Drivers
One of the fundamental differences between these two speakers is that BP-9040 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.

BP-9040 features a 1" annealed aluminum dome Tweeter , a 4.5" Midrange and 1 x 8" Polypropelene Woofer . 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
BP-9040 has a frequency range of 22-40k Hz whereas R600 has a frequency range of 43-38k Hz. With a minimum frequency of 22Hz, the BP-9040 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.

High Frequency
Floor-standing Speakers
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
BP-9040 and R600 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. BP-9040 sensitivity is rated at 92 dB and the R600's is at 87.5 dB. This 4 dB difference makes the Definitive BP-9040 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.
BP-9040 can handle a max power of 300 watts RMS from the amp the whereas R600 has a max power handling value of 200 watts RMS, 100 watts less than the BP-9040.
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
BP-9040 features Post type posts and R600 has a Post type posts. None of these speakers feature bi-amping/bi-wiring.

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 Definitive BP-9040's and Polk R600's external dimensions. Definitive BP-9040 has external dimensions of 993.0 x 281.0 x 351.0mm ( 39-1/16 x 11-1/16 x 13-13/16inch) whereas Polk R600 has external dimensions of 1063.8 x 280.7 x 381.6mm ( 41.9 x 11 x 15inch) .
Definitive BP-9040 is 70.8mm shorter and 30.6mm less deeper than Polk R600 but it is also 0.30000000000001mm wider.
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 Definitive BP-9040 is approximately 986.3cm2 / 152.9inch2 and base area of the Polk R600 is approximately 1071.2cm2 / 166.0inch2. The BP-9040 requires 8% less surface area than the R600 which gives it a small advantage on placement in tight spaces.
