Dymension DM70 features a 1" aluminum oxide 2 x Hard-Dome Tweeter , a 5.25" Midrange and 1 x 10" Polypropelene Woofer . On the other hand, the Ultra Tower features a 1.0" aluminum Dome Tweeter , a 6.5" Midrange and 2 x 8.0" Polypropylene Woofer with a Crossover frequency at 160HZ and 2000Hz.
Frequency Response
Dymension DM70 has a frequency range of 30-23 kHz whereas Ultra Tower has a frequency range of 28-32k Hz. With a minimum frequency of 28Hz, the Ultra Tower can go slightly deeper then the Dymension DM70's min frequency of 30Hz.
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.

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 DM70 is a 4 ohms speaker compared to the Ultra Tower 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 Ultra Tower's is rated at 88 dB. This 2 dB difference makes the Definitive Dymension DM70 a more sensitive speaker compared to SVS Ultra Tower, 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.
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
Ultra Tower features Binding post posts which make bi-amping or bi-wiring possible. Dymension DM70 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 DM70's and SVS Ultra Tower'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 SVS Ultra Tower has external dimensions of 1159.0 x 355.0 x 445.0mm ( 45-5/8 x 13-15/16 x 17-1/2inch) .
Definitive Dymension DM70 is 68mm narrower and 38mm less deeper than SVS Ultra Tower but it is also 45mm taller.
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 SVS Ultra Tower is approximately 1579.8cm2 / 244.9inch2. The Dymension DM70 requires 26% less surface area than the Ultra Tower 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 Dymension DM70 weighs 33.60kg / 73.9lbs and the SVS Ultra Tower weighs 34.27kg / 75.4lbs. This makes the Ultra Tower 2% heavier than the Dymension DM70.
Here is a comparison of how Dymension DM70 and Ultra Tower's weights compare with the average, max and min weights in Passive Floor-standing class.
