Drivers
One of the fundamental differences between these two speakers is that Ultra Evolution Bookshelf is a 2-way design whereas the Ultra Evolution Tower 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.

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 Bookshelf can handle a max power of 300 watts RMS from the amp the whereas Ultra Evolution Bookshelf 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
Both Ultra Evolution Bookshelf and Ultra Evolution Tower features dual binding post speaker terminals for bi-amping or bi-wiring.
SVS Ultra Evolution Bookshelf's Gold-plated 5-way terminals allows Bi-amping or 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 Bookshelf and Ultra Evolution Tower 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 Bookshelf's and SVS Ultra Evolution Tower's external dimensions. SVS Ultra Evolution Bookshelf has external dimensions of 382 x 220 x 295.6mm ( 11.14 x 8.66 x 11.64”) whereas SVS Ultra Evolution Tower has external dimensions of 1130 x 218 x 424mm ( 44.49 x 8.58 x 16.69”) .
SVS Ultra Evolution Bookshelf is 748mm shorter and 128mm less deeper than SVS Ultra Evolution Tower but it is also 2mm wider.
Base Surface Area Comparison
