In this review, we will be comparing BW 607 and BW 606, two Passive Bookshelf speakers by Bowers & Wilkins. Let's have a brief look at the main features of B&W 607 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 B&W 607 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 BW 607 and BW 606 are 2-way speakers. BW 607 features a 1" Decoupled Carbon Hard-Dome Tweeter and 1 x 5" Continuum Woofer . On the other hand, BW 606 features a 1" Decoupled Carbon Decoupled Dome Tweeter and 1 x 6.5" Continuum Woofer .
BW 607 and BW 606 has exactly the same frequency range of 52-28k Hz.
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
BW 607 and BW 606 has the same Impedance of 8 ohms but where they differ is the sensitivity levels. BW 607 sensitivity is rated at 84 dB and BW 606's is at 88 dB. This 4 dB difference makes B&W 606 a more sensitive speaker compared to B&W 607, 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.
BW 607 can handle a max power of 120 watts RMS from the amp the whereas BW 607 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 BW 607 and BW 606 features dual binding post speaker terminals for bi-amping or bi-wiring.
Cabinet Type and Port Position
Both BW 607 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 B&W 607's and B&W 606's external dimensions. B&W 607 has external dimensions of 300.0 x 165.0 x 207.0mm ( 11.8 x 6.4 x 8.1inch) 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 clearly the larger of the two speakers. Its body is 25mm wider, 45mm taller and 117mm deeper than B&W 607.
Below you can see the front view size comparison of B&W 607 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 B&W 607 is approximately 341.6cm2 / 52.9inch2 and base area of the B&W 606 is approximately 615.6cm2 / 95.4inch2. The BW 607 requires 45% less surface area than the BW 606 which gives it a small advantage on placement in tight spaces.
