Stella Utopia EM Evo features a 1.1" Beryllium Inverted Dome Tweeter, a 6.5" Midrange and 1 x 13" W sandwich Woofer. On the other hand, the Maestro Utopia Evo features a 1.1" Beryllium Inverted Dome Tweeter, a 6.5" Midrange and 2 x 10.5" W sandwich Woofer.
Frequency Response
Stella Utopia EM Evo has a frequency range of 22-40k Hz whereas Maestro Utopia Evo has a frequency range of 25-40k Hz. With a minimum frequency of 22Hz, the Stella Utopia EM Evo can go slightly deeper then the Maestro Utopia Evo's min frequency of 25Hz.
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
Stella Utopia EM Evo and Maestro Utopia Evo have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Stella Utopia EM Evo sensitivity is rated at 94 dB and the Maestro Utopia Evo's is at 93 dB. This 1 dB difference makes the Focal Stella Utopia EM Evo a more sensitive speaker compared to Focal Maestro Utopia Evo, hence will play louder with the same amount of watts.
Sensitivity
Floor-standing 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 Maestro Utopia 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.

Input Type and Bi-Amping / Bi-Wiring
Both Stella Utopia EM Evo and Maestro Utopia Evo features dual binding post speaker terminals for bi-amping or 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 Stella Utopia EM Evo's and Focal Maestro Utopia Evo's external dimensions. 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) whereas Focal Maestro Utopia Evo has external dimensions of 1470.0 x 770.0 x 455.0mm (57-7/8 x 30-5/16 x 17-15/16inch).
Focal Maestro Utopia Evo is 88mm shorter and 375mm less deeper than Focal Stella Utopia EM Evo but it is also 217mm 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 Stella Utopia EM Evo needs about 31% more floor or shelf area. Focal Stella Utopia EM Evo is 375mm deeper, so it stands that much further out from the wall. Focal Stella Utopia EM Evo is 88mm 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 Stella Utopia EM Evo is approximately 4589.9cm2 / 711.4inch2 and base area of the Focal Maestro Utopia Evo is approximately 3503.5cm2 / 543.0inch2. The Stella Utopia EM Evo requires 31% more surface area than the Maestro Utopia Evo which gives it a small disadvantage on placement in tight spaces.
Weight Comparison The weight of a loudspeaker can become an important factor if you need to move and reposition the unit often. Weight of a speaker can also "sometimes" be an indicator of the rigidity of the enclosure and the quality of the internal components used. The Focal Stella Utopia EM Evo weighs 170.00kg / 374lbs and the Focal Maestro Utopia Evo weighs 116.00kg / 255.2lbs. This makes the Stella Utopia EM Evo 47% heavier than the Maestro Utopia Evo.
Here is a comparison of how Stella Utopia EM Evo and Maestro Utopia Evo's weights compare with the average, max and min weights in Passive Floor-standing class.

Siblings in Focal's Utopia III Evo series, so they share a family sound. It comes down to size, output and price.
| Area | Better | Why |
|---|
| Bass | A | Focal Stella Utopia EM Evo digs deeper - 22Hz against 25Hz. A subwoofer would even that out. |
| Amplifier needs | evenly matched | Similar sensitivity (94dB vs 93dB) - both want much the same power. |
| Headroom | A | Focal Stella Utopia EM Evo takes more power (1000W vs 600W) - more in hand in a big room. |
| Size | depends | Focal Maestro Utopia Evo is easier to place; Focal Stella Utopia EM Evo is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | depends | Focal Stella Utopia EM Evo: bi-amping; Focal Maestro Utopia Evo: bi-amping. |
| Price | B | Focal Maestro Utopia Evo is cheaper - $79,998 against $149,998, about 47% less; arguably a different class. |
A Focal Stella Utopia EM Evo B Focal Maestro Utopia Evo
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
The usual trade-off: Focal Stella Utopia EM Evo measures better, Focal Maestro Utopia Evo costs about about 88% more% less. Whether that gap is worth the money is the call only you can make - and in a normal room it is often smaller than the numbers suggest. Think about the whole system, not just the speakers: the roughly $70,000 saved by taking the cheaper pair would buy a subwoofer or a better amplifier, and either usually does more for the sound than the difference between these two.
And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
