In this review, we will be comparing R-620F and RP-280F, two Passive Floor-standing speakers by Klipsch Let's have a brief look at the main features
of Klipsch R-620F and Klipsch RP-280F first before getting into our more
detailed comparison.
What size room are the Klipsch R-620F and Klipsch RP-280F speakers good for?
The size of the room in which you are planning to use these loudspeakers is an important decision factor. Here we have compared their suitability to various sizes of environments considering their size and max power parameters:
In the following sections, we will get into more detail in order to better understand how the Klipsch R-620F and Klipsch RP-280F compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

R-620F features a 1.0" Tweeter and 2 x 6.5" Copper-spun IMG Woofer with a Crossover frequency at 2000Hz. On the other hand, the RP-280F features a 1" Tractrix Horn Tweeter and 2 x 8" Cerametallic Woofer .
Frequency Response
R-620F has a frequency range of 38-21k Hz whereas RP-280F has a frequency range of 32-25k Hz. With a minimum frequency of 32Hz, the RP-280F can go significantly deeper on the low side and provide stronger bass compared to the R-620F's min frequency of 38Hz.
Below graphs depict how these two speakers compare with the max, min and average values of the Min and Max Frequencies of other speakers in the Floor-standing class in our database.

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.
Impedance and Sensitivity
R-620F and RP-280F have the same Impedance of 8 ohms but where they differ is the sensitivity levels. R-620F sensitivity is rated at 96 dB and the RP-280F's is at 98 dB. This 2 dB difference makes the Klipsch RP-280F a more sensitive speaker compared to Klipsch R-620F, hence will play louder with the same amount of watts.

Power Range
Power
range 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-620F can handle a max power of 150 watts RMS from the amp the whereas R-620F has a max power handling value of 100 watts RMS , 50 watts less than the RP-280F.
Keep in mind that a higher max power handling value doesn't necessarily make that a louder speaker
compared to a lower max handling speaker. Loudness or the sound level is also impacted by parameters
such as Impedance, sensitivity and system efficiencies.
Input Type and Bi-Amping / Bi-Wiring
RP-280F features Binding post posts which make bi-amping or bi-wiring possible. R-620F has a Post which doesn't feature bi-amping/bi-wiring.

Klipsch RP-280F's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both R-620F and RP-280F 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-620F's and Klipsch RP-280F's external dimensions. Klipsch R-620F has external dimensions of 1021.0 x 239.0 x 369.0mm ( 40-3/16 x 9-3/8 x 14-1/2inch) 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 clearly the larger of the two speakers. Its body is 30mm wider, 73mm taller and 73mm deeper than Klipsch R-620F.
Below you can see the front view size comparison of Klipsch R-620F and Klipsch RP-280F 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 Klipsch R-620F is approximately 881.9cm2 / 136.7inch2 and base area of the Klipsch RP-280F is approximately 1189.0cm2 / 184.3inch2. The R-620F requires 26% less surface area than the RP-280F 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-620F weighs 18.64kg / 41lbs and the Klipsch RP-280F weighs 28.41kg / 62.5lbs. This makes the RP-280F 52% heavier than the R-620F.
Here is a comparison of how R-620F and RP-280F's weights compare with the average, max and min weights in Passive Floor-standing class.
