AE120 MII and AE107 MII are members of Acoustic Energy's AE100 series of speakers. Below you can find the loudspeakers from this series.
What size room are the AE120 Mark II and AE107 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:

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.)

Drivers
One of the fundamental differences between these two speakers is that AE120 MII is a 3-way design whereas the AE107 MII is a 2-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker.

AE120 MII features a 1" fabric dome with waveguide Tweeter, a 5.2" Midrange and 2 x 5.2" paper cone Woofer with a Crossover frequency at 300Hz and 2.7kHz. On the other hand, the 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.
Frequency Response
AE120 MII has a frequency range of 39Hz - 26kHz whereas AE107 MII has a frequency range of 55Hz - 26kHz. With a minimum frequency of 39Hz, the AE120 MII can go significantly deeper on the low side and provide stronger bass compared to the AE107 MII's min frequency of 55Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Floor-standing class in our database.
Low Frequency
Floor-standing 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
AE120 MII and AE107 MII have the same Impedance of 6 ohms and their sensitivity is also same at 90 dB.

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.
AE120 MII can handle a max power of 200 watts RMS, whereas AE107 MII has a max power handling value of 175 watts RMS, 25 watts less than the AE120 MII.
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 AE120 MII and AE107 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
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 AE120 Mark II's and AE107 Mark II's external dimensions. AE120 Mark II has external dimensions of 950.0 x 165.0 x 250.0mm (37.4 x 6.5 x 9.8inch) whereas AE107 Mark II has external dimensions of 175.0 x 380.0 x 250.0mm (6.9 x 15 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 AE120 Mark II is approximately 412.5cm2 / 63.9inch2 and base area of the AE107 Mark II is approximately 950.0cm2 / 147.3inch2. The AE120 MII requires 57% less surface area than the AE107 MII which gives it a small advantage on placement in tight spaces.
