Impedance and Sensitivity
Dymension DM70 is a 4 ohms speaker compared to the BP-9060 which has a nominal impedance of 8 ohms. Lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit especially when played at high volume levels, so make sure the amp you pair with the Dymension DM70 can provide this impedance level.
These two speakers also have different sensitivity levels. Dymension DM70 sensitivity is rated at 90 dB and the BP-9060's is rated at 92 dB. This 2 dB difference makes the Definitive BP-9060 a more sensitive speaker compared to Definitive Dymension DM70, 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.
Dymension DM70 and BP-9060 has the same power range of 50-300 watts.
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
Dymension DM70 features 5-Way post, RCA type posts and BP-9060 has a 5-Way post, RCA 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. In this section, we are going to compare Definitive Dymension DM70's and Definitive BP-9060's external dimensions. Definitive Dymension DM70 has external dimensions of 1204 x 287 x 407 mm ( 47.4 x 11.3 x 16.0 in) 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 Dymension DM70 is clearly the larger of the two speakers. Its body is 6mm wider, 72mm taller and 56mm deeper than Definitive BP-9060.
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 Dymension DM70 is approximately 1168.1cm2 / 181.1inch2 and base area of the Definitive BP-9060 is approximately 986.3cm2 / 152.9inch2. The Dymension DM70 requires 18% more surface area than the BP-9060 which gives it a small disadvantage 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 Dymension DM70 weighs 33.60kg / 73.9lbs and the Definitive BP-9060 weighs 22.73kg / 50lbs. This makes the Dymension DM70 48% heavier than the BP-9060.
Here is a comparison of how Dymension DM70 and BP-9060's weights compare with the average, max and min weights in Passive Floor-standing class.
