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 8 MIE is approximately 908.3cm2 / 140.8inch2 and base area of the SVS PB-1000 is approximately 2026.9cm2 / 314.2inch2. The Kube 8 MIE requires 55% less surface area than the PB-1000 which gives it a small advantage 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 8 MIE weighs 9.40kg / 20.7lbs and the SVS PB-1000 weighs 20.91kg / 46lbs. This makes the PB-1000 122% heavier than the Kube 8 MIE.
