In this review, we will be comparing SB-2000 and Dynamo 600X, two Powered Subwoofer speakers from SVS and MartinLogan. 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 SVS SB-2000 and MartinLogan 600X first before getting into our more detailed comparison.
In the following sections, we will get into details in order to better understand how the SVS SB-2000 and MartinLogan 600X 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.Both SVS SB-2000and MartinLogan 600X have a single woofer setup however the SVS SB-2000's woofer is 12-inch whereas the MartinLogan 600X features a 10-inch woofer.
Frequency Response
SB-2000 has a frequency range of 19-220 Hz whereas Dynamo 600X has a frequency range of 27-200 Hz. With a minimum frequency of 19Hz, the SB-2000 can go significantly deeper on the low side and provide stronger bass compared to the Dynamo 600X'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
The SVS SB-2000 has a Acoustic Suspension type cabinet. 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. On the other hand the MartinLogan 600X have Bass reflex type enclosure.
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 SVS SB-2000's and MartinLogan 600X's external dimensions. SVS SB-2000 has external dimensions of 372.0 x 362.0 x 478.0mm ( 14-5/8 x 14-1/4 x 18-13/16inch) whereas MartinLogan 600X has external dimensions of 415.0 x 369.0 x 420.0mm ( 16-5/16 x 14-1/2 x 16-1/2inch) .
SVS SB-2000 is 7mm narrower and 43mm shorter than MartinLogan 600X but it is also 58mm deeper.

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 SVS SB-2000 is approximately 1730.4cm2 / 268.2inch2 and base area of the MartinLogan 600X is approximately 1549.8cm2 / 240.2inch2. The SB-2000 requires 12% more surface area than the Dynamo 600X 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 SVS SB-2000 weighs 15.82kg / 34.8lbs and the MartinLogan 600X weighs 15.91kg / 35lbs. This makes the Dynamo 600X 1% heavier than the SB-2000.
Here is a comparison of how SB-2000 and Dynamo 600X's weights compare with the average, max and min weights in Powered Subwoofer class.
