In this review, we will be comparing Depth 212 and ASW610, two Powered Subwoofer speakers from MartinLogan 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 MartinLogan Depth 212 and B&W ASW610 first before getting into our more detailed comparison.
In the following sections, we will get into details in order to better understand how the MartinLogan Depth 212 and B&W ASW610 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.MartinLogan Depth 212 and B&W ASW610 have a totally different setup: the MartinLogan Depth 212 features 2 x 12-inch drivers whereas the ASW610 features 1 x 10-inch drivers.
Frequency Response
Depth 212 has a frequency range of 18-120 Hz whereas ASW610 has a frequency range of 27-140 Hz. With a minimum frequency of 18Hz, the Depth 212 can go significantly deeper on the low side and provide stronger bass compared to the ASW610's min frequency of 27Hz.
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 MartinLogan Depth 212 and B&W ASW610 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 MartinLogan Depth 212's and B&W ASW610's external dimensions. MartinLogan Depth 212 has external dimensions of 533.0 x 503.0 x 518.0mm ( 21 x 19-13/16 x 20-3/8inch) whereas B&W ASW610 has external dimensions of 321.0 x 312.0 x 394.0mm ( 12-5/8 x 12-1/4 x 15-1/2inch) .
MartinLogan Depth 212 is clearly the larger of the two speakers. Its body is 191mm wider, 212mm taller and 124mm deeper than B&W ASW610.
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 MartinLogan Depth 212 is approximately 2605.5cm2 / 403.9inch2 and base area of the B&W ASW610 is approximately 1229.3cm2 / 190.5inch2. The Depth 212 requires 112% more surface area than the ASW610 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 MartinLogan Depth 212 weighs 57.60kg / 126.7lbs and the B&W ASW610 weighs 12.55kg / 27.6lbs. This makes the Depth 212 359% heavier than the ASW610.
Here is a comparison of how Depth 212 and ASW610's weights compare with the average, max and min weights in Powered Subwoofer class.
