What size room are the AE107 Mark II and AE100 Mark II 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* AE107 Mark II AE100 Mark II
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 AE107 Mark II and AE100 Mark II compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Driver Setup 2-way 2-way
Tweeter 1-inch 1-inch
Midrange - -

AE107 MII features a 1" fabric soft dome with waveguide Tweeter and 2 x 5.2" paper cone Woofer with a Crossover frequency at 2200Hz. On the other hand, the 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.

Frequency Response

AE107 MII has a frequency range of 55Hz - 26kHz whereas AE100 MII has a frequency range of 51Hz - 26kHz. With a minimum frequency of 51Hz, the AE100 MII can go slightly deeper then the AE107 MII's min frequency of 55Hz.

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 Center Channel 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

AE107 MII and AE100 MII have the same Impedance of 6 ohms but where they differ is the sensitivity levels. AE107 MII sensitivity is rated at 90 dB and the AE100 MII's is at 87 dB. This 3 dB difference makes the AE107 Mark II 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.

AE107 MII can handle a max power of 175 watts RMS from the amp the whereas AE100 MII has a max power handling value of 120 watts RMS, 55 watts less than the AE107 MII.

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 AE107 MII and AE100 MII 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 AE107 Mark II's and AE100 Mark II's external dimensions. AE107 Mark II has external dimensions of 175.0 x 380.0 x 250.0mm ( 6.9 x 15 x 9.8inch) whereas AE100 Mark II has external dimensions of 290.0 x 165.0 x 250.0mm ( 11.4 x 6.5 x 9.8inch) .

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 AE107 Mark II is approximately 950.0cm2 / 147.3inch2 and base area of the AE100 Mark II is approximately 412.5cm2 / 63.9inch2. The AE107 MII requires 130% more surface area than the AE100 MII which gives it a small disadvantage on placement in tight spaces.
