In this review, we will be comparing KC62 and DB3D, two Powered Subwoofer speakers from KEF 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 KEF KC62 and B&W DB3D first before getting into our more detailed comparison.
In the following sections, we will get into details in order to better understand how the KEF KC62 and B&W DB3D 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 KEF KC62and B&W DB3D have a double woofer setup however the KEF KC62's woofer is 6.5-inch whereas the B&W DB3D features a 8-inch woofer.
Frequency Response
KC62 has a frequency range of 11-200 Hz whereas DB3D has a frequency range of 10-350Hz. With a minimum frequency of 10Hz, the DB3D can go slightly deeper then the KC62's min frequency of 11Hz.
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.

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 KEF KC62's and B&W DB3D's external dimensions. KEF KC62 has external dimensions of 245.0 x 258.0 x 281.0mm ( 9-5/8inch x 10-1/8inch x 11-1/16inch ) whereas B&W DB3D has external dimensions of ( ) .
KEF KC62 is clearly the larger of the two speakers. Its body is 258mm wider, 245mm taller and 281mm deeper than B&W DB3D.
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 KEF KC62 weighs 14.05kg / 30.9lbs and the B&W DB3D weighs 25.05kg / 55.1lbs. This makes the DB3D 78% heavier than the KC62.
Here is a comparison of how KC62 and DB3D's weights compare with the average, max and min weights in Powered Subwoofer class.
