None of these speakers achieves full range experience which is commonly agreed as 20Hz-20kHz. In order to achieve lower lows / deeper bass, we recommend you pair these with a subwoofer. Visit our Powered Subwoofers section to find out more about the available options.
Cabinet Type and Port Position
Both R-15PM and HD6 have rear firing ports. Rear ported speakers generally need more room between the backside of the speaker and the wall compared to sealed and front/bottom ported speakers. Placing the speakers too close to the walls may cause the bass to sound boomy.
If you are limited in space and can't get the speakers away from the backwall, check our Speakers with Front Firing Ports page.
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 Klipsch R-15PM's and Audioengine HD6's external dimensions. Klipsch R-15PM has external dimensions of 317.5 x 177.8 x 250.8mm ( 12.5 x 7 x 9.875inch) whereas Audioengine HD6 has external dimensions of 314.3 x 182.6 x 317.5mm ( 12.375 x 7.1875 x 12.5inch) .
Klipsch R-15PM is 4.8mm narrower and 66.7mm less deeper than Audioengine HD6 but it is also 3.2mm taller.
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 Klipsch R-15PM is approximately 445.9cm2 / 69.1inch2 and base area of the Audioengine HD6 is approximately 579.8cm2 / 89.9inch2. The R-15PM requires 23% less surface area than the HD6 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 Klipsch R-15PM weighs 4.67kg / 10.3lbs and the Audioengine HD6 weighs 5.50kg / 12.1lbs. This makes the HD6 18% heavier than the R-15PM.
Here is a comparison of how R-15PM and HD6's weights compare with the average, max and min weights in Powered Bookshelf class.
