In this review, we will be comparing AK6 and R-620F, two Passive Floor-standing speakers by Klipsch Let's have a brief look at the main features
of Klipsch Klipschorn AK6 and Klipsch R-620F first before getting into our more
detailed comparison.
In the following sections, we will get into more detail in order to better understand how the Klipsch Klipschorn AK6 and Klipsch R-620F compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Drivers
One of the fundamental differences between these two speakers is that AK6 is a 3-way design whereas the R-620F is a 2-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker.

AK6 features a 1" polyimide diaphragm compression Tractrix horn Tweeter , a 2" Midrange and 1 x 15" fiber-composite with a trihedral exponential folded horn 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
AK6 has a frequency range of 33-20k Hz whereas R-620F has a frequency range of 38-21k Hz. With a minimum frequency of 33Hz, the AK6 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
AK6 and R-620F have the same Impedance of 8 ohms but where they differ is the sensitivity levels. AK6 sensitivity is rated at 105 dB and the R-620F's is at 96 dB. This 9 dB difference makes the Klipsch Klipschorn AK6 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.
AK6 and R-620F has the same power range of up to 100 watts.
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
AK6 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.
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 Klipschorn AK6's and Klipsch R-620F's external dimensions. Klipsch Klipschorn AK6 has external dimensions of 1347.0 x 794.0 x 718.0mm ( 53 x 31-1/4 x 28-1/4inch) 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 Klipschorn AK6 is clearly the larger of the two speakers. Its body is 555mm wider, 326mm taller and 349mm deeper than Klipsch R-620F.
Below you can see the front view size comparison of Klipsch Klipschorn AK6 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 Klipsch Klipschorn AK6 is approximately 5700.9cm2 / 883.6inch2 and base area of the Klipsch R-620F is approximately 881.9cm2 / 136.7inch2. The AK6 requires 546% more surface area than the R-620F which gives it a small disadvantage 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 Klipschorn AK6 weighs 100.00kg / 220lbs and the Klipsch R-620F weighs 18.64kg / 41lbs. This makes the AK6 436% heavier than the R-620F.
Here is a comparison of how AK6 and R-620F's weights compare with the average, max and min weights in Passive Floor-standing class.
