What size room are the AE500 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:

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 BW 606 features a 1" Decoupled Carbon Hard-Dome Tweeter and 1 x 6.5" Continuum Woofer.
Frequency Response
AE500 has a frequency range of 45Hz - 28kHz whereas BW 606 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 BW 606's min frequency of 52Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Bookshelf class in our database.
Low Frequency
Bookshelf Speakers
Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. 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 BW 606 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 BW 606's is rated at 88 dB. This 1 dB difference makes the B&W 606 a more sensitive speaker compared to AE500, hence will play louder with the same amount of watts.
Sensitivity

Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
BW 606 can handle a max power of 120 watts RMS, whereas AE500 has a max power handling value of 100 watts RMS, 20 watts less than the BW 606.
Note that higher power handling does not make a speaker louder: that depends mainly on
sensitivity and impedance. The calculator below shows how loud each of these actually plays
on a real amplifier.
Which plays louder on your amplifier?
Starting with a popular amplifier — change it to the one you own, or any you are
considering, and watch both numbers move.
Cabinet Type and Port Position
Both AE500 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
The size of a speaker can sometimes be 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'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 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 5mm wider, 35mm taller and 64mm 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 is approximately 615.6cm2 / 95.4inch2. The AE500 requires 22% less surface area than the BW 606 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 weighs 6.90kg / 15.2lbs. This makes the AE500 16% heavier than the BW 606.
Here is a comparison of how AE500 and BW 606's weights compare with the average, max and min weights in Passive Bookshelf class.

These sit in different price classes - AE500 costs roughly 1.7x what B&W 606 does. Expect it to lead on paper; the question is whether the gap is audible enough in your room to be worth it.
| Area | Better | Why |
|---|
| Bass |
A |
AE500 digs deeper - 45Hz against 52Hz. A subwoofer would even that out. |
| Amplifier needs |
evenly matched |
Similar sensitivity (87dB vs 88dB) - both want much the same power. |
| Amplifier match |
B |
B&W 606 is the easier load at 8 ohms. |
| Headroom |
evenly matched |
Similar power handling (100W vs 120W). |
| Size |
depends |
AE500 is easier to place; B&W 606 is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability |

B&W 606: bi-amping. |

B&W 606 is cheaper - $899 against $1,499, about 40% less; arguably a different class. |
A AE500
B B&W 606
depends neither is better in the abstract - it turns on your room, placement or how you will use them.
Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
B&W 606 has the edge on paper, though the margin is not large. The rows marked "depends" may matter more to you than the score does. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 52Hz anyway, which makes the cheaper B&W 606 much easier to justify. Match it to your room: we rate AE500 the better fit for near-field listening and a small room, and B&W 606 for a mid-size room and a large room.
And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
