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
CWM362 and 65 RT have the same Impedance of 8 ohms but where they differ is the sensitivity levels. CWM362 sensitivity is rated at 89 dB and the 65 RT's is at 90 dB. This 1 dB difference makes the Polk Audio 65 RT a more sensitive speaker compared to B&W CWM362, 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.
CWM362 can handle a max power of 125 watts RMS from the amp the whereas CWM362 has a max power handling value of 80 watts RMS , 45 watts less than the 65 RT.
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
CWM362 features Spring post type posts and 65 RT has a Spring post type posts. None of these speakers feature bi-amping/bi-wiring.
