Physical Specs
The size of a speaker can sometimes be 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 15 MIE's and SVS SB-1000 Pro's external dimensions. KEF Kube 15 MIE has external dimensions of 519 x 500 x 515 mm (20.4 x 19.7 x 20.3 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 15 MIE is clearly the larger of the two speakers. Its body is 169mm wider, 176mm taller and 113mm 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 15 MIE is approximately 2575.0cm2 / 399.1inch2 and base area of the SVS SB-1000 Pro is approximately 1330.6cm2 / 206.2inch2. The Kube 15 MIE requires 94% 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 15 MIE weighs 27.50kg / 60.5lbs and the SVS SB-1000 Pro weighs 11.82kg / 26lbs. This makes the Kube 15 MIE 133% heavier than the SB-1000 Pro.
