AE300 and AE320 are members of Acoustic Energy's AE300 series of speakers. Below you can find the loudspeakers from this series.
What size room are the AE300 and AE320 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.)
In the following sections, we will get into more detail in order to better understand how the AE300 and AE320 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Drivers
One of the fundamental differences between these two speakers is that AE300 is a 2-way design whereas the AE320 is a 3-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.

AE300 features a 1.1" aluminium dome with waveguide Tweeter and 1 x 5.2" ceramic aluminium sandwich Woofer with a Crossover frequency at 2800Hz. On the other hand, the AE320 features a 1.1" aluminium dome with waveguide Tweeter , a 5.2" Midrange and 2 x 5.2" ceramic aluminium sandwich Woofer with a Crossover frequency at 380Hz and 3400Hz.
Frequency Response
AE300 has a frequency range of 45Hz - 30kHz whereas AE320 has a frequency range of 35Hz - 30kHz. With a minimum frequency of 35Hz, the AE320 can go significantly deeper on the low side and provide stronger bass compared to the AE300's min frequency of 45Hz.
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.

High Frequency

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
AE300 is a 6 ohms speaker compared to the AE320 which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. AE300 sensitivity is rated at 86 dB and the AE320's is rated at 90 dB. This 4 dB difference makes the AE320 a more sensitive speaker compared to AE300, 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.
AE300 can handle a max power of 200 watts RMS from the amp the whereas AE300 has a max power handling value of 100 watts RMS , 100 watts less than the AE320.
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 AE300 and AE320 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 AE300's and AE320's external dimensions. AE300 has external dimensions of 300.0 x 175.0 x 260.0mm ( 11.4 x 6.9 x 10.2inch) whereas AE320 has external dimensions of 1000.0 x 175.0 x 260.0mm ( 39.4 x 6.9 x 10.2inch) .
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 AE300 is approximately 455.0cm2 / 70.5inch2 and base area of the AE320 is approximately 455.0cm2 / 70.5inch2.
