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 MartinLogan BalancedForce 210's and Klipsch RP-1400SW's external dimensions. MartinLogan BalancedForce 210 has external dimensions of 485.0 x 486.0 x 543.0mm ( 19-1/16inch x 19-1/8inch x 21-3/8inch ) whereas Klipsch RP-1400SW has external dimensions of 542.0 x 508.0 x 653.0mm ( 21-5/16inch x 20inch x 25-11/16inch ) .
Klipsch RP-1400SW is clearly the larger of the two speakers. Its body is 22mm wider, 57mm taller and 110mm deeper than MartinLogan BalancedForce 210.
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 MartinLogan BalancedForce 210 is approximately 2639.0cm2 / 409.0inch2 and base area of the Klipsch RP-1400SW is approximately 3317.2cm2 / 514.2inch2. The BalancedForce 210 requires 20% less surface area than the RP-1400SW which gives it a small advantage on placement in tight spaces.
