RTi A1 features a 1" silk polymer composite Dome Tweeter and 1 x 5.25" Polymer composite Woofer with a Crossover frequency at 1900Hz. 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 A1 has a frequency range of 60-26k Hz whereas Reva 1 has a frequency range of 52-20k Hz. With a minimum frequency of 52Hz, the Reva 1 can go significantly deeper on the low side and provide stronger bass compared to the RTi A1's min frequency of 60Hz.
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 A1 and Reva 1 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. RTi A1 sensitivity is rated at 89 dB and the Reva 1's is at 86 dB. This 3 dB difference makes the Polk RTi A1 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 A1 can handle a max power of 125 watts RMS from the amp the whereas Reva 1 has a max power handling value of 60 watts RMS, 65 watts less than the RTi A1.
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 A1 and Reva 1 features dual binding post speaker terminals for bi-amping or bi-wiring.
Cabinet Type and Port Position
RTi A1 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 A1's and Wharfedale Reva 1's external dimensions. Polk RTi A1 has external dimensions of 304.8 x 187.5 x 292.1mm ( 12.0 x 7.3 x 11.5inch) 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) .
Wharfedale Reva 1 is 13.5mm narrower and 7.1mm less deeper than Polk RTi A1 but it is also 13.2mm taller.
Below you can see the front view size comparison of Polk RTi A1 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 A1 is approximately 547.7cm2 / 84.9inch2 and base area of the Wharfedale Reva 1 is approximately 495.9cm2 / 76.9inch2. The RTi A1 requires 10% 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 A1 weighs 5.44kg / 12lbs and the Wharfedale Reva 1 weighs 5.64kg / 12.4lbs. This makes the Reva 1 4% heavier than the RTi A1.
Here is a comparison of how RTi A1 and Reva 1's weights compare with the average, max and min weights in Passive Bookshelf class.
