What size room are the AE100 Mark II 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:

Listening Environment* AE100 Mark II B&W 606 S2
Near-field Poor Poor
Small Room Average Average
Mid-size Room Good Good
Large Room Average Average
Very Large Room Poor Poor

(* Approximate Room sizes: Small < 100sq. ft / 9 m2, Mid-size: 100-220 sq. ft / 9-20 m2, Large 220-400 sq. ft / 20-36 m2, Very Large: > 400 sq. ft / 36 m2. Average Floor Height: 9" / 2.7m. Typical room sizes differ from country to country, and the actual listening experience changes depending on floor height, room shape, surface materials, listening position, speaker locations, etc.)

In the following sections, we will get into more detail in order to better understand how the AE100 Mark II 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.

AE100 MII features a 1" fabric soft dome with waveguide Tweeter and 1 x 5.2" paper cone Woofer with a Crossover frequency at 2900Hz. 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

AE100 MII has a frequency range of 51Hz - 26kHz whereas 606 S2 AE has a frequency range of 52-28k Hz. With a minimum frequency of 51Hz, the AE100 MII can go slightly deeper then 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

AE100 MII 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. AE100 MII 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 AE100 Mark II, 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.

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 AE100 MII 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 AE100 Mark II's and B&W 606 S2's external dimensions. AE100 Mark II has external dimensions of 290.0 x 165.0 x 250.0mm ( 11.4 x 6.5 x 9.8inch) 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 26mm wider, 57mm taller and 76mm deeper than AE100 Mark II.

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 AE100 Mark II is approximately 412.5cm2 / 63.9inch2 and base area of the B&W 606 S2 is approximately 622.7cm2 / 96.5inch2. The AE100 MII requires 34% 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 AE100 Mark II weighs 4.60kg / 10.1lbs and the B&W 606 S2 weighs 6.90kg / 15.2lbs. This makes the 606 S2 AE 50% heavier than the AE100 MII.

Here is a comparison of how AE100 MII and 606 S2 AE's weights compare with the average, max and min weights in Passive Bookshelf class.
