In this review, we will be comparing CWM362 and IW-DC51-W, two Passive In-wall speakers from Bowers Wilkins and ELAC. Let's have a brief look at the main features
of B&W CWM362 and ELAC IW-DC51-W first before getting into our more
detailed comparison.
What size room are the B&W CWM362 and ELAC IW-DC51-W 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:

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 120 watts RMS from the amp the whereas CWM362 has a max power handling value of 80 watts RMS , 40 watts less than the IW-DC51-W.
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 IW-DC51-W has a Spring post type posts. None of these speakers feature bi-amping/bi-wiring.
