CS140 features a 1" Hard-Dome Tweeter and 1 x 4" Metal Matrix Polymer Woofer . On the other hand, the Stage 260W features a 1" Horn-Loaded Tweeter and 1 x 6.5" Polycellulose Woofer .
Frequency Response
CS140 has a frequency range of 75-30kHz whereas Stage 260W has a frequency range of 50-25kHz. With a minimum frequency of 50Hz, the Stage 260W can go significantly deeper on the low side and provide stronger bass compared to the CS140's min frequency of 75Hz.
Below graphs depict how these two speakers compare with the max, min and average values of the Min and Max Frequencies of other speakers in the In-wall class in our database.

High Frequency
In-wall Speakers
None of these speakers achieves full range experience which is commonly agreed as 20Hz-20kHz. In order to achieve lower lows / deeper bass, we recommend you pair these with a subwoofer. 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 Stage 260W 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 Stage 260W's is rated at 87 dB. This 2 dB difference makes the JBL Stage 260W a more sensitive speaker compared to Monitor Audio CS140, hence will play louder with the same amount of watts.

Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. While using an amplifier within this range ensures the nominal performance , inputting a power that is higher than the max wattage can result in a damaged speaker.
CS140 can handle a max power of 100 watts RMS from the amp the whereas CS140 has a max power handling value of 50 watts RMS , 50 watts less than the Stage 260W.
Keep in mind that a higher max power handling value doesn't necessarily make that a louder speaker
compared to a lower max handling speaker. Loudness or the sound level is also impacted by parameters
such as Impedance, sensitivity and system efficiencies.
Input Type and Bi-Amping / Bi-Wiring
CS140 features Spring clip type posts and Stage 260W has a Spring clip type posts. None of these speakers feature bi-amping/bi-wiring.
Physical Specs
Size of a speaker can sometimes become an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare Monitor Audio CS140's and JBL Stage 260W's external dimensions. 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 JBL Stage 260W has external dimensions of 312.0 x 185.0 x 91.0mm ( 12.2500-inch x 7.2500-inch x 3.5625-inch) .
Monitor Audio CS140 is 35mm narrower and 162mm shorter than JBL Stage 260W but it is also 10mm deeper.
