Drivers
One of the fundamental differences between these two speakers is that Ultra Evolution Tower is a 3-way design whereas the Ultra Evolution Nano is a 2-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker.

Ultra Evolution Tower features a 1" aluminum Dome Tweeter , a 4.5" Midrange and 4 x 5.25" Composite glass-fiber Woofer with a Crossover frequency at 170HZ and 1800Hz. On the other hand, the Ultra Evolution Nano features a 1" aluminum Dome Tweeter and 1 x 5.25" Composite glass-fiber Woofer with a Crossover frequency at 1900Hz.
Frequency Response
Ultra Evolution Tower has a frequency range of 30-40k Hz whereas Ultra Evolution Nano has a frequency range of 44-40k Hz. With a minimum frequency of 30Hz, the Ultra Evolution Tower can go significantly deeper on the low side and provide stronger bass compared to the Ultra Evolution Nano's min frequency of 44Hz.
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
Ultra Evolution Tower and Ultra Evolution Nano have the same Impedance of 6 ohms but where they differ is the sensitivity levels. Ultra Evolution Tower sensitivity is rated at 87 dB and the Ultra Evolution Nano's is at 85 dB. This 2 dB difference makes the SVS Ultra Evolution Tower a more sensitive speaker compared to SVS Ultra Evolution Nano, 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.
Ultra Evolution Tower can handle a max power of 300 watts RMS from the amp the whereas Ultra Evolution Nano has a max power handling value of 150 watts RMS, 150 watts less than the Ultra Evolution Tower.
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 Evolution Tower features Gold-plated 5-way posts which make bi-amping or bi-wiring possible. Ultra Evolution Nano has a Gold-plated 5-way which doesn't feature bi-amping/bi-wiring.
SVS Ultra Evolution Tower's Gold-plated 5-way terminals allows Bi-amping or bi-wiring

Cabinet Type and Port Position
Both Ultra Evolution Tower and Ultra Evolution Nano have rear firing ports. Rear ported speakers generally need more room between the backside of the speaker and the wall compared to sealed and front/bottom ported speakers. Placing the speakers too close to the walls may cause the bass to sound boomy.
If you are limited in space and can't get the speakers away from the backwall, check our Speakers with Front Firing Ports page.
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 SVS Ultra Evolution Tower's and SVS Ultra Evolution Nano's external dimensions. SVS Ultra Evolution Tower has external dimensions of 1130 x 218 x 424mm ( 44.49 x 8.58 x 16.69”) whereas SVS Ultra Evolution Nano has external dimensions of 314 x 190 x 243mm ( 12.36 x 7.48 x 9.57”) .
SVS Ultra Evolution Tower is clearly the larger of the two speakers. Its body is 28mm wider, 816mm taller and 181mm deeper than SVS Ultra Evolution Nano.
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 SVS Ultra Evolution Tower is approximately 924.3cm2 / 143.3inch2 and base area of the SVS Ultra Evolution Nano is approximately 461.7cm2 / 71.6inch2. The Ultra Evolution Tower requires 100% more surface area than the Ultra Evolution Nano which gives it a small disadvantage on placement in tight spaces.
