In this review, we will be comparing RP-600M and BW 606, two Passive Bookshelf speakers from Klipsch and Bowers & Wilkins. Let's have a brief look at the main features of Klipsch RP-600M and B&W 606 first before getting into our more detailed comparison.
In the following sections, we will get into details in order to better understand how Klipsch RP-600M and B&W 606 compares and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Both RP-600M and BW 606 are 2-way speakers. RP-600M features a 1" Tractrix Horn Tweeter and 1 x 6.5" Cerametallic Woofer with a Crossover frequency at 1500Hz. On the other hand, BW 606 features a 1" Decoupled Carbon Decoupled Dome Tweeter and 1 x 6.5" Continuum Woofer .
RP-600M has a frequency range of 45-25k Hz whereas BW 606 has a frequency range of 52-28k Hz. With a minimum frequency of 45Hz, the RP-600M can go significantly deeper on the low side and provide stronger bass compared to the BW 606's min frequency of 52Hz.
Below graphs depict how these two speakers compare with the max, min and average values of the Min and Max Frequencies of other speakers under Bookshelf class in our database.
Impedance and Sensitivity
RP-600M and BW 606 has the same Impedance of 8 ohms but where they differ is the sensitivity levels. RP-600M sensitivity is rated at 96 dB and BW 606's is at 88 dB. This 8 dB difference makes Klipsch RP-600M a more sensitive speaker compared to B&W 606, hence will play louder with the same amount of watts.
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.
RP-600M can handle a max power of 120 watts RMS from the amp the whereas RP-600M has a max power handling value of 100 watts RMS , 20 watts less than the BW 606.
Keep in mind that higher max power handling value doesn't necesssarily make that a louder speaker compared to a lower max handling speaker. Loudness or the sound level is also impacted by parameters such as Impededance, sensitivity and system efficiencies.
Input Type and Bi-Amping / Bi-Wiring
Both RP-600M and BW 606 features dual binding post speaker terminals for bi-amping or bi-wiring.
Cabinet Type and Port Position
Both RP-600M and BW 606 have rear firing ports. Rear ported speakers generlly need more room between the backside of the speaker and the wall compared to sealed and front/bottom ported speakers. Placing too close to the walls may cause the bass to sound boomy.
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 Klipsch RP-600M's and B&W 606's external dimensions. Klipsch RP-600M has external dimensions of 399.0 x 202.0 x 301.0mm ( 15.7 x 7.9 x 11.8inch) whereas B&W 606 has external dimensions of 345.0 x 190.0 x 324.0mm ( 13.5 x 7.4 x 12.7inch) .
B&W 606 is 12mm narrower and 54mm shorter than Klipsch RP-600M but it is also 23mm deeper.
Below you can see the front view size comparison of Klipsch RP-600M and B&W 606 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 Klipsch RP-600M is approximately 608.0cm2 / 94.2inch2 and base area of the B&W 606 is approximately 615.6cm2 / 95.4inch2. The RP-600M requires 1% less surface area than the BW 606 which gives it a small advantage on placement in tight spaces.
