What size room are the Jamo C 97 II and Klipsch RP-6000F 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:

Drivers
One of the fundamental differences between these two speakers is that C 97 II 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.

C 97 II features a 1" Tweeter, a 6" Midrange and 3 x 6" Composite Woofer. On the other hand, the RP-6000F features a 1" Tractrix Horn Tweeter and 2 x 6.5" Cerametallic Woofer.
Frequency Response
C 97 II has a frequency range of 32-24k Hz whereas RP-6000F has a frequency range of 34-25k Hz. With a minimum frequency of 32Hz, the C 97 II can go slightly deeper then 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
C 97 II is a 6 ohms speaker compared to the RP-6000F which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. C 97 II sensitivity is rated at 89 dB and the RP-6000F's is rated at 97 dB. This 8 dB difference makes the Klipsch RP-6000F a more sensitive speaker compared to Jamo C 97 II, 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.
C 97 II can handle a max power of 180 watts RMS, whereas RP-6000F has a max power handling value of 125 watts RMS, 55 watts less than the C 97 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
Both C 97 II and RP-6000F features dual binding post speaker terminals for bi-amping or bi-wiring.
Jamo C 97 II's Posts terminals allows Bi-amping or bi-wiring
Klipsch RP-6000F's Post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both C 97 II and RP-6000F 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 Jamo C 97 II's and Klipsch RP-6000F's external dimensions. Jamo C 97 II has external dimensions of 1070.0 x 248.0 x 402.0mm (42-1/8 x 9-3/4 x 15-13/16inch) 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).
Klipsch RP-6000F is 11mm narrower and 60mm shorter than Jamo C 97 II but it is also 30mm deeper.
Below you can see the front view size comparison of Jamo C 97 II 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 Jamo C 97 II is approximately 997.0cm2 / 154.5inch2 and base area of the Klipsch RP-6000F is approximately 1023.8cm2 / 158.7inch2. The C 97 II requires 3% 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 Jamo C 97 II weighs 24.55kg / 54lbs and the Klipsch RP-6000F weighs 22.27kg / 49lbs. This makes the C 97 II 10% heavier than the RP-6000F.
Here is a comparison of how C 97 II and RP-6000F'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 | evenly matched | Much the same reach (32Hz vs 34Hz). |
| Amplifier needs | B | Klipsch RP-6000F is more sensitive (97dB vs 89dB), so it goes louder on the same amplifier. |
| Amplifier match | B | Klipsch RP-6000F is the easier load at 8 ohms. |
| Headroom | A | Jamo C 97 II takes more power (180W vs 125W) - more in hand in a big room. |
| Size | depends | Similar cabinet size - neither is easier to fit. |
| Expandability | depends | Jamo C 97 II: 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 ($1,378 vs $1,378 a pair). |
A Jamo C 97 II 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?
Klipsch RP-6000F 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 your amplifier is modest, vintage or valve-based, Klipsch RP-6000F 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.
