What size room are the Jamo C 93 II and Klipsch RP-600M 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:

C 93 II features a 1" Soft-Dome Tweeter and 1 x 6" Composite Woofer. On the other hand, the RP-600M features a 1" Tractrix Horn Tweeter and 1 x 6.5" Cerametallic Woofer with a Crossover frequency at 1500Hz.
Frequency Response
C 93 II has a frequency range of 45-24k Hz whereas RP-600M has a frequency range of 45-25k Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Bookshelf class in our database.
Low Frequency
Bookshelf 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 93 II is a 6 ohms speaker compared to the RP-600M which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. C 93 II sensitivity is rated at 86 dB and the RP-600M's is rated at 96 dB. This 8 dB difference makes the Klipsch RP-600M a more sensitive speaker compared to Jamo C 93 II, hence will play louder with the same amount of watts.
Sensitivity
Bookshelf 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 93 II can handle a max power of 120 watts RMS, whereas RP-600M has a max power handling value of 100 watts RMS, 20 watts less than the C 93 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-600M features Dual binding posts/bi-wire/bi-amp posts which make bi-amping or bi-wiring possible. C 93 II has a 5-way post which doesn't feature bi-amping/bi-wiring.
Klipsch RP-600M's Dual binding posts/bi-wire/bi-amp terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both C 93 II and RP-600M 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 93 II's and Klipsch RP-600M's external dimensions. Jamo C 93 II has external dimensions of 350.0 x 200.0 x 259.0mm (13.7 x 7.8 x 10.1inch) whereas Klipsch RP-600M has external dimensions of 399.0 x 202.0 x 301.0mm (15.7 x 7.9 x 11.8inch).
Klipsch RP-600M is clearly the larger of the two speakers. Its body is 2mm wider, 49mm taller and 42mm deeper than Jamo C 93 II.
Below you can see the front view size comparison of Jamo C 93 II and Klipsch RP-600M 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 93 II is approximately 518.0cm2 / 80.3inch2 and base area of the Klipsch RP-600M is approximately 608.0cm2 / 94.2inch2. The C 93 II requires 15% less surface area than the RP-600M which gives it a small advantage on placement in tight spaces.
Here is another comparison that shows both speakers on a BDI Octave Media Cabinet, next to a standard size amplifier and turntable in scale:

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 93 II weighs 6.40kg / 14.1lbs and the Klipsch RP-600M weighs 7.30kg / 16.1lbs. This makes the RP-600M 14% heavier than the C 93 II.

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 (45Hz vs 45Hz). |
| Amplifier needs | B | Klipsch RP-600M is more sensitive (96dB vs 88dB), so it goes louder on the same amplifier. |
| Amplifier match | B | Klipsch RP-600M is the easier load at 8 ohms. |
| Headroom | evenly matched | Similar power handling (120W vs 100W). |
| Size | depends | Jamo C 93 II is easier to place; Klipsch RP-600M is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | B | Klipsch RP-600M: bi-amping. Klipsch RP-600M sits in a wider range (17 models), so a matched surround system is easier later. |
| Price | B | Klipsch RP-600M is cheaper - $459 against $574, about 20% less. |
A Jamo C 93 II B Klipsch RP-600M
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-600M is the easier recommendation: it leads on most of the measured areas and costs less. Take Jamo C 93 II if its size, looks or fit in your room suit you better. Match it to your room: we rate Jamo C 93 II the better fit for a mid-size room and a large room, and Klipsch RP-600M for near-field listening and a small room. If your amplifier is modest, vintage or valve-based, Klipsch RP-600M 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.
