In this review, we will be comparing R-820F and RP-280F, two Passive Floor-standing speakers by Klipsch. Let's have a brief look at the main features of Klipsch R-820F and Klipsch RP-280F first before getting into our more detailed comparison.
In the following sections, we will get into details in order to better understand how Klipsch R-820F and Klipsch RP-280F compares and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Both R-820F and RP-280F are 2-way speakers. R-820F features a 1" Tweeter and 2 x 8" Copper-spun IMG Woofer . On the other hand, RP-280F features a 1" Tractrix Horn Tweeter and 2 x 8" Cerametallic Woofer .
R-820F has a frequency range of 35-21k Hz whereas RP-280F has a frequency range of 32-25k Hz. With a minimum frequency of 35Hz, the R-820F can go slightly deeper then the RP-280F's min frequency of 32Hz.
Below graphs depict how these two speakers compare with the max, min and average values of the Min and Max Frequencies of other speakers under Floor-standing class in our database.
Impedance and Sensitivity
R-820F and RP-280F has the same Impedance of 8 ohms but where they differ is the sensitivity levels. R-820F sensitivity is rated at 97 dB and RP-280F's is at 98 dB. This 1 dB difference makes Klipsch RP-280F a more sensitive speaker compared to Klipsch R-820F, hence will play louder with the same amount of watts.
is the range of input power in watts RMS that a loudspeaker is designed to handle. While using an amplifier within this range ensures the nominal performance , inputting a power that is higher than the max wattage can result in a damaged speaker.
R-820F and RP-280F has the same power range of up to 150 watts.
Keep in mind that higher max power handling value doesn't necesssarily make that a louder speaker compared to a lower max handling speaker. Loudness or the sound level is also impacted by parameters such as Impededance, sensitivity and system efficiencies.
Input Type and Bi-Amping / Bi-Wiring
RP-280F features Binding post posts which makes bi-amping or bi-wiring possible. R-820F has a Post which doesn't feature bi-amping/bi-wiring.
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-820F's and Klipsch RP-280F's external dimensions. Klipsch R-820F has external dimensions of 1096.0 x 277.0 x 426.0mm ( 43-1/8 x 10-7/8 x 16-3/4inch) whereas Klipsch RP-280F has external dimensions of 1094.0 x 269.0 x 442.0mm ( 43-1/16 x 10-9/16 x 17-3/8inch) .
Klipsch RP-280F is 8mm narrower and 2mm shorter than Klipsch R-820F but it is also 16mm 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 Klipsch R-820F is approximately 1180.0cm2 / 182.9inch2 and base area of the Klipsch RP-280F is approximately 1189.0cm2 / 184.3inch2. The R-820F requires 1% less surface area than the RP-280F which gives it a small advantage on placement in tight spaces.
