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.

Q150 can handle a max power of 100 watts RMS from the amp the whereas Reva 2 has a max power handling value of 80 watts RMS, 20 watts less than the Q150.

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

Reva 2 features Post posts which make bi-amping or bi-wiring possible. Q150 has a Post 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. In this section, we are going to compare KEF Q150's and Wharfedale Reva 2's external dimensions. KEF Q150 has external dimensions of 303.0 x 180.0 x 278.0mm ( 11.9 x 7.0 x 10.9inch) whereas Wharfedale Reva 2 has external dimensions of 358.0 x 201.0 x 326.0mm ( 14-1/16 x 7-7/8 x 12-13/16inch) .

Wharfedale Reva 2 is clearly the larger of the two speakers. Its body is 21mm wider, 55mm taller and 48mm deeper than KEF Q150.

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 KEF Q150 is approximately 500.4cm2 / 77.6inch2 and base area of the Wharfedale Reva 2 is approximately 655.3cm2 / 101.6inch2. The Q150 requires 24% less surface area than the Reva 2 which gives it a small advantage on placement in tight spaces.

Weight Comparison

The weight of a loudspeaker can become an important factor if you need to move and reposition the unit often. Weight of a speaker can also "sometimes" be an indicator of the rigidity of the enclosure and the quality of the internal components used. The KEF Q150 weighs 5.60kg / 12.3lbs and the Wharfedale Reva 2 weighs 7.82kg / 17.2lbs. This makes the Reva 2 40% heavier than the Q150.
