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 215's and SVS SB-1000 Pro's external dimensions. MartinLogan Depth 215 has external dimensions of 572.0 x 580.0 x 595.0mm ( 22-1/2 x 22-13/16 x 23-7/16inch) whereas SVS SB-1000 Pro has external dimensions of 343.0 x 331.0 x 402.0mm ( 13-1/2inch x 13inch x 15-13/16inch ) .
MartinLogan Depth 215 is clearly the larger of the two speakers. Its body is 249mm wider, 229mm taller and 193mm deeper than SVS SB-1000 Pro.
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 215 is approximately 3451.0cm2 / 534.9inch2 and base area of the SVS SB-1000 Pro is approximately 1330.6cm2 / 206.2inch2. The Depth 215 requires 159% more surface area than the SB-1000 Pro 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 215 weighs 78.50kg / 172.7lbs and the SVS SB-1000 Pro weighs 11.82kg / 26lbs. This makes the Depth 215 564% heavier than the SB-1000 Pro.
Here is a comparison of how Depth 215 and SB-1000 Pro's weights compare with the average, max and min weights in Powered Subwoofer class.
