Drivers

One of the fundamental differences between these two speakers is that 603 S3 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.

Driver Setup 3-way 2-way
Tweeter 1-inch 1-inch
Midrange 1 x 6-inch -
Woofer 2 x 6.5-inch 2 x 6.5-inch

603 S3 features a 1" Titanium Decoupled Double Dome Tweeter , a 6" Midrange and 2 x 6.5" Paper 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

603 S3 has a frequency range of 46-28k Hz whereas R600 has a frequency range of 43-38k Hz. With a minimum frequency of 43Hz, the R600 can go slightly deeper then the 603 S3's min frequency of 46Hz.

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

603 S3 and R600 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. 603 S3 sensitivity is rated at 90 dB and the R600's is at 87.5 dB. This 2 dB difference makes the B&W 603 S3 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.

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

603 S3 features Binding post posts which make bi-amping or bi-wiring possible. R600 has a Post which doesn't feature bi-amping/bi-wiring.
