Ultra Bookshelf and Ultra Tower are members of SVS's Ultra series of speakers. Below you can find the loudspeakers from this series.
What size room are the SVS Ultra Bookshelf and SVS Ultra Tower speakers good for?
The size of the room in which you are planning to use these loudspeakers is an important decision
factor. Here we have compared their suitability to various sizes of environments considering their size
and max power parameters:

Average Floor Height: 9" / 2.7m. Typical room sizes differ from country to country, and the actual
listening experience changes depending on floor height, room shape, surface materials, listening
position, speaker locations, etc.)
The sections below take each area in turn: drivers, frequency response, physical size and what you get in the box.
Drivers
One of the fundamental differences between these two speakers is that Ultra Bookshelf is a 2-way design whereas the Ultra 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.

Ultra Bookshelf features a 1" aluminum Hard-Dome Tweeter and 1 x 6.5" Composite glass-fiber Woofer with a Crossover frequency at 2000Hz. On the other hand, the Ultra Tower features a 1.0" aluminum Dome Tweeter, a 6.5" Midrange and 2 x 8.0" Polypropylene Woofer with a Crossover frequency at 160HZ and 2000Hz.
Frequency Response
Ultra Bookshelf has a frequency range of 45-32k Hz whereas Ultra Tower has a frequency range of 28-32k Hz. With a minimum frequency of 28Hz, the Ultra Tower can go significantly deeper on the low side and provide stronger bass compared to the Ultra Bookshelf's min frequency of 45Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Bookshelf class in our database.
Low Frequency
Bookshelf Speakers
Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
Ultra Bookshelf and Ultra Tower have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Ultra Bookshelf sensitivity is rated at 87 dB and the Ultra Tower's is at 88 dB. This 1 dB difference makes the SVS Ultra Tower a more sensitive speaker compared to SVS Ultra Bookshelf, hence will play louder with the same amount of watts.
Sensitivity
Bookshelf Speakers
Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
Ultra Tower can handle a max power of 300 watts RMS, whereas Ultra Bookshelf has a max power handling value of 150 watts RMS, 150 watts less than the Ultra Tower.
Note that higher power handling does not make a speaker louder: that depends mainly on
sensitivity and impedance. The calculator below shows how loud each of these actually plays
on a real amplifier.

Starting with a popular amplifier - change it to the one you own, or any you are
considering, and watch both numbers move.
Input Type and Bi-Amping / Bi-Wiring
Both Ultra Bookshelf and Ultra Tower features dual binding post speaker terminals for bi-amping or bi-wiring.

Physical Specs
The size of a speaker can sometimes be 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 Bookshelf's and SVS Ultra Tower's external dimensions. SVS Ultra Bookshelf has external dimensions of 380.0 x 218.0 x 281.0mm (14-15/16 x 8-9/16 x 11-1/16inch) 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, 779mm taller and 164mm deeper than SVS Ultra Bookshelf.
Below you can see the front view size comparison of SVS Ultra Bookshelf and SVS Ultra Tower in scale.

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 Bookshelf is approximately 612.6cm2 / 95.0inch2 and base area of the SVS Ultra Tower is approximately 1579.8cm2 / 244.9inch2. The Ultra Bookshelf requires 61% less surface area than the Ultra Tower which gives it a small advantage on placement in tight spaces.
