R-100SW and B&W DB4S first before getting into our more detailed comparison.
In the following sections, we will get into details in order to better understand how the Klipsch R-100SW and B&W DB4S 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.Klipsch R-100SWand B&W DB4S have the same driver set up: Both subwoofers have 1 x 10" drivers.
Frequency Response
R-100SW has a frequency range of 32-120 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 R-100SW's min frequency of 32Hz.
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 Klipsch R-100SW has a Bass reflex type cabinet. On the other hand the B&W DB4S have Acoustic Suspension type enclosure. 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
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 Klipsch R-100SW's and B&W DB4S's external dimensions. Klipsch R-100SW has external dimensions of 372.0 x 320.0 x 459.0mm ( 14-5/8 x 12-9/16 x 18-1/16inch) 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) .
Klipsch R-100SW is 42mm narrower and 3mm shorter than B&W DB4S but it is also 25mm 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 Klipsch R-100SW is approximately 1468.8cm2 / 227.7inch2 and base area of the B&W DB4S is approximately 1571.1cm2 / 243.5inch2. The R-100SW requires 7% 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 Klipsch R-100SW weighs 10.91kg / 24lbs and the B&W DB4S weighs 26.05kg / 57.3lbs. This makes the DB4S 139% heavier than the R-100SW.
Here is a comparison of how R-100SW and DB4S's weights compare with the average, max and min weights in Powered Subwoofer class.
