Let's have a brief look at the main features
of AE509 and AE500 first before getting into our more
detailed comparison.

AE509 and AE500 are members of Acoustic Energy's AE500 series of speakers. Below you can find the loudspeakers from this series.
What size room are the AE509 and AE500 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
Both AE509 and AE500 are 2-way speakers.

AE509 features a 1" carbon fibre dome with waveguide Tweeter and 2 x 5" carbon fibre cone Woofer with a Crossover frequency at 2800Hz. On the other hand, the AE500 features a 1" carbon fibre dome with waveguide Tweeter and 1 x 5" carbon fibre cone Woofer with a Crossover frequency at 2800Hz.
Frequency Response
AE509 has a frequency range of 32Hz - 28kHz whereas AE500 has a frequency range of 45Hz - 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.
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
AE509 and AE500 have the same Impedance of 6 ohms but where they differ is the sensitivity levels. AE509 sensitivity is rated at 89 dB and the AE500's is at 87 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.
Sensitivity
Floor-standing Speakers
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.
AE509 can handle a max power of 175 watts RMS, whereas AE500 has a max power handling value of 100 watts RMS, 75 watts less than the AE509.
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 AE509 and AE500 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 AE509's and AE500's external dimensions. AE509 has external dimensions of 1000.0 x 185.0 x 270.0mm (39.4 x 7.3 x 10.6inch) whereas AE500 has external dimensions of 310.0 x 185.0 x 260.0mm (12.2 x 7.3 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 AE509 is approximately 499.5cm2 / 77.4inch2 and base area of the AE500 is approximately 481.0cm2 / 74.6inch2. The AE509 requires 4% more surface area than the AE500 which gives it a small disadvantage on placement in tight spaces.
