Drivers
One of the fundamental differences between these two speakers is that CP-WT150 is a 2-way design whereas the IWSub 1010 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-WT150 features a 1" Hard-Dome Tweeter and 1 x 5" Poly Woofer . On the other hand, the IWSub 1010 features a " Tweeter and 1 x 10" Not given Woofer .
Frequency Response
CP-WT150 has a frequency range of 75-25kHz whereas IWSub 1010 has a frequency range of 16-200Hz. With a minimum frequency of 16Hz, the IWSub 1010 can go significantly deeper on the low side and provide stronger bass compared to the CP-WT150'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.

Impedance and Sensitivity
CP-WT150 is a 6 ohms speaker compared to the IWSub 1010 which has a nominal impedance of 4 ohms. Lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit especially when played at high volume levels, so make sure the amp you pair with the IWSub 1010 can provide this impedance level.
These two speakers also have different sensitivity levels. CP-WT150 sensitivity is rated at 85 dB and the IWSub 1010's is rated at 0 dB. This 85 dB difference makes the Monitor Audio CP-WT150 a more sensitive speaker compared to Definitive IWSub 1010, 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 275 watts RMS from the amp the whereas CP-WT150 has a max power handling value of 50 watts RMS , 225 watts less than the IWSub 1010.
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 IWSub 1010 has a Spring post 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.
