What size room are the Monitor Audio CP-WT380IDC and Monitor Audio IWS-10 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:

Average Floor Height: 9" / 2.7m. Typical room sizes differ from country to country, and the actual
listening experience changes depending on floor height, room shape, surface materials, listening
position, speaker locations, etc.)
The sections below take each area in turn: drivers, frequency response, physical size and what you get in the box.
Drivers
One of the fundamental differences between these two speakers is that CP-WT380IDC is a 3-way design whereas the IWS-10 is a 1-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker.

CP-WT380IDC features a 1" Hard-Dome Tweeter, a 4" Midrange and 1 x 8" C-CAM Woofer. On the other hand, the IWS-10 features a " Tweeter and 1 x 10" C-CAM/RDT Woofer.
Frequency Response
CP-WT380IDC has a frequency range of 50-30kHz whereas IWS-10 has a frequency range of 28-120Hz. With a minimum frequency of 28Hz, the IWS-10 can go significantly deeper on the low side and provide stronger bass compared to the CP-WT380IDC's min frequency of 50Hz.
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
CP-WT380IDC is a 6 ohms speaker compared to the IWS-10 which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. CP-WT380IDC sensitivity is rated at 89 dB and the IWS-10's is rated at 86 dB. This 3 dB difference makes the Monitor Audio CP-WT380IDC a more sensitive speaker compared to Monitor Audio IWS-10, 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.
IWS-10 can handle a max power of 150 watts RMS, whereas CP-WT380IDC has a max power handling value of 120 watts RMS, 30 watts less than the IWS-10.
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.
