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.
XT60 can handle a max power of 200 watts RMS from the amp the whereas XT15 has a max power handling value of 150 watts RMS, 50 watts less than the XT60.
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
XT60 features 5-Way post type posts and XT15 has a 5-Way post type posts. None of these speakers 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.

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 XT60 is approximately 584.4cm2 / 90.6inch2 and base area of the Polk XT15 is approximately 305.6cm2 / 47.4inch2. The XT60 requires 91% more surface area than the XT15 which gives it a small disadvantage on placement in tight spaces.
