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
CP-WT150 is a 6 ohms speaker compared to the W150-LCR which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. CP-WT150 sensitivity is rated at 85 dB and the W150-LCR's is rated at 88 dB. This 3 dB difference makes the Monitor Audio W150-LCR a more sensitive speaker compared to Monitor Audio CP-WT150, 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.
CP-WT150 can handle a max power of 100 watts RMS from the amp the whereas CP-WT150 has a max power handling value of 50 watts RMS , 50 watts less than the W150-LCR.
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
CP-WT150 features Spring post type posts and W150-LCR has a Spring post type posts. None of these speakers feature bi-amping/bi-wiring.
Physical Specs
