In this review, we will be comparing CW10 and DB4S, two Powered Subwoofer speakers from Monitor Audio 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.

Drivers
The efficiency of a subwoofer is directly proportional to the total radiating are squared hence the woofer quantity and diameter.Monitor Audio CW10and B&W DB4S have the same driver set up: Both subwoofers have 1 x 10" drivers.
Frequency Response
CW10 has a frequency range of 32-135 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 CW10'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.

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 Monitor Audio CW10's and B&W DB4S's external dimensions. Monitor Audio CW10 has external dimensions of 318.0 x 307.0 x 375.0mm ( 12-1/2 x 12-1/16 x 14-3/4inch) 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 55mm wider, 57mm taller and 59mm deeper than Monitor Audio CW10.
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 Monitor Audio CW10 is approximately 1151.3cm2 / 178.5inch2 and base area of the B&W DB4S is approximately 1571.1cm2 / 243.5inch2. The CW10 requires 27% 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 Monitor Audio CW10 weighs 12.61kg / 27.7lbs and the B&W DB4S weighs 26.05kg / 57.3lbs. This makes the DB4S 107% heavier than the CW10.
Here is a comparison of how CW10 and DB4S's weights compare with the average, max and min weights in Powered Subwoofer class.
