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-4000 is approximately 3970.0cm2 / 615.4inch2 and base area of the SVS PB-1000 Pro is approximately 1934.2cm2 / 299.8inch2. The PB-4000 requires 105% more surface area than the PB-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 SVS PB-4000 weighs 69.64kg / 153.2lbs and the SVS PB-1000 Pro weighs 19.30kg / 42.5lbs. This makes the PB-4000 261% heavier than the PB-1000 Pro.
