In this review, we will be comparing L100 and BW 606, two Passive Bookshelf speakers from Polk Audio and Bowers Wilkins. Let's have a brief look at the main features
of Polk L100 and B&W 606 first before getting into our more
detailed comparison.
What size room are the Polk L100 and B&W 606 speakers good for?
The size of the room in which you are planning to use these loudspeakers is an important decision factor. Here we have compared their suitability to various sizes of environments considering their size and max power parameters:
In the following sections, we will get into more detail in order to better understand how the Polk L100 and B&W 606 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

L100 features a 1" Ring Radiator Tweeter and 1 x 5.25" Polypropylene Woofer with a Crossover frequency at 2900Hz. On the other hand, the BW 606 features a 1" Decoupled Carbon Hard-Dome Tweeter and 1 x 6.5" Continuum Woofer .
Frequency Response
L100 has a frequency range of 57-38k Hz whereas BW 606 has a frequency range of 52-28k Hz. With a minimum frequency of 52Hz, the BW 606 can go significantly deeper on the low side and provide stronger bass compared to the L100's min frequency of 57Hz.
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 Bookshelf 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
L100 is a 4 ohms speaker compared to the BW 606 which has a nominal impedance of 8 ohms. Lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit especially when played at high volume levels, so make sure the amp you pair with the L100 can provide this impedance level.
These two speakers also have different sensitivity levels. L100 sensitivity is rated at 85.5 dB and the BW 606's is rated at 88 dB. This 2 dB difference makes the B&W 606 a more sensitive speaker compared to Polk L100, 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.
L100 can handle a max power of 160 watts RMS from the amp the whereas BW 606 has a max power handling value of 120 watts RMS, 40 watts less than the L100.
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
BW 606 features Post posts which make bi-amping or bi-wiring possible. L100 has a Post which doesn't feature bi-amping/bi-wiring.

B&W 606's Post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both L100 and BW 606 have rear firing ports. Rear ported speakers generally need more room between the backside of the speaker and the wall compared to sealed and front/bottom ported speakers. Placing the speakers too close to the walls may cause the bass to sound boomy.
If you are limited in space and can't get the speakers away from the backwall, check our Speakers with Front Firing Ports page.

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 Polk L100's and B&W 606's external dimensions. Polk L100 has external dimensions of 348.0 x 201.0 x 288.0mm ( 13-11/16 x 7-7/8 x 11-5/16inch) 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 11mm narrower and 3mm shorter than Polk L100 but it is also 36mm deeper.
Below you can see the front view size comparison of Polk L100 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 Polk L100 is approximately 578.9cm2 / 89.7inch2 and base area of the B&W 606 is approximately 615.6cm2 / 95.4inch2. The L100 requires 6% less surface area than the BW 606 which gives it a small advantage on placement in tight spaces.
Here is an another comparison that shows both speakers on a BDI Octave Media Cabinet, next to a standard size amplifier and turntable in scale:

Weight Comparison The weight of a loudspeaker can become an important factor if you need to move and reposition the unit often. Weight of a speaker can also "sometimes" be an indicator of the rigidity of the enclosure and the quality of the internal components used. The Polk L100 weighs 7.68kg / 16.9lbs and the B&W 606 weighs 6.90kg / 15.2lbs. This makes the L100 11% heavier than the BW 606.
Here is a comparison of how L100 and BW 606's weights compare with the average, max and min weights in Passive Bookshelf class.
