Theva No2 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 280 Hz - 2900 Hz. On the other hand, the Theva Center features a 1" TNF Al/Mg inverted dome Tweeter and 2 x 6.5" Slatefiber Woofer with a Crossover frequency at 2100 Hz.
Frequency Response
Theva No2 has a frequency range of 53-28kHz whereas Theva Center has a frequency range of 59-28kHz. With a minimum frequency of 53Hz, the Theva No2 can go significantly deeper on the low side and provide stronger bass compared to the Theva Center's min frequency of 59Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Floor-standing class in our database.
Low Frequency
Floor-standing 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
Theva No2 and Theva Center have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Theva No2 sensitivity is rated at 90 dB and the Theva Center's is at 91 dB. This 1 dB difference makes the Focal Theva Center a more sensitive speaker compared to Focal Theva No2, 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. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
Theva No2 and Theva Center have the same power range of 40-200 watts.
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.
Which plays louder on your 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
Theva Center features Binding post posts which make bi-amping or bi-wiring possible. Theva No2 has a Binding post which doesn't feature bi-amping/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 Focal Theva No2's and Focal Theva Center's external dimensions. Focal Theva No2 has external dimensions of 931.0 x 191.0 x 353.0mm (365/8 x 71/2 x 137/8) whereas Focal Theva Center has external dimensions of 210.0 x 531.0 x 254.0mm (81/4 x 207/8 x 10).
Focal Theva Center is 721mm shorter and 99mm less deeper than Focal Theva No2 but it is also 340mm wider.
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 No2 is approximately 674.2cm2 / 104.5inch2 and base area of the Focal Theva Center is approximately 1348.7cm2 / 209.0inch2. The Theva No2 requires 50% less surface area than the Theva Center which gives it a small advantage on placement in tight spaces.
