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 KEF Kube 12 MIE's and SVS SB-1000 Pro's external dimensions. KEF Kube 12 MIE has external dimensions of 410 x 393 x 410 mm ( 16.1 x 15.5 x 16.1 in) 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 ) .
KEF Kube 12 MIE is clearly the larger of the two speakers. Its body is 62mm wider, 67mm taller and 8mm 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 KEF Kube 12 MIE is approximately 1611.3cm2 / 249.8inch2 and base area of the SVS SB-1000 Pro is approximately 1330.6cm2 / 206.2inch2. The Kube 12 MIE requires 21% 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 KEF Kube 12 MIE weighs 18.60kg / 40.9lbs and the SVS SB-1000 Pro weighs 11.82kg / 26lbs. This makes the Kube 12 MIE 57% heavier than the SB-1000 Pro.
Here is a comparison of how Kube 12 MIE and SB-1000 Pro's weights compare with the average, max and min weights in Powered Subwoofer class.
