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 No1 and Theva Center have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Theva No1 sensitivity is rated at 89 dB and the Theva Center's is at 91 dB. This 2 dB difference makes the Focal Theva Center a more sensitive speaker compared to Focal Theva No1, 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 No1 can handle a max power of 200 watts RMS from the amp the whereas Theva No1 has a max power handling value of 120 watts RMS , 80 watts less than the Theva Center.
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 Theva No1 and Theva Center features dual binding post speaker terminals for 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 No1's and Focal Theva Center's external dimensions. Focal Theva No1 has external dimensions of 391.0 x 213.0 x 261.0mm ( 153/8 x 83/8 x 101/4) 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 181mm shorter and 7mm less deeper than Focal Theva No1 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 No1 is approximately 555.9cm2 / 86.2inch2 and base area of the Focal Theva Center is approximately 1348.7cm2 / 209.0inch2. The Theva No1 requires 59% less surface area than the Theva Center which gives it a small advantage on placement in tight spaces.
