Drivers
One of the fundamental differences between these two speakers is that Theva No3 is a 3-way design whereas the R600 is a 2-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.

Theva No3 features a 1" TNF Al/Mg inverted dome Tweeter , a 6.5" Midrange and 2 x 6.5" Slatefiber Woofer with a Crossover frequency at 270 Hz - 2700 Hz. On the other hand, the R600 features a 1" Pinnacle Ring Radiator Tweeter and 2 x 6.5" Polypropylene Turbine Cone Woofer with a Crossover frequency at 2700Hz.
Frequency Response
Theva No3 has a frequency range of 48-28kHz whereas R600 has a frequency range of 43-38k Hz. With a minimum frequency of 43Hz, the R600 can go significantly deeper on the low side and provide stronger bass compared to the Theva No3's min frequency of 48Hz.
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
Theva No3 and R600 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Theva No3 sensitivity is rated at 91 dB and the R600's is at 87.5 dB. This 3 dB difference makes the Focal Theva No3 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.
Theva No3 can handle a max power of 250 watts RMS from the amp the whereas R600 has a max power handling value of 200 watts RMS, 50 watts less than the Theva No3.
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
Theva No3 features Post type posts and R600 has a Post type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Theva No3 has a rear firing port whereas R600 has a bottom firing ports. Polk R600's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to Focal Theva No3 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 Focal Theva No3's and Polk R600's external dimensions. Focal Theva No3 has external dimensions of 991.0 x 213.0 x 388.0mm ( 39 x 83/8 x 151/4) whereas Polk R600 has external dimensions of 1063.8 x 280.7 x 381.6mm ( 41.9 x 11 x 15inch) .
Focal Theva No3 is 67.7mm narrower and 72.8mm shorter than Polk R600 but it is also 6.4mm deeper.
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 Focal Theva No3 is approximately 826.4cm2 / 128.1inch2 and base area of the Polk R600 is approximately 1071.2cm2 / 166.0inch2. The Theva No3 requires 23% less surface area than the R600 which gives it a small advantage on placement in tight spaces.
