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 ELAC Varro RS700-SB is approximately 1755.6cm2 / 272.1inch2 and base area of the ELAC Varro RS500-SB is approximately 1400.7cm2 / 217.1inch2. The Varro RS700-SB requires 25% more surface area than the Varro RS500-SB which gives it a small disadvantage on placement in tight spaces.
