Physical Specs

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 Audioengine A1-MR is approximately 192.6cm2 / 29.9inch2 and base area of the Klipsch R-41PM is approximately 356.2cm2 / 55.2inch2. The A1-MR requires 46% less surface area than the R-41PM which gives it a small advantage on placement in tight spaces.
Weight Comparison The weight of a loudspeaker can become an important factor if you need to move and reposition the unit often. Weight of a speaker can also "sometimes" be an indicator of the rigidity of the enclosure and the quality of the internal components used. The Audioengine A1-MR weighs 1.10kg / 2.4lbs and the Klipsch R-41PM weighs 3.70kg / 8.1lbs. This makes the R-41PM 236% heavier than the A1-MR.
