What size room are the Klipsch RP-6000F II and Klipsch R-620F 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:

RP-6000F II features a 1" titanium Tractrix Horn Tweeter and 2 x 6.5" Cerametallic cone Woofer with a Crossover frequency at 1770 Hz. 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
RP-6000F II has a frequency range of 38-25k Hz whereas R-620F has a frequency range of 38-21k Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Floor-standing class in our database.
Low Frequency
Floor-standing Speakers
Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
RP-6000F II and R-620F have the same Impedance of 8 ohms and their sensitivity is also same at 96 dB.
Sensitivity
Floor-standing Speakers
Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
RP-6000F II can handle a max power of 125 watts RMS, whereas R-620F has a max power handling value of 100 watts RMS, 25 watts less than the RP-6000F II.
Note that higher power handling does not make a speaker louder: that depends mainly on
sensitivity and impedance. The calculator below shows how loud each of these actually plays
on a real amplifier.
Which plays louder on your amplifier?
Starting with a popular amplifier - change it to the one you own, or any you are
considering, and watch both numbers move.
Input Type and Bi-Amping / Bi-Wiring
RP-6000F II 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-6000F II's Binding post terminals allows Bi-amping or bi-wiring
Klipsch R-620F's Post terminals
Cabinet Type and Port Position
Both RP-6000F II and R-620F 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
The size of a speaker can sometimes be 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 RP-6000F II's and Klipsch R-620F's external dimensions. Klipsch RP-6000F II has external dimensions of 1007.0 x 237.0 x 431.0mm (39-5/8 x 9-5/16 x 16-15/16inch) 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 RP-6000F II is 2mm narrower and 14mm shorter than Klipsch R-620F but it is also 62mm deeper.
Below you can see the front view size comparison of Klipsch RP-6000F II 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 RP-6000F II is approximately 1021.5cm2 / 158.3inch2 and base area of the Klipsch R-620F is approximately 881.9cm2 / 136.7inch2. The RP-6000F II requires 16% 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 RP-6000F II weighs 22.50kg / 49.5lbs and the Klipsch R-620F weighs 18.64kg / 41lbs. This makes the RP-6000F II 21% heavier than the R-620F.
Here is a comparison of how RP-6000F II and R-620F's weights compare with the average, max and min weights in Passive Floor-standing class.

A generation apart: Klipsch RP-6000F II is the newer design, against a 2018 model. Newer is not automatically better, but the older one is more likely to be discounted or near run-out.
| Area | Better | Why |
|---|
| Bass | evenly matched | Much the same reach (38Hz vs 38Hz). |
| Amplifier needs | evenly matched | Similar sensitivity (96dB vs 96dB) - both want much the same power. |
| Headroom | A | Klipsch RP-6000F II takes more power (125W vs 100W) - more in hand in a big room. |
| Size | depends | Similar cabinet size - neither is easier to fit. |
| Expandability | A | Klipsch RP-6000F II: bi-amping and Atmos drivers. Klipsch RP-6000F II sits in a wider range (10 models), so a matched surround system is easier later. |
| Price | B | Klipsch R-620F is cheaper - $998 against $1,498, about 33% less. |
A Klipsch RP-6000F II B Klipsch R-620F
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
The usual trade-off: Klipsch RP-6000F II measures better, Klipsch R-620F costs about about 50% more% less. Whether that gap is worth the money is the call only you can make - and in a normal room it is often smaller than the numbers suggest. Match it to your room: we rate Klipsch RP-6000F II the better fit for a large room, and Klipsch R-620F for a small room. Think about the whole system, not just the speakers: the roughly $500 saved by taking the cheaper pair would buy a subwoofer or a better amplifier, and either usually does more for the sound than the difference between these two.
And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
