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 Concord features a 1" anodized aluminum Tweeter and 2 x 6.5" Kevlar Woofer.
Frequency Response
RP-6000F II has a frequency range of 38-25k Hz whereas Concord has a frequency range of 28-23k Hz. With a minimum frequency of 28Hz, the Concord can go significantly deeper on the low side and provide stronger bass compared to the RP-6000F II's min frequency of 38Hz.
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 Concord have the same Impedance of 8 ohms but where they differ is the sensitivity levels. RP-6000F II sensitivity is rated at 96 dB and the Concord's is at 94 dB. This 2 dB difference makes the Klipsch RP-6000F II a more sensitive speaker compared to KLH Concord, hence will play louder with the same amount of watts.
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.
Concord can handle a max power of 225 watts RMS, whereas RP-6000F II has a max power handling value of 125 watts RMS, 100 watts less than the Concord.
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. Concord has a 5-Way post which doesn't feature bi-amping/bi-wiring.

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 KLH Concord'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 KLH Concord has external dimensions of 1026.0 x 212.0 x 380.0mm (40-3/8 x 8-5/16 x 14-15/16inch).
KLH Concord is 25mm narrower and 51mm less deeper than Klipsch RP-6000F II but it is also 19mm taller.
Below you can see the front view size comparison of Klipsch RP-6000F II and KLH Concord 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 KLH Concord is approximately 805.6cm2 / 124.9inch2. The RP-6000F II requires 27% more surface area than the Concord 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 KLH Concord weighs 20.45kg / 45lbs. This makes the RP-6000F II 10% heavier than the Concord.
Here is a comparison of how RP-6000F II and Concord's weights compare with the average, max and min weights in Passive Floor-standing class.

No single best speaker here - they are built to different priorities, and the right one depends on your room, your amplifier and what you listen to.
| Area | Better | Why |
|---|
| Bass | B | KLH Concord digs deeper - 28Hz against 38Hz. |
| Amplifier needs | A | Klipsch RP-6000F II is more sensitive (96dB vs 94dB), so it goes louder on the same amplifier. |
| Headroom | B | KLH Concord takes more power (225W vs 125W) - 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. |
| Price | B | KLH Concord is cheaper - $1,000 against $1,498, about 33% less. |
A Klipsch RP-6000F II B KLH Concord
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?
Neither runs away with it - they trade advantages. Let the "depends" rows and your own room settle it. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 38Hz anyway, so judge these on the other rows instead. If your amplifier is modest, vintage or valve-based, Klipsch RP-6000F II is the safer partner - the other will want more current or more watts to sound its best.
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.
