Drivers
One of the fundamental differences between these two speakers is that CP-WT150 is a 2-way design whereas the B28W 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.

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 B28W 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 B28W's is rated at 0 dB. This 85 dB difference makes the Monitor Audio CP-WT150 a more sensitive speaker compared to Revel B28W, 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 350 watts RMS from the amp the whereas CP-WT150 has a max power handling value of 50 watts RMS , 300 watts less than the B28W.
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 B28W 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.
