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
ES60 and ES15 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. ES60 sensitivity is rated at 90 dB and the ES15's is at 85 dB. This 5 dB difference makes the Polk ES60 a more sensitive speaker compared to Polk ES15, 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.
ES60 can handle a max power of 300 watts RMS from the amp the whereas ES15 has a max power handling value of 100 watts RMS, 200 watts less than the ES60.
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.
Input Type and Bi-Amping / Bi-Wiring
ES60 features 5-Way post posts which make bi-amping or bi-wiring possible. ES15 has a 5-Way post which doesn't feature bi-amping/bi-wiring.

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 Polk ES60's and Polk ES15's external dimensions. Polk ES60 has external dimensions of 1131.0 x 216.0 x 401.0mm ( 44-1/2 x 8-1/2 x 15-3/4inch) whereas Polk ES15 has external dimensions of 307.0 x 193.0 x 259.0mm ( 12-1/16 x 7-9/16 x 10-3/16inch) .
Polk ES60 is clearly the larger of the two speakers. Its body is 23mm wider, 824mm taller and 142mm deeper than Polk ES15.
Below you can see the front view size comparison of Polk ES60 and Polk ES15 in scale.

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 Polk ES60 is approximately 866.2cm2 / 134.3inch2 and base area of the Polk ES15 is approximately 499.9cm2 / 77.5inch2. The ES60 requires 73% more surface area than the ES15 which gives it a small disadvantage on placement in tight spaces.
