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 Ai61 and R-15PM 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 Fluance Ai61's and Klipsch R-15PM's external dimensions. Fluance Ai61 has external dimensions of 33.3 x 19.8 x 23.4 cm ( 13.1 x 7.8 x 9.2 inches) whereas Klipsch R-15PM has external dimensions of 317.5 x 177.8 x 250.8mm ( 12.5 x 7 x 9.875inch) .
Klipsch R-15PM is 20.2mm narrower and 15.5mm shorter than Fluance Ai61 but it is also 16.8mm deeper.
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 Fluance Ai61 is approximately 463.0cm2 / 71.8inch2 and base area of the Klipsch R-15PM is approximately 445.9cm2 / 69.1inch2. The Ai61 requires 4% more surface area than the R-15PM which gives it a small disadvantage on placement in tight spaces.
