In this review, we will be comparing SUB80P and DB4S, two Powered Subwoofer speakers from JBL 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 JBL SUB80P 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 JBL SUB80P 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.

The efficiency of a subwoofer is directly proportional to the total radiating are squared hence the woofer quantity and diameter.Both JBL SUB80Pand B&W DB4S have a single woofer setup however the JBL SUB80P's woofer is 8-inch whereas the B&W DB4S features a 10-inch woofer.
Frequency Response
SUB80P has a frequency range of 45-200 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 SUB80P's min frequency of 45Hz.
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 JBL SUB80P and B&W DB4S 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
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 JBL SUB80P's and B&W DB4S's external dimensions. JBL SUB80P has external dimensions of 353.0 x 267.0 x 267.0mm ( 13-7/8 x 10-1/2 x 10-1/2inch) 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) .
B&W DB4S is clearly the larger of the two speakers. Its body is 95mm wider, 22mm taller and 167mm deeper than JBL SUB80P.
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 JBL SUB80P is approximately 712.9cm2 / 110.5inch2 and base area of the B&W DB4S is approximately 1571.1cm2 / 243.5inch2. The SUB80P requires 55% 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 JBL SUB80P weighs 9.00kg / 19.8lbs and the B&W DB4S weighs 26.05kg / 57.3lbs. This makes the DB4S 189% heavier than the SUB80P.
Here is a comparison of how SUB80P and DB4S's weights compare with the average, max and min weights in Powered Subwoofer class.
