In this review, we will be comparing R600 and RTi A9, two Passive Floor-standing speakers by Polk Audio Let's have a brief look at the main features
of Polk R600 and Polk RTi A9 first before getting into our more
detailed comparison.
What size room are the Polk R600 and Polk RTi A9 speakers good for?
The size of the room in which you are planning to use these loudspeakers is an important decision factor. Here we have compared their suitability to various sizes of environments considering their size and max power parameters:
In the following sections, we will get into more detail in order to better understand how the Polk R600 and Polk RTi A9 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Drivers
One of the fundamental differences between these two speakers is that R600 is a 2-way design whereas the RTi A9 is a 3-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker.

R600 features a 1" Pinnacle Ring Radiator Tweeter and 2 x 6.5" Polypropylene Turbine Cone Woofer with a Crossover frequency at 2700Hz. On the other hand, the RTi A9 features a 1" Tweeter , a 5.25" Midrange and 3 x 7" Polymer composite Woofer .
Frequency Response
R600 has a frequency range of 43-38k Hz whereas RTi A9 has a frequency range of 30-26k Hz. With a minimum frequency of 30Hz, the RTi A9 can go significantly deeper on the low side and provide stronger bass compared to the R600's min frequency of 43Hz.
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 Floor-standing 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
R600 and RTi A9 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. R600 sensitivity is rated at 87.5 dB and the RTi A9's is at 90 dB. This 2 dB difference makes the Polk RTi A9 a more sensitive speaker compared to Polk R600, 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.
R600 can handle a max power of 500 watts RMS from the amp the whereas R600 has a max power handling value of 200 watts RMS , 300 watts less than the RTi A9.
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 A9 features 5-way post posts which make bi-amping or bi-wiring possible. R600 has a Post which doesn't feature bi-amping/bi-wiring.

Cabinet Type and Port Position
R600 has a bottom firing port whereas RTi A9 has a front firing ports. Polk RTi A9's front-firing port gives more flexibility in placement in regards to proximity to walls compared to Polk R600 with its rear-firing port.

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 R600's and Polk RTi A9's external dimensions. Polk R600 has external dimensions of 1063.8 x 280.7 x 381.6mm ( 41.9 x 11 x 15inch) whereas Polk RTi A9 has external dimensions of 1221.0 x 272.0 x 547.0mm ( 48-1/16 x 10-11/16 x 21-1/2inch) .
Polk R600 is 157.2mm shorter and 165.4mm less deeper than Polk RTi A9 but it is also 8.7mm wider.
Below you can see the front view size comparison of Polk R600 and Polk RTi A9 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 R600 is approximately 1071.2cm2 / 166.0inch2 and base area of the Polk RTi A9 is approximately 1487.8cm2 / 230.6inch2. The R600 requires 28% less surface area than the RTi A9 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 Polk R600 weighs 21.50kg / 47.3lbs and the Polk RTi A9 weighs 34.09kg / 75lbs. This makes the RTi A9 59% heavier than the R600.
