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 and Ultra Tower has the same power range of 20-300 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 Tower and Ultra Tower features dual binding post speaker terminals for bi-amping or bi-wiring.
SVS Ultra Evolution Tower's Gold-plated 5-way terminals allows Bi-amping or bi-wiring
SVS Ultra Tower's Binding post terminals allows Bi-amping or 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 SVS Ultra Evolution Tower's and SVS Ultra Tower'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 Tower has external dimensions of 1159.0 x 355.0 x 445.0mm ( 45-5/8 x 13-15/16 x 17-1/2inch) .
SVS Ultra Tower is clearly the larger of the two speakers. Its body is 137mm wider, 29mm taller and 21mm deeper than SVS Ultra Evolution Tower.
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 Tower is approximately 1579.8cm2 / 244.9inch2. The Ultra Evolution Tower requires 41% less surface area than the Ultra Tower which gives it a small advantage on placement in tight spaces.
