On the other hand the Klipsch R-100SW have Bass reflex type enclosure.
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 Monitor Audio Radius 380's and Klipsch R-100SW's external dimensions. Monitor Audio Radius 380 has external dimensions of 308.0 x 291.0 x 345.0mm ( 12-1/8 x 11-7/16 x 13-9/16inch) whereas Klipsch R-100SW has external dimensions of 372.0 x 320.0 x 459.0mm ( 14-5/8 x 12-9/16 x 18-1/16inch) .
Klipsch R-100SW is clearly the larger of the two speakers. Its body is 29mm wider, 64mm taller and 114mm deeper than Monitor Audio Radius 380.
Below you can see the front view size comparison of Monitor Audio Radius 380 and Klipsch R-100SW in scale.

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 Monitor Audio Radius 380 is approximately 1004.0cm2 / 155.6inch2 and base area of the Klipsch R-100SW is approximately 1468.8cm2 / 227.7inch2. The Radius 380 requires 32% less surface area than the R-100SW 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 Monitor Audio Radius 380 weighs 10.18kg / 22.4lbs and the Klipsch R-100SW weighs 10.91kg / 24lbs. This makes the R-100SW 7% heavier than the Radius 380.
