History
What size room are the Focal Diablo Utopia Colour Evo and Focal Viva Utopia Colour Evo speakers good for?
The size of the room in which you are planning to use these loudspeakers is an important decision
factor. Here we have compared their suitability to various sizes of environments considering their size
and max power parameters:

400 sq. ft / 36 m2.
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.)
The sections below take each area in turn: drivers, frequency response, physical size and what you get in the box.
Drivers
One of the fundamental differences between these two speakers is that Diablo Utopia Colour Evo is a 2-way design whereas the Viva Utopia Colour Evo is a 3-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.

Frequency Response
Diablo Utopia Colour Evo has a frequency range of 44-40k Hz whereas Viva Utopia Colour Evo has a frequency range of 39-40k Hz. With a minimum frequency of 39Hz, the Viva Utopia Colour Evo can go significantly deeper on the low side and provide stronger bass compared to the Diablo Utopia Colour Evo's min frequency of 44Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Bookshelf class in our database.
Low Frequency
Bookshelf 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
Diablo Utopia Colour Evo and Viva Utopia Colour Evo have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Diablo Utopia Colour Evo sensitivity is rated at 89 dB and the Viva Utopia Colour Evo's is at 92 dB. This 3 dB difference makes the Focal Viva Utopia Colour Evo a more sensitive speaker compared to Focal Diablo Utopia Colour Evo, hence will play louder with the same amount of watts.
Sensitivity
Bookshelf 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.
Viva Utopia Colour Evo can handle a max power of 600 watts RMS, whereas Diablo Utopia Colour Evo has a max power handling value of 200 watts RMS, 400 watts less than the Viva Utopia Colour 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.

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 718% more floor or shelf area. Focal Viva Utopia Colour Evo is 243mm deeper, so it stands that much further out from the wall. Focal Diablo Utopia Colour Evo is 37mm 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 Diablo Utopia Colour Evo is approximately 1101.7cm2 / 170.8inch2 and base area of the Focal Viva Utopia Colour Evo is approximately 9011.5cm2 / 1,396.8inch2.
