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.
EVO4.3 can handle a max power of 200 watts RMS from the amp the whereas EVO4.3 has a max power handling value of 150 watts RMS , 50 watts less than the BP-9020.
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
EVO4.3 features Binding post posts which make bi-amping or bi-wiring possible. BP-9020 has a 5-Way post, RCA which doesn't 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.

Wharfedale EVO4.3 has external dimensions of 877.0 x 235.0 x 337.0mm ( 34-1/2 x 9-1/4 x 13-1/4inch) whereas Definitive BP-9020 has external dimensions of 904.0 x 281.0 x 351.0mm ( 35-9/16 x 11-1/16 x 13-13/16inch) .
Definitive BP-9020 is clearly the larger of the two speakers. Its body is 46mm wider, 27mm taller and 14mm deeper than Wharfedale EVO4.3.
Base Surface Area Comparison
Base surface area of a loudspeaker may become a determining factor when the space in your room or desk is limited.
The base surface area of the Wharfedale EVO4.3 is approximately 792.0cm2 / 122.8inch2 and base area of the Definitive BP-9020 is approximately 986.3cm2 / 152.9inch2. The EVO4.3 requires 20% less surface area than the BP-9020 which gives it a small advantage on placement in tight spaces.
