In this review, we will be comparing RP-1600SW 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 RP-1600SW 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 RP-1600SW 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.Both Klipsch RP-1600SWand B&W DB4S have a single woofer setup however the Klipsch RP-1600SW's woofer is 16-inch whereas the B&W DB4S features a 10-inch woofer.
Frequency Response
RP-1600SW has a frequency range of 14.5-175 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 RP-1600SW's min frequency of 15Hz.
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 RP-1600SW has a Bass Reflex type cabinet. 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. 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 RP-1600SW's and B&W DB4S's external dimensions. Klipsch RP-1600SW has external dimensions of 596.0 x 597.0 x 696.0mm ( 23-7/16inch x 23-1/2inch x 27-3/8inch ) 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 RP-1600SW is clearly the larger of the two speakers. Its body is 235mm wider, 221mm taller and 262mm deeper than B&W DB4S.
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 RP-1600SW is approximately 4155.1cm2 / 644.0inch2 and base area of the B&W DB4S is approximately 1571.1cm2 / 243.5inch2. The RP-1600SW requires 164% more surface area than the DB4S 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 Klipsch RP-1600SW weighs 50.00kg / 110lbs and the B&W DB4S weighs 26.05kg / 57.3lbs. This makes the RP-1600SW 92% heavier than the DB4S.
Here is a comparison of how RP-1600SW and DB4S's weights compare with the average, max and min weights in Powered Subwoofer class.
