RTi A3 features a 1" silk polymer composite Dome Tweeter and 1 x 6.5" Polymer composite Woofer with a Crossover frequency at 2800Hz. On the other hand, the Reva 1 features a 1" woven textile Dome Tweeter and 1 x 4.5" Woven Glass Fiber Woofer .
Frequency Response
RTi A3 has a frequency range of 50-26k Hz whereas Reva 1 has a frequency range of 52-20k Hz. With a minimum frequency of 50Hz, the RTi A3 can go slightly deeper then the Reva 1's min frequency of 52Hz.
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 Bookshelf class in our database.

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
RTi A3 and Reva 1 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. RTi A3 sensitivity is rated at 89 dB and the Reva 1's is at 86 dB. This 3 dB difference makes the Polk RTi A3 a more sensitive speaker compared to Wharfedale Reva 1, 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.
RTi A3 can handle a max power of 150 watts RMS from the amp the whereas Reva 1 has a max power handling value of 60 watts RMS, 90 watts less than the RTi A3.
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 RTi A3 and Reva 1 features dual binding post speaker terminals for bi-amping or bi-wiring.
Cabinet Type and Port Position
RTi A3 has a back and front firing port whereas Reva 1 has a bottom firing ports.
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 Polk RTi A3's and Wharfedale Reva 1's external dimensions. Polk RTi A3 has external dimensions of 374.7 x 214.4 x 355.6mm ( 14.7 x 8.4 x 14.0inch) whereas Wharfedale Reva 1 has external dimensions of 318.0 x 174.0 x 285.0mm ( 12-1/2 x 6-13/16 x 11-3/16inch) .
Polk RTi A3 is clearly the larger of the two speakers. Its body is 40.4mm wider, 56.7mm taller and 70.6mm deeper than Wharfedale Reva 1.
Below you can see the front view size comparison of Polk RTi A3 and Wharfedale Reva 1 in scale.
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 Polk RTi A3 is approximately 762.4cm2 / 118.2inch2 and base area of the Wharfedale Reva 1 is approximately 495.9cm2 / 76.9inch2. The RTi A3 requires 54% more surface area than the Reva 1 which gives it a small disadvantage on placement in tight spaces.
Here is an another comparison that shows both speakers on a BDI Octave Media Cabinet, next to a standard size amplifier and turntable in scale:
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 Polk RTi A3 weighs 7.26kg / 16lbs and the Wharfedale Reva 1 weighs 5.64kg / 12.4lbs. This makes the RTi A3 29% heavier than the Reva 1.
Here is a comparison of how RTi A3 and Reva 1's weights compare with the average, max and min weights in Passive Bookshelf class.
