In this review, we will be comparing AE520 and S60, two Passive Floor-standing speakers from Acoustic Energy and Polk Audio. Let's have a brief look at the main features
of AE520 and Polk S60 first before getting into our more
detailed comparison.
What size room are the AE520 and Polk S60 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:
In the following sections, we will get into more detail in order to better understand how the AE520 and Polk S60 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 AE520 is a 3-way design whereas the S60 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.

AE520 features a 1" carbon fibre dome with waveguide Tweeter , a 5.2" Midrange and 4 x 5" carbon fibre cone Woofer with a Crossover frequency at 373Hz and 2.8kHz. On the other hand, the S60 features a 1" Terylene Dome Tweeter and 3 x 6.5" Mica-reinforced polypropylene Woofer with a Crossover frequency at 2500Hz.
Frequency Response
AE520 has a frequency range of 30Hz - 28kHz whereas S60 has a frequency range of 26-40k Hz. With a minimum frequency of 26Hz, the S60 can go slightly deeper then the AE520's min frequency of 30Hz.
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 Floor-standing 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
AE520 is a 6 ohms speaker compared to the S60 which has a nominal impedance of 8 ohms.
On the other hand, they have the same sensitivity of 90 dBdB.

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.
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
AE520 has a rear firing port whereas S60 has a bottom firing ports. Polk S60's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to AE520 with its rear-firing port.
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 AE520's and Polk S60's external dimensions. AE520 has external dimensions of 1130.0 x 185.0 x 320.0mm ( 44.5 x 7.3 x 12.6inch) whereas Polk S60 has external dimensions of 1131.0 x 299.0 x 401.0mm ( 44-1/2 x 11-3/4 x 15-3/4inch) .
Polk S60 is clearly the larger of the two speakers. Its body is 114mm wider, 1mm taller and 81mm deeper than AE520.
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 AE520 is approximately 592.0cm2 / 91.8inch2 and base area of the Polk S60 is approximately 1199.0cm2 / 185.8inch2. The AE520 requires 51% less surface area than the S60 which gives it a small advantage on placement in tight spaces.
Weight Comparison The weight of a loudspeaker can become an important factor if you need to move and reposition the unit often. Weight of a speaker can also "sometimes" be an indicator of the rigidity of the enclosure and the quality of the internal components used. The AE520 weighs 30.00kg / 66lbs and the Polk S60 weighs 23.60kg / 51.9lbs. This makes the AE520 27% heavier than the S60.
Here is a comparison of how AE520 and S60's weights compare with the average, max and min weights in Passive Floor-standing class.
