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 GoldenEar ForceField 3 is approximately 1265.8cm2 / 196.2inch2 and base area of the MartinLogan 600X is approximately 1549.8cm2 / 240.2inch2. The ForceField 3 requires 18% less surface area than the Dynamo 600X 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 GoldenEar ForceField 3 weighs 11.82kg / 26lbs and the MartinLogan 600X weighs 15.91kg / 35lbs. This makes the Dynamo 600X 35% heavier than the ForceField 3.
