Drivers
One of the fundamental differences between these two speakers is that Kendall is a 3-way design whereas the RP-6000F 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.

Kendall features a 1" anodized aluminum Tweeter, a 5.25" Midrange and 2 x 6.5" Woven Kevlar Woofer. On the other hand, the RP-6000F features a 1" Tractrix Horn Tweeter and 2 x 6.5" Cerametallic Woofer.
Frequency Response
Kendall has a frequency range of 25-23k Hz whereas RP-6000F has a frequency range of 34-25k Hz. With a minimum frequency of 25Hz, the Kendall can go significantly deeper on the low side and provide stronger bass compared to the RP-6000F's min frequency of 34Hz.
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
Kendall and RP-6000F have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Kendall sensitivity is rated at 96 dB and the RP-6000F's is at 97 dB. This 1 dB difference makes the Klipsch RP-6000F a more sensitive speaker compared to KLH Kendall, 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.
Kendall can handle a max power of 250 watts RMS, whereas RP-6000F has a max power handling value of 125 watts RMS, 125 watts less than the Kendall.
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.

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
Both Kendall and RP-6000F features dual binding post speaker terminals for bi-amping or 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 KLH Kendall's and Klipsch RP-6000F's external dimensions. KLH Kendall has external dimensions of 1021.0 x 212.0 x 380.0mm (40-3/16 x 8-5/16 x 14-15/16inch) whereas Klipsch RP-6000F has external dimensions of 1010.0 x 237.0 x 432.0mm (39-3/4 x 9-5/16 x 17inch).
KLH Kendall is 25mm narrower and 52mm less deeper than Klipsch RP-6000F but it is also 11mm taller.
Below you can see the front view size comparison of KLH Kendall and Klipsch RP-6000F 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 KLH Kendall is approximately 805.6cm2 / 124.9inch2 and base area of the Klipsch RP-6000F is approximately 1023.8cm2 / 158.7inch2. The Kendall requires 21% less surface area than the RP-6000F 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 KLH Kendall weighs 22.14kg / 48.7lbs and the Klipsch RP-6000F weighs 22.27kg / 49lbs. This makes the RP-6000F 1% heavier than the Kendall.

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 | A | KLH Kendall digs deeper - 25Hz against 34Hz. A subwoofer would even that out. |
| Amplifier needs | evenly matched | Similar sensitivity (96dB vs 97dB) - both want much the same power. |
| Headroom | A | KLH Kendall takes more power (250W vs 125W) - more in hand in a big room. |
| Size | depends | KLH Kendall is easier to place; Klipsch RP-6000F is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | depends | KLH Kendall: bi-amping; Klipsch RP-6000F: bi-amping. Klipsch RP-6000F sits in a wider range (17 models), so a matched surround system is easier later. |
| Price | evenly matched | Much the same money ($1,500 vs $1,378 a pair). |
A KLH Kendall B Klipsch RP-6000F
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?
KLH Kendall has the edge on paper, though the margin is not large. The rows marked "depends" may matter more to you than the score does. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 34Hz anyway, so judge these on the other rows instead.
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.
