Drivers
One of the fundamental differences between these two speakers is that Ultra Evolution Nano is a 2-way design whereas the Ultra Evolution Center is a 3-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 Nano features a 1" aluminum Dome Tweeter and 1 x 5.25" Composite glass-fiber Woofer with a Crossover frequency at 1900Hz. On the other hand, the Ultra Evolution Center features a 1" aluminum Dome Tweeter , a 4.5" Midrange and 2 x 6.5" Composite glass-fiber Woofer with a Crossover frequency at 450HZ and 2200Hz.
Frequency Response
Ultra Evolution Nano has a frequency range of 44-40k Hz whereas Ultra Evolution Center has a frequency range of 40-40k Hz. With a minimum frequency of 40Hz, the Ultra Evolution Center can go slightly deeper then 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 Bookshelf class in our database.

SVS Ultra Evolution Center
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 Nano and Ultra Evolution Center have the same Impedance of 6 ohms but where they differ is the sensitivity levels. Ultra Evolution Nano sensitivity is rated at 85 dB and the Ultra Evolution Center's is at 87 dB. This 2 dB difference makes the SVS Ultra Evolution Center 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 Nano can handle a max power of 225 watts RMS from the amp the whereas Ultra Evolution Nano has a max power handling value of 150 watts RMS , 75 watts less than the Ultra Evolution Center.
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 Center 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 Center's Gold-plated 5-way terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both Ultra Evolution Nano and Ultra Evolution Center 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 Nano's and SVS Ultra Evolution Center's external dimensions. SVS Ultra Evolution Nano has external dimensions of 314 x 190 x 243mm ( 12.36 x 7.48 x 9.57”) whereas SVS Ultra Evolution Center has external dimensions of 199 x 560 x 299.2mm ( 7.83 x 22.05 x 11.78”) .
SVS Ultra Evolution Nano is 370mm narrower and 56mm less deeper than SVS Ultra Evolution Center but it is also 115mm 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 SVS Ultra Evolution Nano is approximately 461.7cm2 / 71.6inch2 and base area of the SVS Ultra Evolution Center is approximately 1674.4cm2 / 259.5inch2. The Ultra Evolution Nano requires 72% less surface area than the Ultra Evolution Center which gives it a small advantage on placement in tight spaces.
