Frequency Response
PB-1000 has a frequency range of 19-270 Hz whereas Dynamo 600X has a frequency range of 27-200 Hz. With a minimum frequency of 19Hz, the PB-1000 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.

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 PB-1000's and MartinLogan 600X's external dimensions. SVS PB-1000 has external dimensions of 480.0 x 381.0 x 532.0mm ( 18-7/8 x 15 x 20-15/16inch) 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 PB-1000 is clearly the larger of the two speakers. Its body is 12mm wider, 65mm taller and 112mm deeper than MartinLogan 600X.

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 PB-1000 is approximately 2026.9cm2 / 314.2inch2 and base area of the MartinLogan 600X is approximately 1549.8cm2 / 240.2inch2. The PB-1000 requires 31% 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 PB-1000 weighs 20.91kg / 46lbs and the MartinLogan 600X weighs 15.91kg / 35lbs. This makes the PB-1000 31% heavier than the Dynamo 600X.
Here is a comparison of how PB-1000 and Dynamo 600X's weights compare with the average, max and min weights in Powered Subwoofer class.
