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 Center and Ultra Center has the same power range of 20-225 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
Both Ultra Evolution Center and Ultra Center features dual binding post speaker terminals for bi-amping or bi-wiring.
SVS Ultra Evolution Center's Gold-plated 5-way terminals allows Bi-amping or bi-wiring
SVS Ultra Center's 5-Way post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both Ultra Evolution Center and Ultra 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 Center's and SVS Ultra Center's external dimensions. SVS Ultra Evolution Center has external dimensions of 199 x 560 x 299.2mm ( 7.83 x 22.05 x 11.78”) whereas SVS Ultra Center has external dimensions of 207.0 x 561.0 x 285.0mm ( 8-1/8 x 22-1/16 x 11-3/16inch) .
SVS Ultra Evolution Center is 1mm narrower and 8mm shorter than SVS Ultra Center but it is also 14mm deeper.
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 Center is approximately 1674.4cm2 / 259.5inch2 and base area of the SVS Ultra Center is approximately 1598.9cm2 / 247.8inch2. The Ultra Evolution Center requires 5% more surface area than the Ultra Center 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 SVS Ultra Evolution Center weighs 12.20kg / 26.8lbs and the SVS Ultra Center weighs 14.09kg / 31lbs. This makes the Ultra Center 15% heavier than the Ultra Evolution Center.
Here is a comparison of how Ultra Evolution Center and Ultra Center's weights compare with the average, max and min weights in Passive Center Channel class.
