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.
Input Type and Bi-Amping / Bi-Wiring
Demand D15 features 5-Way post posts which make bi-amping or bi-wiring possible. BP-9060 has a 5-Way post, RCA 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 Definitive Demand D15's and Definitive BP-9060's external dimensions. Definitive Demand D15 has external dimensions of 1023.0 x 231.0 x 324.0mm ( 40-1/4 x 9-1/16 x 12-3/4inch) whereas Definitive BP-9060 has external dimensions of 1132.0 x 281.0 x 351.0mm ( 44-9/16 x 11-1/16 x 13-13/16inch) .
Definitive BP-9060 is clearly the larger of the two speakers. Its body is 50mm wider, 109mm taller and 27mm deeper than Definitive Demand D15.
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 Definitive Demand D15 is approximately 748.4cm2 / 116.0inch2 and base area of the Definitive BP-9060 is approximately 986.3cm2 / 152.9inch2. The Demand D15 requires 24% less surface area than the BP-9060 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 Definitive Demand D15 weighs 23.60kg / 51.9lbs and the Definitive BP-9060 weighs 22.73kg / 50lbs. This makes the Demand D15 4% heavier than the BP-9060.
Here is a comparison of how Demand D15 and BP-9060's weights compare with the average, max and min weights in Passive Floor-standing class.
