A180 features a 1" aluminum HDI (High Definition Imaging) waveguide Tweeter and 2 x 6.5" Polycellulose Woofer . On the other hand, the R-620F features a 1.0" Tweeter and 2 x 6.5" Copper-spun IMG Woofer with a Crossover frequency at 2000Hz.
Frequency Response
A180 has a frequency range of 40-40k Hz whereas R-620F has a frequency range of 38-21k Hz. With a minimum frequency of 38Hz, the R-620F can go slightly deeper then the A180's min frequency of 40Hz.
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.

High Frequency
Floor-standing Speakers
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
A180 is a 6 ohms speaker compared to the R-620F which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. A180 sensitivity is rated at 90 dB and the R-620F's is rated at 96 dB. This 6 dB difference makes the Klipsch R-620F a more sensitive speaker compared to JBL Stage A180, 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.
A180 can handle a max power of 225 watts RMS from the amp the whereas R-620F has a max power handling value of 100 watts RMS, 125 watts less than the A180.
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
A180 features 5-Way post posts which make bi-amping or bi-wiring possible. R-620F has a Post which doesn't feature bi-amping/bi-wiring.

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 JBL Stage A180's and Klipsch R-620F's external dimensions. JBL Stage A180 has external dimensions of 1045.0 x 305.0 x 369.0mm ( 41-1/8 x 12 x 14-1/2inch) whereas 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) .
Klipsch R-620F is 66mm narrower and 24mm shorter than JBL Stage A180 but they have the same thickness of 369.0mm.
Below you can see the front view size comparison of JBL Stage A180 and Klipsch R-620F 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 JBL Stage A180 is approximately 1125.5cm2 / 174.5inch2 and base area of the Klipsch R-620F is approximately 881.9cm2 / 136.7inch2. The A180 requires 28% more surface area than the R-620F which gives it a small disadvantage on placement in tight spaces.
