Dymension DM80 features a 1" aluminum oxide 2 x Hard-Dome Tweeter , a 5.25" Midrange and 1 x 12" Polypropelene Woofer . On the other hand, the 702 S3 features a 1" Tweeter , a 6" Midrange and 3 x 6.5" Aerofoil Woofer .
Frequency Response
Dymension DM80 has a frequency range of 28-23 kHz whereas 702 S3 has a frequency range of 46-28k Hz. With a minimum frequency of 28Hz, the Dymension DM80 can go significantly deeper on the low side and provide stronger bass compared to the 702 S3's min frequency of 46Hz.
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.

Definitive Dymension DM80
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
Dymension DM80 is a 4 ohms speaker compared to the 702 S3 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 DM80 can provide this impedance level.
On the other hand, they have the same sensitivity of 90 dBdB.

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
702 S3 features Binding post posts which make bi-amping or bi-wiring possible. Dymension DM80 has a Binding 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 Definitive Dymension DM80's and B&W 702 S3's external dimensions. Definitive Dymension DM80 has external dimensions of 1255 x 287 x 407 mm ( 49.4 x 11.3 x 16.0 in) whereas B&W 702 S3 has external dimensions of 1138.0 x 192.0 x 391.0mm ( 44.8-inch x 7.6-inch x 15.4-inch) .
Definitive Dymension DM80 is clearly the larger of the two speakers. Its body is 95mm wider, 117mm taller and 16mm deeper than B&W 702 S3.
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 DM80 is approximately 1168.1cm2 / 181.1inch2 and base area of the B&W 702 S3 is approximately 750.7cm2 / 116.4inch2. The Dymension DM80 requires 56% more surface area than the 702 S3 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 DM80 weighs 37.70kg / 82.9lbs and the B&W 702 S3 weighs 33.46kg / 73.6lbs. This makes the Dymension DM80 13% heavier than the 702 S3.
Here is a comparison of how Dymension DM80 and 702 S3's weights compare with the average, max and min weights in Passive Floor-standing class.
