Physical Specs
Size of a speaker can sometimes become an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare Fluance DB10's and Klipsch R-121SW's external dimensions. Fluance DB10 has external dimensions of 406.0 x 302.0 x 399.0mm ( 16 x 11-7/8 x 15-11/16inch) whereas Klipsch R-121SW has external dimensions of 423.0 x 407.0 x 532.0mm ( 16-5/8inch x 16inch x 20-15/16inch ) .
Klipsch R-121SW is clearly the larger of the two speakers. Its body is 105mm wider, 17mm taller and 133mm deeper than Fluance DB10.
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 Fluance DB10 is approximately 1205.0cm2 / 186.8inch2 and base area of the Klipsch R-121SW is approximately 2165.2cm2 / 335.6inch2. The DB10 requires 44% less surface area than the R-121SW 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 Fluance DB10 weighs 11.20kg / 24.6lbs and the Klipsch R-121SW weighs 16.00kg / 35.2lbs. This makes the R-121SW 43% heavier than the DB10.
Here is a comparison of how DB10 and R-121SW's weights compare with the average, max and min weights in Powered Subwoofer class.
