In this review, we will be comparing Sub 3 and DB4S, two Powered Subwoofer speakers from Dynaudio 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 Dynaudio Sub 3 and B&W DB4S 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.Both Dynaudio Sub 3and B&W DB4S have a single woofer setup however the Dynaudio Sub 3's woofer is 9.5-inch whereas the B&W DB4S features a 10-inch woofer.
Frequency Response
Sub 3 has a frequency range of 22-175 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 Sub 3's min frequency of 22Hz.
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 Dynaudio Sub 3 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
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 Dynaudio Sub 3's and B&W DB4S's external dimensions. Dynaudio Sub 3 has external dimensions of 277.0 x 269.0 x 366.0mm (10-7/8 x 10-9/16 x 14-3/8inch) 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).
B&W DB4S is clearly the larger of the two speakers. Its body is 93mm wider, 98mm taller and 68mm deeper than Dynaudio Sub 3.
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 Dynaudio Sub 3 is approximately 984.5cm2 / 152.6inch2 and base area of the B&W DB4S is approximately 1571.1cm2 / 243.5inch2. The Sub 3 requires 37% 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 Dynaudio Sub 3 weighs 10.50kg / 23.1lbs and the B&W DB4S weighs 26.05kg / 57.3lbs. This makes the DB4S 148% heavier than the Sub 3.
Here is a comparison of how Sub 3 and DB4S's weights compare with the average, max and min weights in Powered Subwoofer class.
