Frequency Response
Viva Utopia Colour Evo has a frequency range of 39-40k Hz whereas Stella Utopia EM Evo has a frequency range of 22-40k Hz. With a minimum frequency of 22Hz, the Stella Utopia EM Evo can go significantly deeper on the low side and provide stronger bass compared to the Viva Utopia Colour Evo's min frequency of 39Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Center Channel class in our database.
Low Frequency
Center Channel 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
Viva Utopia Colour Evo and Stella Utopia EM Evo have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Viva Utopia Colour Evo sensitivity is rated at 92 dB and the Stella Utopia EM Evo's is at 94 dB. This 2 dB difference makes the Focal Stella Utopia EM Evo a more sensitive speaker compared to Focal Viva Utopia Colour Evo, hence will play louder with the same amount of watts.
Sensitivity
Center Channel 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.
Stella Utopia EM Evo can handle a max power of 1000 watts RMS, whereas Viva Utopia Colour Evo has a max power handling value of 600 watts RMS, 400 watts less than the Stella Utopia EM Evo.
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.

In this section, we are going to compare Focal Viva Utopia Colour Evo's and Focal Stella Utopia EM Evo's external dimensions. Focal Viva Utopia Colour Evo has external dimensions of 394.0 x 1345.0 x 670.0mm (15-1/2 x 52-15/16 x 26-3/8inch) whereas Focal Stella Utopia EM Evo has external dimensions of 1558.0 x 553.0 x 830.0mm (61-5/16 x 21-3/4 x 32-11/16inch).
Focal Viva Utopia Colour Evo is 1164mm shorter and 160mm less deeper than Focal Stella Utopia EM Evo but it is also 792mm wider.
Size, drawn to scale
Both speakers and both views share one scale, so everything here is directly comparable. Hover a box for its dimensions.
One scale for both, standing on the same surface and pushed back to the same wall, so the deeper one visibly sticks out further.
Focal Viva Utopia Colour Evo needs about 96% more floor or shelf area. Focal Stella Utopia EM Evo is 160mm deeper, so it stands that much further out from the wall. Focal Stella Utopia EM Evo is 1164mm taller.
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 Viva Utopia Colour Evo is approximately 9011.5cm2 / 1,396.8inch2 and base area of the Focal Stella Utopia EM Evo is approximately 4589.9cm2 / 711.4inch2. The Viva Utopia Colour Evo requires 96% more surface area than the Stella Utopia EM Evo which gives it a small disadvantage on placement in tight spaces.
