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 TSi200 have the same Impedance of 8 ohms and their sensitivity is also same at 89 dB.

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 and TSi200 has the same power range of 20-150 watts.
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
RTi A3 features Pair of Dual 5-way Binding Posts - Gold-Plated posts which make bi-amping or bi-wiring possible. TSi200 has a Pair of 5-way binding posts - Gold-plated which doesn't feature bi-amping/bi-wiring.
Cabinet Type and Port Position
RTi A3 has a back and front firing port whereas TSi200 has a rear 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 Polk TSi200'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 Polk TSi200 has external dimensions of 392.1 x 203.2 x 298.5mm ( 15.4 x 8.0 x 11.7inch) .
Polk TSi200 is 11.2mm narrower and 57.1mm less deeper than Polk RTi A3 but it is also 17.4mm taller.
Below you can see the front view size comparison of Polk RTi A3 and Polk TSi200 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 Polk TSi200 is approximately 606.6cm2 / 94.0inch2. The RTi A3 requires 26% more surface area than the TSi200 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 Polk TSi200 weighs 7.71kg / 17lbs. This makes the TSi200 6% heavier than the RTi A3.
Here is a comparison of how RTi A3 and TSi200's weights compare with the average, max and min weights in Passive Bookshelf class.
