SVS SB-1000 Pro has external dimensions of 343.0 x 331.0 x 402.0mm ( 13-1/2inch x 13inch x 15-13/16inch ) whereas Polk PSW125 has external dimensions of 424.0 x 413.0 x 520.0mm ( 16-11/16 x 16-1/4 x 20-7/16inch) .
Polk PSW125 is clearly the larger of the two speakers. Its body is 82mm wider, 81mm taller and 118mm deeper than SVS SB-1000 Pro.

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 SB-1000 Pro is approximately 1330.6cm2 / 206.2inch2 and base area of the Polk PSW125 is approximately 2147.6cm2 / 332.9inch2. The SB-1000 Pro requires 38% less surface area than the PSW125 which gives it a small advantage on placement in tight spaces.
