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.)
In the following sections, we will get into more detail in order to better understand how the Focal Theva No3 and Focal Theva Center compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Drivers
One of the fundamental differences between these two speakers is that Theva No3 is a 3-way design whereas the Theva Center is a 2-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.

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 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 No3 has a frequency range of 48-28kHz whereas Theva Center has a frequency range of 59-28kHz. With a minimum frequency of 48Hz, the Theva No3 can go significantly deeper on the low side and provide stronger bass compared to the Theva Center's min frequency of 59Hz.
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 Theva Center have the same Impedance of 8 ohms and their sensitivity is also same at 91 dB.

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 250 watts RMS from the amp the whereas Theva Center has a max power handling value of 200 watts RMS, 50 watts less than the Theva No3.
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
Theva Center 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.
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 Focal Theva Center'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 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 781mm shorter and 134mm less deeper than Focal Theva No3 but it is also 318mm 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 No3 is approximately 826.4cm2 / 128.1inch2 and base area of the Focal Theva Center is approximately 1348.7cm2 / 209.0inch2. The Theva No3 requires 39% less surface area than the Theva Center which gives it a small advantage on placement in tight spaces.
