Theva No3 features a 1" TNF Al/Mg inverted dome Tweeter , a 6.5" Midrange and 2 x 6.5" Slatefiber Woofer with a Crossover frequency at 270 Hz - 2700 Hz. 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
Theva No3 has a frequency range of 48-28kHz 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 Theva No3's min frequency of 48Hz.
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 Floor-standing class in our database.

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
Theva No3 and Ultra Tower have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Theva No3 sensitivity is rated at 91 dB and the Ultra Tower's is at 88 dB. This 3 dB difference makes the Focal Theva No3 a more sensitive speaker compared to SVS Ultra Tower, 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.
Theva No3 can handle a max power of 300 watts RMS from the amp the whereas Theva No3 has a max power handling value of 250 watts RMS , 50 watts less than the Ultra 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
Ultra Tower features Binding post posts which make bi-amping or bi-wiring possible. Theva No3 has a Binding post which doesn't feature bi-amping/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 Focal Theva No3's and SVS Ultra Tower's external dimensions. Focal Theva No3 has external dimensions of 991.0 x 213.0 x 388.0mm ( 39 x 83/8 x 151/4) 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 142mm wider, 168mm taller and 57mm deeper than Focal Theva No3.
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 Focal Theva No3 is approximately 826.4cm2 / 128.1inch2 and base area of the SVS Ultra Tower is approximately 1579.8cm2 / 244.9inch2. The Theva No3 requires 48% less surface area than the Ultra Tower which gives it a small advantage on placement in tight spaces.
