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.
Ultra Bookshelf can handle a max power of 150 watts RMS from the amp the whereas Reva 2 has a max power handling value of 80 watts RMS, 70 watts less than the Ultra Bookshelf.
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
Both Ultra Bookshelf and Reva 2 features dual binding post speaker terminals for bi-amping or bi-wiring.
Cabinet Type and Port Position
Ultra Bookshelf has a rear firing port whereas Reva 2 has a bottom firing ports. Wharfedale Reva 2's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to SVS Ultra Bookshelf with its rear-firing port.

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 SVS Ultra Bookshelf is approximately 612.6cm2 / 95.0inch2 and base area of the Wharfedale Reva 2 is approximately 655.3cm2 / 101.6inch2. The Ultra Bookshelf requires 7% 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 SVS Ultra Bookshelf weighs 8.64kg / 19lbs and the Wharfedale Reva 2 weighs 7.82kg / 17.2lbs. This makes the Ultra Bookshelf 10% heavier than the Reva 2.
