AE500 and AE509 are members of Acoustic Energy's AE500 series of speakers. Below you can find the loudspeakers from this series.
What size room are the AE500 and AE509 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:

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 AE500 and AE509 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

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 AE509 features a 1" carbon fibre dome with waveguide Tweeter and 2 x 5" carbon fibre cone Woofer with a Crossover frequency at 2800Hz.
Frequency Response
AE500 has a frequency range of 45Hz - 28kHz whereas AE509 has a frequency range of 32Hz - 28kHz. With a minimum frequency of 32Hz, the AE509 can go significantly deeper on the low side and provide stronger bass compared to the AE500'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
AE500 and AE509 have the same Impedance of 6 ohms but where they differ is the sensitivity levels. AE500 sensitivity is rated at 87 dB and the AE509's is at 89 dB. This 2 dB difference makes the AE509 a more sensitive speaker compared to AE500, 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.
AE500 can handle a max power of 175 watts RMS from the amp the whereas AE500 has a max power handling value of 100 watts RMS , 75 watts less than the AE509.
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 AE500 and AE509 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 AE500's and AE509'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 AE509 has external dimensions of 1000.0 x 185.0 x 270.0mm ( 39.4 x 7.3 x 10.6inch) .
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 AE509 is approximately 499.5cm2 / 77.4inch2. The AE500 requires 4% less surface area than the AE509 which gives it a small advantage on placement in tight spaces.
