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 SVS PB-4000 is approximately 3970.0cm2 / 615.4inch2. The PB-1000 requires 49% less surface area than the PB-4000 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 SVS PB-1000 weighs 20.91kg / 46lbs and the SVS PB-4000 weighs 69.64kg / 153.2lbs. This makes the PB-4000 233% heavier than the PB-1000.
