In this review, we will be comparing AE109 MII and S60, two Passive Floor-standing speakers from Acoustic Energy and Polk Audio. Let's have a brief look at the main features
of AE109 Mark II and Polk S60 first before getting into our more
detailed comparison.
What size room are the AE109 Mark II 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 AE109 Mark II 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 AE109 MII 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.

AE109 MII features a 1" fabric dome with waveguide Tweeter , a 5.2" Midrange and 1 x 5.2" paper cone Woofer with a Crossover frequency at 275Hz and 2.5kHz. 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
AE109 MII has a frequency range of 41Hz - 26kHz whereas S60 has a frequency range of 26-40k Hz. With a minimum frequency of 26Hz, the S60 can go significantly deeper on the low side and provide stronger bass compared to the AE109 MII's min frequency of 41Hz.
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
AE109 MII is a 6 ohms speaker compared to the S60 which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. AE109 MII sensitivity is rated at 89 dB and the S60's is rated at 90 dB. This 1 dB difference makes the Polk S60 a more sensitive speaker compared to AE109 Mark II, 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.
AE109 MII can handle a max power of 300 watts RMS from the amp the whereas AE109 MII has a max power handling value of 175 watts RMS , 125 watts less than the S60.
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
AE109 MII 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 AE109 Mark II 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 AE109 Mark II's and Polk S60's external dimensions. AE109 Mark II has external dimensions of 860.0 x 165.0 x 250.0mm ( 33.9 x 6.5 x 9.8inch) 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 134mm wider, 271mm taller and 151mm deeper than AE109 Mark II.
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 AE109 Mark II is approximately 412.5cm2 / 63.9inch2 and base area of the Polk S60 is approximately 1199.0cm2 / 185.8inch2. The AE109 MII requires 66% 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 AE109 Mark II weighs 16.00kg / 35.2lbs and the Polk S60 weighs 23.60kg / 51.9lbs. This makes the S60 48% heavier than the AE109 MII.
Here is a comparison of how AE109 MII and S60's weights compare with the average, max and min weights in Passive Floor-standing class.
