In this review, we will be comparing AE500 and 606 S2 AE, two Passive Bookshelf speakers from Acoustic Energy and Bowers Wilkins. Let's have a brief look at the main features
of AE500 and B&W 606 S2 first before getting into our more
detailed comparison.
What size room are the AE500 and B&W 606 S2 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 AE500 and B&W 606 S2 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

AE500 features a 1" carbon fibre dome with waveguide Tweeter and 1 x 5" carbon fibre cone Woofer with a Crossover frequency at 2800Hz. On the other hand, the 606 S2 AE features a 1" Aluminum Decoupled Double Dome Tweeter and 1 x 6.5" Continuum Woofer .
Frequency Response
AE500 has a frequency range of 45Hz - 28kHz whereas 606 S2 AE has a frequency range of 52-28k Hz. With a minimum frequency of 45Hz, the AE500 can go significantly deeper on the low side and provide stronger bass compared to the 606 S2 AE'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 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
AE500 is a 6 ohms speaker compared to the 606 S2 AE which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. AE500 sensitivity is rated at 87 dB and the 606 S2 AE's is rated at 88 dB. This 1 dB difference makes the B&W 606 S2 a more sensitive speaker compared to AE500, 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.
AE500 can handle a max power of 120 watts RMS from the amp the whereas AE500 has a max power handling value of 100 watts RMS , 20 watts less than the 606 S2 AE.
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.
Cabinet Type and Port Position
Both AE500 and 606 S2 AE 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 AE500's and B&W 606 S2's external dimensions. AE500 has external dimensions of 310.0 x 185.0 x 260.0mm ( 12.2 x 7.3 x 10.2inch) whereas B&W 606 S2 has external dimensions of 347.0 x 191.0 x 326.0mm ( 13-5/8 x 7-1/2 x 12-13/16inch) .
B&W 606 S2 is clearly the larger of the two speakers. Its body is 6mm wider, 37mm taller and 66mm deeper than AE500.
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 AE500 is approximately 481.0cm2 / 74.6inch2 and base area of the B&W 606 S2 is approximately 622.7cm2 / 96.5inch2. The AE500 requires 23% less surface area than the 606 S2 AE which gives it a small advantage on placement in tight spaces.
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 AE500 weighs 8.00kg / 17.6lbs and the B&W 606 S2 weighs 6.90kg / 15.2lbs. This makes the AE500 16% heavier than the 606 S2 AE.
Here is a comparison of how AE500 and 606 S2 AE's weights compare with the average, max and min weights in Passive Bookshelf class.
