CS140 features a 1" Hard-Dome Tweeter and 1 x 4" Metal Matrix Polymer Woofer. On the other hand, the R-5502-W II features a 1" Horn-loaded Tweeter and 2 x 5.25" Cerametallic Woofer with a Crossover frequency at 2200 Hz.
Frequency Response
CS140 has a frequency range of 75-30kHz whereas R-5502-W II has a frequency range of 46-20kHz. With a minimum frequency of 46Hz, the R-5502-W II can go significantly deeper on the low side and provide stronger bass compared to the CS140's min frequency of 75Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the In-wall class in our database.
Low Frequency
In-wall 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
CS140 is a 6 ohms speaker compared to the R-5502-W II which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. CS140 sensitivity is rated at 85 dB and the R-5502-W II's is rated at 92 dB. This 7 dB difference makes the Klipsch R-5502-W II a more sensitive speaker compared to Monitor Audio CS140, hence will play louder with the same amount of watts.
Sensitivity
In-wall 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.
R-5502-W II can handle a max power of 75 watts RMS, whereas CS140 has a max power handling value of 50 watts RMS, 25 watts less than the R-5502-W 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
CS140 features Spring post type posts and R-5502-W II has a Spring post type posts. None of these speakers 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.

Monitor Audio CS140 has external dimensions of 150.0 x 150.0 x 101.0mm (5.8750-inch x 5.8750-inch x 3.9375-inch) whereas Klipsch R-5502-W II has external dimensions of 416.0 x 166.0 x 86.0mm (16.3750-inch x 6.5000-inch x 3.3750-inch).
Monitor Audio CS140 is 16mm narrower and 266mm shorter than Klipsch R-5502-W II but it is also 15mm deeper.

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 Monitor Audio CS140 weighs 1.18kg / 2.6lbs and the Klipsch R-5502-W II weighs 2.95kg / 6.5lbs. This makes the R-5502-W II 150% heavier than the CS140.
Here is a comparison of how CS140 and R-5502-W II's weights compare with the average, max and min weights in Passive In-wall 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 | Klipsch R-5502-W II digs deeper - 46Hz against 75Hz. |
| Amplifier needs | B | Klipsch R-5502-W II is more sensitive (92dB vs 85dB), so it goes louder on the same amplifier. |
| Amplifier match | B | Klipsch R-5502-W II is the easier load at 8 ohms. |
| Headroom | B | Klipsch R-5502-W II takes more power (75W vs 50W) - more in hand in a big room. |
| Size | depends | Monitor Audio CS140 is easier to place; Klipsch R-5502-W II is bigger, which usually goes with fuller bass. Your room decides. |
| Price | A | Monitor Audio CS140 is cheaper - $440 against $498, about 12% less. |
A Monitor Audio CS140 B Klipsch R-5502-W II
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 R-5502-W II leads across most of the measured areas for a fairly modest premium, which makes it the easier pick if the budget stretches. Monitor Audio CS140 is the one to take if it does not. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 75Hz anyway, which makes the cheaper Monitor Audio CS140 much easier to justify. In a large or open-plan room, Klipsch R-5502-W II has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, Monitor Audio CS140 is the easier speaker to get right.
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.
